What are the two cells MAKING the salivia |
Serous cells and mucous |
|
|
Serous cells |
High in protein, low in carbohdyrate and has a clear cytoplasm |
|
|
Mucous cells |
High in carbs, low in protein, contains mucin |
|
|
Acinus (acini) |
TERMIAL portion of gland, smallest functional unit. Single layer of cuboidal epithelial cells serous or mucous surrounding a LUMEN which is just a space. This is where saliva is deposited by cells |
|
|
Serous Demilune |
A cap or bonnet of serous cells on TOP of a mucous acinus |
|
|
Myoepithelial cells |
On surface of acini, 4-8 cytoplasmic processes branching over acini Function - contract and squeeze acinus forcing saliva out into duct work (sits ontop of acinus like a octopus on a rock) |
|
|
Excretory Duct |
Saliva exits by the way of this duct into the oral cavity Structure - simple columnar epithelium to simple cuboidal and outer portion is STRATIFIED SQUAMOUS EPITHELIUM Function - exit for saliva |
|
|
Parotid |
LARGEST ENCAPSULATED gland provides 25% of salivary volume Type - mainly serous Location - anterior and inferior to ear Duct - parotid or stensons duct located oppsite of max 2nd molar at the parotid papilla |
|
|
Submandibular gland |
2nd largest encapsulated saliva gland, 60-65% Type - both serous and mucous Location - beneath mandible in submandibular fossa posterior to sublignual gland Duct - submandibular or whartons duct opening at caruncle. |
|
|
Sublingual salivary gland |
Smallest salivary gland (no capsule), provides 10% Type - both serous and mucous Location - Sublingual fossa Duct - sublingual or bartholins aka caruncle and along the folds |
|
|
Lobule |
Group of acini |
|
|
Lobe |
Group of lobules |
|
|
Septum |
Walls that seprate the lobes |
