# Glandular Tissue & Lymphatic System ## Chapter 7: Glandular Tissue ### Summary This chapter details the endocrine and exocrine glands of the head and neck, their locations, secretions, functions, innervations, lymphatic drainage, and blood supply. Understanding these glands is crucial for dental professionals to identify disease processes. ### Key Information #### Gland Types - **Exocrine Gland:** Has a duct to empty secretions directly to the site of use (e.g., salivary glands). - **Endocrine Gland:** Ductless, secretes directly into the vascular system (e.g., thyroid gland). - Motor nerves regulate secretion flow; sensory nerves are also present. #### Lacrimal Glands - **Type:** Paired almond-shaped exocrine glands. - **Secretions:** Lacrimal fluid (tears) for lubricating the conjunctiva and eyeball. - **Location:** Lacrimal fossa of the frontal bone, just inside the lateral part of the supraorbital rim. - **Ducts:** Lacrimal ducts collect tears, which then pass to the lacrimal punctum, lacrimal sac, nasolacrimal duct, and finally drain into the inferior nasal meatus. - **Innervation:** Parasympathetic fibers from the greater petrosal nerve (branch of facial nerve), synapsing at the pterygopalatine ganglion. Postganglionic fibers reach the gland via maxillary branches of the trigeminal nerve and lacrimal nerve. - **Lymphatic Drainage:** Superficial parotid lymph nodes. - **Blood Supply:** Lacrimal artery (branch of ophthalmic artery); venous return via superior ophthalmic vein. - **Pathology:** Dry eye syndrome (DES) or keratoconjunctivitis sicca (KCS) due to reduced lacrimal fluid production. #### Salivary Glands - **Function:** Produce saliva to lubricate and cleanse the oral cavity, aid digestion, and contribute to immune defense. - **Control:** Autonomic nervous system. - **Types:** Major (large, encapsulated, named ducts) and Minor (smaller, more numerous, unencapsulated, shorter unnamed ducts). Both are exocrine. ##### Major Salivary Glands 1. **Parotid Salivary Gland** - **Type:** Largest encapsulated major salivary gland. - **Secretions:** Serous type only (25% of total salivary volume). - **Location:** Parotid space, posterior to mandibular ramus, anterior and inferior to each ear, overlying the masseter muscle. - **Duct:** Parotid duct (Stensen duct) opens into the oral cavity opposite the maxillary second molar. - **Innervation:** Efferent (parasympathetic) fibers from the otic ganglion of the glossopharyngeal nerve (ninth cranial nerve) via the lesser petrosal nerve. Postganglionic fibers carried by the auriculotemporal nerve (mandibular division of trigeminal nerve). Facial nerve passes through but does not innervate. - **Lymphatic Drainage:** Deep parotid lymph nodes. - **Blood Supply:** Transverse facial artery (branch of external carotid artery); venous return via retromandibular vein. - **Pathology:** Enlargement and tenderness with mumps (parotitis), most salivary gland cancers involve the parotid. 2. **Submandibular Salivary Gland** - **Type:** Second largest encapsulated major salivary gland. - **Secretions:** Mixed serous and mucous (60-65% of total salivary volume). - **Location:** Submandibular fossa in the submandibular space, inferior and posterior to the body of the mandible. - **Duct:** Submandibular duct (Wharton duct) opens at the sublingual caruncle in the floor of the mouth. - **Innervation:** Efferent (parasympathetic) fibers of the chorda tympani nerve (facial nerve) synapsing in the submandibular ganglion. Postganglionic fibers delivered by the lingual nerve (mandibular division of trigeminal nerve). - **Lymphatic Drainage:** Submandibular lymph nodes. - **Blood Supply:** Glandular branches of the facial artery; venous return mainly by the facial vein. - **Pathology:** Most common site for salivary stones (sialoliths). 3. **Sublingual Salivary Gland** - **Type:** Smallest, most diffuse, and only unencapsulated major salivary gland. - **Secretions:** Mixed, predominately mucous (10% of total salivary volume). - **Location:** Sublingual fossa in the sublingual space at the floor of the mouth, deep to the sublingual fold, anterior to the submandibular gland. - **Ducts:** Ducts of Rivinus (8-20 small ducts) open along the sublingual fold; sometimes form a larger Bartholin duct opening at the sublingual caruncle. - **Innervation:** Same as submandibular gland: efferent (parasympathetic) fibers of the chorda tympani nerve (facial nerve) and submandibular ganglion. Postganglionic fibers delivered by the lingual nerve (mandibular division of trigeminal nerve). - **Lymphatic Drainage:** Submandibular lymph nodes. - **Blood Supply:** Sublingual artery (off lingual artery); parallel venous return. ##### Minor Salivary Glands - **Type:** More numerous than major glands, unencapsulated. - **Secretions:** Mainly mucous, except von Ebner glands (serous only). - **Location:** Scattered throughout oral mucosa (buccal, labial, lingual, soft palate, posterior hard palate, floor of mouth). Von Ebner glands associated with