histology of the oral cavity Flashcards
Vermillion border lacks salivary or sweat glands
causes dry lips
has a lot of blood supply so pinkish
Circumvallate has most of the taste buds
taste cell most important part of the taste buds
Flow of secretion = Acinar->Intercalated duct->
Serous acinar stain purple
Mucous are clear
to see striated duct surrounded by serous acinar
Striated or interv=calated duct are pale
The layers of the GI tract
Mucosa
Submucosa
Adevtitia
Serosa
What is the vestibule of the oral cavity?
The space between the lips, cheeks and teeth
The three types of oral mucosa
Lining mucosa
Masticatory mucosa
Specialized mucosa
Which papillae are rudimentary in humans?
Foliate papillae
What kind of salivary gland is associated with the circumvallate papillae?
von Ebner’s salivary glands
Which types of papillae have taste buds?
Foliate
Circumvallate
Fungiform
The types of cells in taste buds
Supporting cells
Basal cells
Neuroepithelial cells
Function of Ebner’s salivary glands
They empty into the deep, moatlike groove surrounding each vallate papilla. Continuous flow of fluid over the taste buds, wash away food particles so that the taste buds can receive and process new gustatory stimuli🥲
The structural unit of salivary glands
Salivon
The secretory unit of the salivary gland
Acinus
The intercalated ducts of intralobular ducts are lined by what epithelium?
Simple cuboidal cells
The strained ducts of intralobular ducts are lined by what epithelium?
Low columnar cells
Where is the parotid gland located?
Infratemporal region
The parotid duct opens into the mucosal surface, opposite which molar tooth
The second upper molar tooth
A viral infection of the parotid gland that can damage CNVll is
Mumps
Which is the smallest salivary gland
Sublingual gland
The neck of the tooth is also known as
The cervix
Teeth are anchored in an alveolar bone pocket by which ligament?
Periodontal ligament
