Comprehensive Anatomy Lab Notes (AP1/AP2)
Lab Overview and Course Structure
Lab schedule and goals from transcript:
Week 1: body organization, membranes, and terminology.
Week 2: chemistry, pH, and buffers; first formal lab report due.
Rubrics: extremely detailed; instructor provides a video on how to assemble graphs; emphasis on APA formatting, grammar, and computer-generated graphs.
Optional proofreading: students can submit lab reports to instructor for proofreading before final submission.
Week 3: using the microscope.
Week 4: second formal lab report.
Weeks 5–7: tissues; focus on epithelial, connective, muscle, and nervous tissue (one week per tissue type).
Midterm in lab: tissue identification (weeks 5–8 focus area).
Weeks 8–13: skull, bones study, then muscles; bones first, then muscles (this sequencing is chosen to help learning).
Weeks 13+ (toward finals): dissection of brain, eye, and ear; final lab exam during finals week.
Exam structure: two practical lab exams (bone/muscle and tissue-focused); final lab exam covers bones, muscles, brain, eye, and ear.
Lecture vs lab exams: separate final for lecture (not covered here in detail).
Overall workload: high; lab is described as tiring but rewarding with thorough rubrics and guidance.
Attendance and SI support:
Attendance tracked for both instructor and SI (Alicia) sessions.
SI sessions: about sessions; attendance incentive adds up to points to the final lab practical score if you attend all sessions, with proportional bonuses for fewer attendances.
Example: 12/14 sessions → + points; 10/14 → + points; etc.
Practical logistics:
Lab working day schedule: lab lecture 1:00–2:15 (approx.), lab starts at 2:30, ends around 4:20–4:30.
Tuesday/Thursday session structure with SI on Thursdays.
Bring the lab manual to every session; page references to course materials and lab book are used during instruction.
Quiz and preparation:
Quick quiz in lab next week to accompany the introductory material.
Lab materials reference: page 15 in the lab book; chapter 1 (pp. ~13–15) in the textbook; narrated PowerPoint is recommended for review.
Emphasis on learning a new “language” of anatomy terms; lab focuses on anatomy (structure) while lecture emphasizes physiology (function).
Anatomy vs Physiology; Anatomic Position and Orientation
Anatomy vs Physiology:
Anatomy = structure (names, parts, relationships).
Physiology = function (how parts work together).
Relationship: form fits function; structure informs function and vice versa.
Anatomic position:
Stand upright, feet flat, arms at sides, palms facing forward, eyes forward.
Used as a reference frame for all directional terms and body part orientation.
Practical example given: behind an object, your right/left align with the object's right/left; in front, they appear opposite.
Important for surgical planning and avoiding errors (e.g., wrong kidney removal).
Supine vs Prone:
Supine: facing upward (palm up).
Prone: facing downward (face down).
Planes and regional orientation (overview):
Planes define how we section the body for viewing structures.
Regional terms define locations on the body (major landmarks).
Directional Terms (with Definitions and Examples)
Anterior (ventral) vs Posterior (dorsal)
Anterior/ventral = toward the front; e.g., sternum is anterior to the spine; esophagus is posterior to the trachea.
Superior (cranial/cephalic) vs Inferior (caudal)
Superior = above; e.g., clavicle is superior to ribs; ribs are inferior to the clavicle.
Cranial/cephalic vs Caudal
Cranial/cephalic = toward the head; caudal = toward the tail (not common in human anatomy practice for most lab contexts).
Medial vs Lateral
Medial = toward the midline; lateral = away from the midline (e.g., fibula is lateral to tibia; heart is medial to lungs).
Proximal vs Distal
Proximal = closer to the point of attachment to the trunk; distal = farther from the attachment point (e.g., elbow proximal to wrist; wrist distal to elbow).
Deep vs Superficial
Deep = away from the surface; superficial = closer to the surface.
Practical application examples from the lecture:
Directional terms are used to describe locations on bones, organs, and tissues.
The instructor emphasizes familiarity with these terms due to their frequent appearance on quizzes and exams.
Planes of the Body (Sagittal, Transverse, Frontal/Coronal)
Sagittal plane:
Divides the body into right and left portions.
A midsagittal cut divides exactly into equal right and left halves; not always needed for quiz, but the term sagittal is essential.
Transverse (horizontal) plane:
Divides the body into superior (upper) and inferior (lower) parts; cuts across the body.
Example: brain slices in a transverse section.
Frontal (coronal) plane:
Divides into anterior (front) and posterior (back) portions; also called coronal.
Notable teaching points:
These planes help visualize structures in different orientations; test questions will involve identifying planes and cross-sections.
Regional Terms (Selected, Commonly Tested)
Head/neck and face regions:
Nasal (nose), Buccal (cheek), Mental (chin), Frontal (forehead), Orbital (eye region), Auricular/Otic (ear).
Neck and shoulder:
Cervical (neck region), Deltoid (shoulder muscle area), Axillary (armpit).
Arm and forelimb:
Brachial (arm), Antecubital (front of elbow), Antebrachial (forearm).
Thorax and abdomen:
Thoracic region terms like Pectoral, Mammary are mentioned but not all are tested; focus areas include pleural/pericardial regions (see cavities section).
Hip to thigh regions:
Coxal (hip), Femoral (thigh), Patellar (kneecap), Inguinal (groin).
Forearm and hand:
Carpal (wrist), Palmar (palm), Digital (fingers).
Leg and foot:
Femoral (thigh), Patellar (knee), Tarsal (ankle), Calcaneal (heel), Plantar (sole).