circumvallate lingual papillae. - **Ducts:** Single, short ducts directly into the oral cavity. - **Innervation:** Preganglionic from facial nerve, postganglionic from various branches of the trigeminal nerve. - **Lymphatic Drainage & Blood Supply:** Various nodes and arteries depending on location. - **Pathology:** Mucocele (blockage of duct from trauma). #### Thyroid Gland - **Type:** Largest endocrine gland (ductless). - **Secretions:** Thyroxine (hormone) directly into the vascular system to stimulate metabolic rate. - **Location:** Anterolateral regions of the neck, inferior to the thyroid cartilage, at the junction of the larynx and trachea. - **Innervation:** Sympathetic nerves through cervical ganglia (do not control secretion; pituitary gland regulates hormone release). - **Lymphatic Drainage:** Superior deep cervical lymph nodes. - **Blood Supply:** Superior and inferior thyroid arteries (possibly thyroid ima artery); venous return via superior, middle, and inferior thyroid veins. - **Pathology:** Goiter (enlarged thyroid gland), loss of mobility indicating neoplastic growth. #### Parathyroid Glands - **Type:** Usually four small endocrine glands (ductless). - **Secretions:** Parathyroid hormone directly into the vascular system to regulate calcium and phosphorus levels. - **Location:** Adjacent to or within the thyroid gland on its posterior surface (not visible or palpable). - **Innervation:** Same as thyroid gland: sympathetic nerves through cervical ganglia. - **Lymphatic Drainage:** Superior deep cervical lymph nodes. - **Blood Supply:** Primarily inferior thyroid arteries (possibly anastomotic branch between inferior and superior thyroid arteries); venous return via superior, middle, and inferior thyroid veins. #### Thymus Gland - **Type:** Endocrine gland (ductless) and part of the immune system. - **Function:** T-cell lymphocytes mature here. Grows until puberty, then shrinks (involution). - **Location:** Thorax and anterior region of the base of the neck, inferior to the thyroid gland, superficial and lateral to the trachea, deep to the sternum. - **Innervation:** Branches of the vagus nerve (tenth cranial nerve) and cervical spinal nerves. - **Lymphatic Drainage:** Lymphatic system begins within the gland and terminates in the internal jugular vein (no afferent vessels). - **Blood Supply:** Inferior thyroid and internal thoracic arteries; venous return via veins in the posterior surface directly into brachiocephalic veins. - **Pathology:** Thymic rests (ectopic accessory thymic tissue). ## Chapter 10: Lymphatic System ### Summary This chapter covers the lymphatic system, its components (vessels, nodes, ducts, tonsils), and its role in fighting disease. It details the location, drainage patterns, and clinical significance of lymph nodes and tonsils in the head and neck. ### Key Information #### Lymphatic System Overview - **Components:** Vessels, nodes, ducts, tonsils. - **Function:** Part of the immune system, fights infection and cancer, drains tissue fluid (lymph). - **Lymphatic Vessels:** Parallel venous blood vessels, have one-way valves, drain lymph. - **Lymph Nodes:** Bean-shaped bodies in clusters, filter toxic products from lymph, contain lymphocytes (white blood cells), involved in lymphocyte production. - **Afferent vessels:** Lymph flows into the node. - **Efferent vessel:** Lymph flows out of the node at the hilus. - **Primary node (regional/master node):** First node lymph drains into from a particular region. - **Secondary node (central node):** Node that primary nodes drain into. - **Lymphatic Ducts:** Larger vessels formed by converging lymphatic vessels. - **Right lymphatic duct:** Drains right side of head and neck, right arm, and thorax into the junction of the right subclavian and right internal jugular veins. - **Thoracic duct:** Drains left side of head and neck, left arm, thorax, and entire lower half of the body into the junction of the left subclavian and left internal jugular veins. - **Tonsils:** Masses of lymphoid tissue near airway and food passages, contain lymphocytes, drain into superior deep cervical lymph nodes. #### Lymph Nodes of the Head ##### Superficial Lymph Nodes of the Head - **Occipital Lymph Nodes:** - **Location:** Posterior base of the head (occipital region). - **Drainage:** Scalp in the occipital region. - **Empties into:** Deep cervical nodes. - **Posterior Auricular, Anterior Auricular, and Superficial Parotid Lymph Nodes:** - **Posterior Auricular:** Posterior to each auricle and external acoustic meatus. - **Anterior Auricular:** Immediately anterior to each tragus. - **Superficial Parotid:** Superficial to each parotid salivary gland. - **Drainage:** External ear, lacrimal gland, adjacent scalp and face. - **Empties into:** Deep cervical nodes. - **Facial Lymph Nodes:** - **Location:** Along the facial vein. - **Subgroups:** Malar (infraorbital), Nasolabial (along nasolabial sulcus), Buccal (around labial commissure), Mandibular (superior to mandible, anterior to