Salivary Gland Secretion Flashcards
How are salivary glands organized?
Like a tree
Serous demilunes
Serous cell
-Watery secretions
Mucous cell
-Mucin secretions
Intercalated duct
-Stem cells are around here
—Salivary gland regeneration
Striated ducts
-Modify the saliva
Basolateral vs apical?
Basolateral
-Outside the membrane
Apical
-Inside the membrane
Saliva produced where?
Acinar cells
Modified in the ductal cells
Parotid most produces which type of salivary secretion?
Serous
*Rich in amylase
Sublingual and minor salivary glands secrete mostly which type of salivary secretion?
Mucus
T.F - 0.5 liter of saliva every day.
True
Parasympathetic innveration to sublingual and submandibular from what?
Facial nerve via submandibular ganglion
Parasympathetic innvervation of parotid?
Glossopharyngeal via optic ganglion
Sympathetic post ganglion for all glands is from where?
Cervical gang of sympathetic chain
All receptors are located where?
Basolateral
AcH is associated with water or protein?
NE is associated with water or protein?
ACH - Water
NE - Protein
T/F - Initially, saliva is salty.
TRUE
As the saliva goes thru the striated duct what happens?
Na, Cl, and K are absorbed by the body
*So, saliva is not salty
Saliva is produced by what cells?
Acinar
What are the two stages of saliva production?
Fluid secretion
NaCl reabsroption and K secretion
-Cystic fibrosis pts don’t have stage 2, and they have salty secretions