Abdominopelvic regions (nine regions; four quadrants):
Nine regions: Umbilical, Right Hypochondriac, Epigastric, Left Hypochondriac, Lumbar (Right/Left), Right Iliac, Hypogastric, Left Iliac.
Four quadrants for quick clinical localization: Right Upper, Left Upper, Right Lower, Left Lower.
Note: The instructor highlights that some terms are commonly tested (circled/starred in notes): Cervical (neck), Buccal (cheek), Mental (chin), Axillary (armpit), Brachial (arm), Coxal (hip), Carpal (wrist), Femoral (thigh), Patellar (kneecap), Inguinal (groin), Gluteal (buttock), Sural (calf), Calcaneal (heel), Plantar (sole), Auricular/Otic (ear), Occipital (back of the head), Deltoid (shoulder).
Abdominal Quadrants and Regions: Practical Relevance
Four quadrants (RUQ, LUQ, RLQ, LLQ) and nine regions provide a framework to localize abdominal pain and potential organ involvement.
Example clinical reasoning:
Right Lower Quadrant pain may indicate appendicitis (appendix location).
Right Upper Quadrant pain may indicate gallbladder or liver issues.
Large portions of small intestine span both left and right quadrants.
The lecturer emphasizes familiarity with these zones even if not all organs are memorized for the quiz.
Cavities, Membranes, and Serous Membranes
Cavities and major compartments:
Dorsal cavity (protects the nervous system): cranial cavity and vertebral canal.
Ventral cavity (protects many visceral organs): subdivided into thoracic cavity and abdominal–pelvic cavity; the diaphragm separates thoracic from abdominal–pelvic regions.
Thoracic cavity contains:
Pleural cavities (two: right and left) housing the lungs.
Pericardial cavity housing the heart.
Mediastinum: not a cavity but a central region containing blood vessels, lymph nodes, and other structures.
Abdominal cavity houses digestive organs; pelvic cavity houses reproductive and some urinary structures; together they’re referred to as the abdominal–pelvic cavity.
Diaphragm:
A major muscle that separates the thoracic and abdominal cavities.
Membranes and serous membranes:
Visceral membrane: covers an organ directly (e.g., visceral pericardium around the heart; visceral pleura around the lungs).
Parietal membrane: lines the cavity itself (e.g., parietal pericardium, parietal pleura).
Serous fluid: a lubricating fluid between visceral and parietal layers that reduces friction during organ movement.
Common serous membrane examples:
Pleura (around the lungs)
Pericardium (around the heart)
Peritoneum (around abdominal organs)
Clinical conditions related to serous membranes:
Pleurisy: inflammation of the pleura around the lungs, causing sharp pain with breathing.
Pericarditis: inflammation of the pericardium surrounding the heart, causing a rubbing sound when listening to the heart.
Peritonitis: inflammation of the peritoneum lining the abdominal cavity; can result from GI tract leakage or wounds and can be severe.
Function and protection rationale:
Cavities provide protection and room for organ growth during development.
The bony rib cage and sternum protect the heart and lungs; bone structure also aids in CPR by providing a rigid chest wall to compress.
Practical Visuals and Memory Aids
Fist-and-balloon analogy for serous membranes:
Fist represents an organ; visceral membrane covers the fist; parietal membrane lines the surrounding cavity; serous fluid sits between the two layers to reduce friction.
Quick orientation rules:
Pleural = lungs; Pericardial = heart; Peritoneal = abdomen.
The diaphragm is the separator between thoracic and abdominal cavities.
Exam and Quiz Preparation Tips
Expect questions on:
Anatomic position and its importance for orientation and surgical planning.
Directional terms and their relationships (anterior/posterior, superior/inferior, medial/lateral, proximal/distal, deep/superficial).
Planes of the body (sagittal, transverse, frontal/coronal).
Regional terms (especially the starred terms). Be able to name areas and provide simple examples.
Abdominal quadrants and nine regions; know how to identify RUQ, LUQ, RLQ, LLQ on a diagram and approximate organ locations.
Cavities, membranes, and serous membranes; identify visceral vs parietal layers and serous fluid; recognize pleurisy, pericarditis, and peritonitis.
Practice tasks mentioned:
Label a diagram with dorsal vs ventral, thoracic vs abdominal–pelvic regions, and the organs within each cavity.
Distinguish between visceral and parietal membranes on common organs.
Identify planes of section on example images and relate to anatomical orientation.
Quick Recap of Key Points (Concise List)
Anatomy vs physiology; anatomy focuses on structure, physiology on function; both are interdependent.
Anatomic position is the universal frame of reference; behind the object aligns right/left with the object’s right/left.
Supine vs prone; basic directional terms: anterior/ventral, posterior/dorsal, superior/cranial, inferior/caudal, medial, lateral, proximal, distal, deep, superficial.
Planes: sagittal (right/left), transverse (superior/inferior), frontal/coronal (anterior/posterior).
Regions and regional terms, with emphasis on commonly tested terms (cervical, buccal, mental, axillary, brachial, coxal, carpal, femoral, patellar, inguinal, occipital, auricular, deltoid, gluteal, sural, calcaneal, plantar, inguinal, etc.).
Abdomen: four quadrants and nine regions; practical clinical implications for pain localization.
Cavities and membranes: dorsal vs ventral; thoracic (pleural, pericardial, mediastinum), diaphragm, abdominal/pelvic; serous membranes (visceral vs parietal) and serous fluid.
Common disorders: pleurisy, pericarditis, peritonitis; friction and pain implications.
Lab workflow, safety, and assessment structure: two formal lab reports; APA formatting; 쓰 graphs; lab safety gear; goggles; no biohazard in AP1; SI attendance incentives; labs are challenging but structured for progressive learning.
