salivary glands anatomy Flashcards
what system supplies the salivary glands?
autonomic nervous system?
what is the response of the sympathetic supply to the salivary glands?
fight or flight
what kind of saliva does the sympathetic supply cause?
thick and sticky
what is the response of the parasympathetic supply to the salivary glands?
rest and digest
what kind of saliva is formed by the parasympathetic supply?
thin and running
how is the parasympathetic supply delivered?
facial nerve CNII
glossopharyngeal nerve CNIX
what gland is the largest?
the parotid
what is the pathway of the parotid gland?
PG-Parotid duct- parotid papillae
where is the parotid papillae located?
upper 2nd molars
what type of mucus does the parotid gland produce?
thin serous mucus
what is the parotid gland mucus rich in?
amylase
what encapsulates the parotid gland?
the investing layer of the deep cervical
as the parotid gland is encapsulated by the deep cervical fascia, what would swelling cause?
very painful
what arteries, veins and plexus is found within the parotid gland?
retromandibular vein
external carotid artery
facial nerve plexus
maxillary a/v and supra temporal a/v
name the structure posterior to the parotid gland
sternocleidomastoid muscle
name the structures medially to the parotid gland
styloid process and sylohyoid muscle and posterior digastric muscle
what is located anterior to the parotid gland?
massester
what is located laterly and medially to parotid gland?
mandibular ramus
what nerve innervates parotid gland?
glossopharangeal nerve CNIX
what is the pathway of the nerve to parotid gland?
CNIX to tympanic branch to tympanic plexus within petrous part of temporal bone to less petrosal to optic ganglion then post ganglionic auriculotemporal nerve to parotid gland
what gland sits below mylohyoid line and what gland sits above?
below submandibular
above-sub lingual
what does the deep and superficial SM gland wrap around?
mylohyoid muscle
what is the pathway for SM gland ?
sm gland to sm duct to sl caruncle
does that sm duct pass under or over the lingual nerve?
over
what kind of mucus is formed by sm gland?
serous and mucus
what is the pathway for sl gland to mouth?
sl gland to sl folds
what is the nerve pathway for the sublingual and submandibular gland ?
facial nerve within petrous part of temporal bone to chroda tympani to alongside lingual nerve to sM ganglion and postganglionic nerves to sm and sl gland
what type of mucous does sl glands produce?
thick mucous