masseter). - **Drainage:** Skin and mucous membranes where located, drain superior to inferior. - **Empties into:** Deep cervical nodes via submandibular nodes. ##### Deep Lymph Nodes of the Head - Cannot be palpated extraorally. - **Deep Parotid Lymph Nodes:** - **Location:** Deep within the parotid salivary gland. - **Drainage:** Middle ear, auditory tube, parotid salivary gland. - **Empties into:** Deep cervical nodes. - **Retropharyngeal Lymph Nodes:** - **Location:** Near deep parotid nodes, at the level of the atlas. - **Drainage:** Posterior palate, pharynx, paranasal sinuses, nasal cavity. - **Empties into:** Deep cervical nodes. #### Cervical Lymph Nodes - Paired, unilaterally drain tissues (except submental nodes, which drain bilaterally). - Categorized into superficial and deep. - Medical community uses a 7-level classification (Node Levels I-VII). ##### Superficial Cervical Lymph Nodes - **Submental Lymph Nodes (Node Level I, Sublevel a):** - **Location:** Inferior to the chin, within the submental fascial space and submental triangle. - **Drainage:** Lower lip, chin, floor of mouth, apex of tongue, mandibular incisors with periodontium and gingiva. - **Empties into:** Submandibular nodes or directly into deep cervical nodes. - **Clinical Significance:** Risk for spread of cancers from floor of mouth, apex of tongue, mandibular anterior alveolar process, lower lip. - **Submandibular Lymph Nodes (Node Level I, Sublevel b):** - **Location:** Inferior border of the mandibular ramus, superficial to the submandibular salivary gland. - **Drainage:** Cheeks, upper lip, body of tongue, anterior hard palate, most teeth (except mandibular incisors and maxillary third molars), sublingual and submandibular salivary glands.

Surgical Technology FA Davis Final Exam Study Guide Flashcards

Absolutely — this is your AP U.S. Government Unit 1 test review, covering Chapters 1–3. I can turn this into a study guide with simple definitions + what you actually need to know for the test. 🇺🇸 AP Government Unit 1 Test Review 1. Foundational Documents Declaration of Independence Main idea: Government exists to protect people’s natural rights, and people can change/remove a government that violates those rights. Know: * Natural rights: life, liberty, and the pursuit of happiness * Consent of the governed: government gets its power from the people * Social contract: people give government authority in exchange for protection of rights * Influenced by John Locke * Justified the colonies’ separation from Britain Test connection: Popular sovereignty + social contract + limited government. ⸻ Articles of Confederation The first U.S. governing document. Strength: States had significant power. Problems: * Weak national government * Congress couldn’t directly tax * No executive branch * No national court system * Difficult to pass laws * Difficult to amend * Weak ability to regulate interstate commerce Why it matters: Its weaknesses helped lead to the Constitutional Convention. ⸻ U.S. Constitution Created a stronger federal government while limiting its power. Know: * Separation of powers * Checks and balances * Federalism * Popular sovereignty * Republicanism * Limited government ⸻ Federalist No. 10 Written by James Madison. Main issue: factions. Madison argued that a large republic could help control the effects of factions because there would be many competing interests. Key idea: Pluralism/competing factions can prevent one group from completely dominating government. ⸻ Federalist No. 39 Written by James Madison. Main question: Is the Constitution republican and federal? * Republican: people elect representatives * Federal: power is divided between national and state governments Madison argued that the Constitution created a system combining national and federal characteristics. ⸻ Federalist No. 51 Written by James Madison. Main idea: Checks and balances and separation of powers prevent government from becoming too powerful. Famous concept: “Ambition must be made to counteract ambition.” In simple terms: Give each branch enough power to check the others. ⸻ Brutus No. 1 Written by an Anti-Federalist. Main concern: The proposed Constitution gave too much power to the national government. Brutus feared: * Federal government would become too powerful * States would lose power * Necessary and Proper Clause could expand federal authority * Large republic might not adequately represent citizens Federalist vs. Brutus: Federalist Brutus Stronger national government Stronger state governments Large republic can control factions Large republic may be difficult to represent Constitution protects liberty Constitution could threaten liberty ⸻ 2. Court Cases McCulloch v. Maryland (1819) Issue: Could Congress create a national bank, and could Maryland tax it? Decision: No, Maryland could not tax the national bank. Why? The Constitution’s Necessary and Proper Clause gives Congress implied powers. This case strengthened: * Federal power * Implied powers * Supremacy of federal