|
Definition
|
|
Term
What is secreted by serous acinar cells |

water, inorganic salts, salivary amylase |
|
|
Term
What cell types secrete glycoprotein mucin? |
|
Definition
|
|
Term
The salivary gland is an exocrine gland |
|
Definition
|
|
Term
Function of saliva that is not lubrication or starch breakdown |
|
Definition
Immunglobulins for defence |
|
|
Term
The primary secretion is in the duct of the exocrine gland |
|
Definition
False. Acinar cells are in the bulb not in the duct. |
|
|
Term
|
Definition
Sodium, potassium, chloride and bicarbonate |
|
|
Term
The concentration of potassium and bicarbonate in saliva is the same as in plasma |
|
Definition
False. Higher concentrations of these ion in saliva. |
|
|
Term
Name the inorganic ions that are extracted in the duct cells |
|
Definition
|
|
Term
The primary secretion is isotonic |
|
Definition
|
|
Term
Name the division of the ANS that predominantly controls saliva secretion |
|
Definition
|
|
Term
Atropine increases saliva secretion. |
|
Definition
False. Atropine is a mAChr antagonist which will inhibit atropine secretion. |
|
|
Term
Name the main component of the aqueous part of pancreatic juice |
|
Definition
|
|
Term
Name the non-aqueous component of pancreatic juice and give its function |
|
Definition
Enzyme digestion of fats, carbs and proteins |
|
|
Term
Secretin stimulates release of pancreatic juice via second messenger |
|
Definition
|
|
Term
Chyme in the duodenum stimulates reflex secretion of pancreatic juice and bile |
|
Definition
|
|
Term
Name the transporter through which chloride diffuses into the duct gland of the pancreas |
|
Definition
cystic fibrosis transmembrane conductance regulator |
|
|
Term
How is bicarbonate produced in the duct cells of the exocrine pancreas? |
|
Definition
CO2 diffuses into the cell. Combines with water to produce carbonic acid. This then disociates into bicarbonate and a proton. |
|
|
Term
Name the ion that is counter-transported with bicarbonate in the duct of the exocrine pancreas |
|
Definition
|
|
Term
Enzymes are secreted in the inactive form from the pancreatic acinar cells |
|
Definition
|
|
Term
Name the enzyme that activates proteases in the duodenum |
|
Definition
|
|
Term
Carboxypeptidase, trypsin and chymotrypsin are secreted in pancreatic juice |
|
Definition
|
|
Term
Other that proteases name 2 enzymes secreted by the exocrine pancreas |
|
Definition
|
|
Term
Pancreatic trypsin inhibitor prevents small amounts of active trypsin in the pancreas from becoming active within the pancreas |
|
Definition
|
|
Term
Distension of the stomach stimulates reflex pancreatic secretion |
|
Definition
True. Gastropancreatic Reflex |
|
|
Term
Name 3 phases of pancreatic secretion |
|
Definition
Cephalic (25%) Gastric (10%) Intestinal (65%) |
