Salivary Glands Flashcards
Where is the parotid gland
Parotid region Superiorly - zygomatic arch Inferiorly - info border mandible Posteriorly - external ear and scm Bilaterally
What is the rough structure of the parotid gland
Lobular
Irregular
Superficial and deep
What kind of saliva does the parotid gland produce
Serous saliva
How does the parotid gland secretion reach the mouth
Via parotid duct which enters the mouth at upper 2nd molar
What are the three anatomical relationships the parotid gland has
Facial nerve
Eca
Retromandibular nerve
What does the facial nerve do in the parotid gland
CN 7
Between the superficial and deep fascia in a lame where it divides to its 5 terminal branches
What a re the 5 terminal branches of the facial nerve
Zygomatic Temporal Buccal Mandibular Cervical
What makes up the retromandibular Vein
The superficial temporal vein and the the maxillary vein
What supplies the parotid gland arterial supply and drains it
Arterial supply - posterior auricular and superficial temporal arteries
Drained by retromandibular vein
What si the innervation of the parotid gland
Sensory - auriculotemporal nerve v3
Autonomic - Glossopharyngeal at otic ganglion (+) auriculotemporal
Symp - sup cervical ganglion
Where is the sublingual gland found
The floor of the mouth
Sublingual fossa
Where does the sublingual secretion drain from in the mouth
Sublingual papillae
What si the sublingual gland supplied by in terms of blood
Sublingual and submental arteries from Lingual and facial artery
Corresponding veins drain
What si the innervation of the sublingual gland
Similar to submandibular gland
What kind of secretion from the sublingual gland
Mucous
What kind of secretion form the submandibular gland
Mixed
Where is the submandibular gland found
In the submandibular triangle
Superiorly - inf body of mandible,
Anteriorly - abd
Posteriorly - PBD
Where does the submandibular secretion come from in the mouth
Form the submandibular duct which terminates I sublingual papilla
What is the arterial supply of the submandibular gland
Submental arteries and corresponding veins for draining
What si the innervation of the submandibular gland
Parasymp - sup salivary nucleus through chorda tympani and lingual which gives secretomotor
Symp - duo cervical ganglion
How does the saliva get modified by salivary ducts
Sodium and chloride taken out of secretion whilst pottasium is pumped in
What are some function of saliva
Protection of teeth Integrity of teeth Buffer Initial digestion carbs Lubrication Taste Antibacterial
What are some components of saliva
Organic and inorganic Mucins Hi statins IgA Amylase Bicrabondat Pottasium Calcium Phosphate
What are salivary glands made up of
Sec acini