law Remember: McCulloch = Federal government wins over state government. ⸻ United States v. Lopez (1995) Issue: Could Congress use the Commerce Clause to prohibit guns near schools? Decision: No. The Supreme Court ruled that Congress had gone beyond its Commerce Clause authority. Why it matters: It limited federal power under the Commerce Clause. Easy comparison: McCulloch → expands federal power Lopez → limits federal power ⸻ 3. Constitutional Clauses Necessary and Proper Clause Also called the Elastic Clause. Allows Congress to make laws necessary and proper for carrying out its constitutional powers. Connection: Implied powers. ⸻ Supremacy Clause Federal law is generally supreme over conflicting state law. Think: Federal law > conflicting state law This was important in McCulloch v. Maryland. ⸻ Commerce Clause Gives Congress power to regulate interstate commerce. “Interstate” = between states. It has historically been an important source of federal power. Connection: United States v. Lopez. ⸻ Full Faith and Credit Clause States generally must recognize the public acts, records, and judicial proceedings of other states. Example: A court judgment from one state may need to be recognized in another state. ⸻ 4. Amendment Process — Article V The Constitution has a deliberately difficult amendment process. Proposal An amendment can be proposed by: * 2/3 of both houses of Congress OR * A convention called by Congress after 2/3 of state legislatures request one. Ratification It must then be ratified by: * 3/4 of the states Memorize: 2/3 → propose 3/4 → ratify ⸻ 5. Amendments 10th Amendment Powers not given to the federal government by the Constitution, and not prohibited to the states, are generally reserved to the states or the people. Think: Reserved powers. ⸻ 14th Amendment Very important for federalism and civil rights. Know: * Citizenship * Due process * Equal protection Equal Protection Clause States cannot deny people equal protection of the laws. Due Process Clause States must follow fair legal procedures and respect protected rights. Big connection: The 14th Amendment has been used to apply many constitutional rights to the states. ⸻ 6. Democracy Vocabulary Limited Government Government’s power is restricted by laws and the Constitution. Think: Government officials aren’t above the law. ⸻ Popular Sovereignty The people are the ultimate source of governmental power. Easy: People → government. ⸻ Republicanism People govern indirectly through elected representatives. ⸻ Social Contract The idea that people agree to give government some authority in exchange for protection and order. ⸻ Participatory Democracy Citizens are actively involved in government. Examples: * Voting * Protesting * Contacting representatives * Political campaigns * Community activism ⸻ Elite Democracy A relatively small group of influential individuals makes major political decisions. Think: Political power concentrated among elites. ⸻ Pluralist Democracy Different interest groups compete to influence government. Think: Many groups → competing interests → government responds Federalist No. 10 connects strongly to this concept. ⸻ 7. Legislature Structures Bicameral A legislature with two chambers. U.S. Congress: * House of Representatives * Senate Unicameral A legislature with one chamber. Easy: Bi = 2 Uni = 1 ⸻ 8. Plans for the Constitution Virginia Plan Wanted: * Strong national government * Three branches * Bicameral legislature * Representation based on population Favored larger states. ⸻ New Jersey Plan Wanted: * Stronger national government * Unicameral legislature * Equal representation for states Favored smaller states. ⸻ Great Compromise Solved the disagreement between the Virginia and New Jersey Plans. Created a bicameral Congress: House Representation based on population. Senate Each state gets 2 senators. Easy: House = population Senate = equal states ⸻ 9. Electoral College The system used to formally elect the president. Each state gets electoral votes based on its: * House representatives * 2 senators Total = House members + 2 senators Most states use a winner-take-all system for allocating electoral votes. Important: The president is not directly elected through one nationwide popular vote. ⸻ 10. Three-Fifths Compromise An agreement during the Constitutional Convention concerning how enslaved people would be counted for representation and taxation. For those purposes, enslaved people were counted as three-fifths of a person. This compromise was part of the Constitution’s original structure and reflected the institution of slavery. ⸻ 11. Separation of Powers Power is divided among three branches. Branch Main Function Legislative Makes laws Executive Enforces laws Judicial Interprets laws Think: Divide power. ⸻ 12. Checks and Balances Each branch can limit the power of the other branches. Examples: President → vetoes legislation Congress → overrides veto Senate → confirms presidential appointments Courts → judicial review Congress → can impeach federal