Salivary Glands Flashcards
The sympathetic part of the autonomic nervous system is responsible for what?
Fight or flight response
What is a periarterial plexus?
network of intertwining sympathetic nerves that are sitting on the surface of arteries
The sympathetic autonomic nervous system produces what kind of saliva?
Sticky
Sympathetic nerves are carried to the salivary gland via what?
Periarterial plexuses
The parasympathetic part of the autonomic nervous system is responsible for what?
Rest and digest
The parasympathetic nervous system produces what kind of saliva?
Runny
Parasympathetic nerves are delivered to the salivary glands via what?
Cranial nerves
What stimulates saliva production? 5
Smell
Taste
Nausea
Conditional reflexes
Pain (teething)
What inhibits saliva production? 5
Fatigue
Sleep
Fear
Dehydration
Exercise
Stimulatory and inhibitory factors for salivation act on which part of the brain
Medulla of brainstem
Stimulatory factors act on the medulla which then signals to the salivary gland using what?
Parasympathetic axons of cranial nerves
What are the two cranial nerves involved in production of saliva?
Facial nerve CN VII
Glossopharyngeal nerve CN IX
What r the 3 major salivary glands?
Parotid near ear
Submandibular gland under mandible
Sublingual under tongue
What are the minor salivary glands
1000s in oral mucosa for basal secretion
Where does the parotid gland drain?
Near 2nd maxillary molar via parotid papilla
Where does the submandibular gland drain?
Sublingual caruncle under the tongue
Where does the sublingual gland drain??
Superior into the mouth via sublingual fold
Which salivary gland is the largest?
Parotid gland
What kind of saliva does the parotid gland produce?
Serous (thin lubricating) saliva rich in amylase

The parotid gland is encapsulated by what?
Parotid fascia
Derived from investing layer of deep cervical fascia
