Salivary Glands Flashcards

Flashcards about salivary glands, created from lecture notes.

Where is the Parotid Gland located?

Below, in front, and behind the ear lobule, between the ramus of the mandible and mastoid process.

What covering surrounds the Parotid Gland?

Parotid sheath.

What separates the parotid gland from the submandibular gland?

Stylomandibular ligament.

What structures emerge at the Parotid Gland's apex?

Retromandibular vein and cervical branch of the facial nerve.

What structures emerge at the base (superior surface) of the Parotid Gland?

Superficial temporal vessels and auriculotemporal nerve.

What emerges from the anterior border of the parotid gland?

Temporal, zygomatic, buccal, and marginal mandibular branches of the facial nerve and parotid duct.

What is related to the superficial (lateral) surface of the parotid gland?

Parotid lymph node and great auricular nerve.

What is related to the anteromedial surface of the parotid gland?

Ramus of mandible and masseter muscle.

What is related to the posteromedial surface of the parotid gland?

Mastoid process with sternocleidomastoid muscle.

Name the intraglandular structures of the parotid gland

Facial nerve, Retromandibular vein, External Carotid Artery

Where does the facial nerve exit the skull?

Stylomastoid foramen.

During a parotidectomy, what must happen to the facial nerve?

Preserved.

What veins unite to form the retromandibular vein?

Superior temporal vein and maxillary vein.

What vein does the anterior division of the retromandibular vein join with?

Facial vein.

What vein does the posterior division of the retromandibular vein join with?

Posterior auricular vein.

What does the external carotid artery divide into at the level of the mandible neck?

Maxillary and superficial temporal arteries.

In the serous acini of the parotid gland, what form do the secretions take?

Zymogen granules.

What type of epithelium is found in the intralobular ducts of the parotid gland?

Simple cuboidal.

Where does the parotid duct open into?

Vestibule near the crown of the upper 2nd molar tooth.

Where do the parasympathetic secretomotor fibers come from for the parotid gland?

Otic ganglion via auriculotemporal nerve.

Where do the sympathetic fibers come from for the parotid gland?

Superior cervical ganglion.

What nerve provides sensory innervation to the parotid gland?

Auriculotemporal nerve.

What is the cause of Parotid mumps?

Viral infection of the gland.

What separates the submandibular gland from the parotid gland?

Stylomandibular ligament.

What is the Submandibular gland covered by?

Investing layer of deep cervical fascia.

What arteries supply the submandibular gland?

Facial and lingual arteries.

What is the lymphatic drainage of the submandibular gland?

Submandibular nodes

What nerve provides secretomotor fibers to the submandibular ganglion?

Chorda tympani nerve of facial nerve.

How does the submandibular ganglion connect with the lingual nerve?

Lingual nerve.

What nerve provides sensory innervation to the submandibular gland?

Lingual nerve.

What divides the submandibular gland into lobes?

Connective tissue septa.

What is a characteristic histological feature of the submandibular gland?

Mucous acini with serous demilunes.

Why is the submandibular duct more prone to stone formation than the parotid duct?

Secretion is more mucous.

Where is the incision given for excision of the submandibular gland?

1 inch below the angle of the mandible.

What type of gland is the sublingual gland mostly?

Mucous

Deep to what muscle does the sublingual gland lie?

Mylohyoid muscle.

Where do the ducts of the sublingual gland open into?

Sublingual fold in the floor of the mouth.

What innervates the Sublingual gland?

Submandibular ganglion via lingual nerve.

Which nerve is related to the base of the parotid gland?

Auriculotemporal nerve

Which nerve is the submandibular ganglion attached to?

Lingual nerve