officials Difference: Separation of powers = divide government power Checks and balances = branches limit each other ⸻ 13. Federalism Power is divided between: National government ↔ State governments This is different from separation of powers. Separation of powers: Between branches Federalism: Between levels of government ⸻ 14. Types of Federalism Layer Cake Federalism Also called dual federalism. Federal and state governments have separate areas of responsibility. Think: 🟫 National 🟨 State Separate layers. ⸻ Marble Cake Federalism Also called cooperative federalism. Federal and state governments work together and share responsibilities. Think: Swirled together. ⸻ 15. Preemption When federal law takes priority over conflicting state law. Connected to the Supremacy Clause. Think: Federal law can “preempt” state law. ⸻ 16. Types of Powers Exclusive Powers Powers belonging only to one level of government. Example: * Coining money → federal government ⸻ Delegated Powers Powers given to the federal government by the Constitution. Also called enumerated powers when specifically listed. Examples: * Declare war * Coin money * Regulate interstate commerce ⸻ Reserved Powers Powers reserved for states. Connected to the 10th Amendment. Examples: * Education * Local governments * Many licensing rules ⸻ Concurrent Powers Powers shared by federal and state governments. Examples: * Taxation * Courts * Law enforcement Memorize: Delegated → Federal Reserved → States Concurrent → Both ⸻ Implied Powers Powers that aren’t specifically written but are reasonably connected to Congress’s enumerated powers. Source: Necessary and Proper Clause. McCulloch v. Maryland = huge connection. ⸻ Inherent Powers Powers the national government is understood to possess because it is a sovereign nation. Example: * Conducting foreign relations ⸻ 17. Fiscal Federalism The use of federal money to influence state and local governments. Basically: Federal government → money → states/local governments ⸻ 18. Revenue Sharing The federal government gives states/local governments money with few restrictions on how it can be spent. States have significant flexibility. ⸻ 19. Incentives The federal government encourages states to do something by offering benefits, usually money. Example: Federal government: “Do X, and we’ll give you funding.” ⸻ 20. Categorical Grants Federal money given to states/local governments for a specific purpose. Very specific. Example: Federal government provides money specifically for a school nutrition program. Think: Categorical = category ⸻ 21. Block Grants Federal money given to states for a broad purpose, giving states more flexibility. Example: Money for healthcare rather than one extremely specific program. Difference: Categorical = specific Block = broad/flexible ⸻ 22. Mandates Requirements imposed by the federal government on state/local governments. Think: Federal government → “You MUST do this.” Some mandates come with funding; others may be unfunded mandates, meaning governments must comply without receiving enough federal money to cover the costs. ⸻ 23. Devolution The process of transferring power/responsibility from the federal government → state governments. Think: Federal → States ⸻ ⭐ THE BIG CONNECTIONS TO MEMORIZE These are especially useful because AP Gov questions often make you connect concepts. McCulloch v. Maryland Necessary & Proper Clause → implied powers → stronger federal government → Supremacy Clause U.S. v. Lopez Commerce Clause → limits federal power Federalist 10 Factions → large republic → competing interests → pluralism Federalist 51 Separation of powers → checks and balances → prevent tyranny Brutus 1 Fear of powerful national government → concern about federalism and individual liberty 10th Amendment Reserved powers → states 14th Amendment Equal protection + due process → limits state governments Great Compromise Virginia Plan + New Jersey Plan → bicameral Congress Fiscal Federalism Federal money → states → grants/incentives/mandates ⸻ 🧠 15 Things I Would Memorize FIRST If you’re short on time, know these cold: 1. Popular sovereignty = people have power 2. Republicanism = elected representatives 3. Limited government = government power is restricted 4. Federalism = national + state power 5. Separation of powers = three branches 6. Checks and balances = branches check each other 7. 10th Amendment = reserved powers 8. Necessary & Proper = implied powers 9. Supremacy Clause = federal law takes priority over conflicting state law 10. Commerce Clause = Congress regulates interstate commerce 11. McCulloch = expands federal power 12. Lopez = limits federal Commerce Clause power 13. Great Compromise = House by population, Senate equal 14. Categorical grant = specific 15. Block grant = broad/flexible The fastest memory trick: Federalism = levels Separation = branches Checks = limits 10th = states Necessary & Proper = implied Supremacy = federal wins Commerce = interstate McCulloch = expand Lopez = limit Categorical = specific Block = broad
