STRUCTURES WITHIN PAROTID GLAND
facial nerve
retromandibular vein
external carotid ( superficial temporal, maxillary )
medial relations of submandibular gland superficial part
hyoglossus m. , mylohyoid m.
lingual, hypoglossal n.
inferolateral relations of submandibular gland superficial part
investing facia , platysma m. , skin
crossed by facial v. + cervical part facial n.
submandibular LN
deep part of submandibular relations medial + lateral+above + below
inferolateral -> mylohyoid
medial –> styloglossus . hyoglossus
above lingual n.
below hypoglossal n.
submandibular duct runs btw
genioglossus, sublingual gland
medial relations of sublingual gland
genioglossus m. , lingual n. , submandibular duct .
nerve supply of parotid gland
inferior salivary nucleus ( medulla oblongata)Glossopharyngeal tympanic tympanic cavity tympanic plexus lesser petrosalenter otic gangelion
Post ganglionic fibers join 2 aureculutemporal roots ganglionic branches parotid
nerve supply of submandibular + lingual
pons –> facial –> chorda tympani–>walks with lingual ->submandibular gangelion –> postgangelionic–> glands
the ducts are made of
cuboidal epithelial cells
intercalated ducts join to form
striated ducts
cells type
ducts - interlobular- more distally
cuboidal - stratified cuboidal - stratified columner + mucos secreting cells
mouth proper is made of which type of cells
stratefied squamous
keratinized dorsal surface of tongue 2/3 + hard palate
non keratenized the rest + opening of the gland ducts to the mouth
what type of glands is the parotid
branched acinar
what type of glands is submandibular + sublingual
branched tubuloacinar
what does the acinar part -tubular part secrete in submandibular gland
lysozyme
tubular mucin
what does the acinar and intercalated disc in submandibular secrete
lactoferrin
what does the acinar part secrete in sublingual
lysozyme
posterior relations of the submandibular gland superficial part
Posterior belly of digastric and stylohyoid muscles, and parotid gland
lateral relations of submandibular gland superficial part
It is in contact with the submandibular fossa on the medial aspect of the mandible.
