  • cephalic, gastric, intestinal

    The three phases of gastric secretion are called?

  • cephalic phase (reflex phase)

    -a relatively brief phase that takes place before food enters the stomach

    -smell, taste, sight, or thought of food triggers this phase

  • depression; loss of appetite

    ______ and _____ can suppress the cephalic reflex.

  • gastric phase

    - this phase is set in motion by local neural and hormonal mechanisms

    -triggered by entry of food into stomach

    -lasts 3-4 hours

  • stops HCL secretion; increases mucous secretions

    How does the stomach counteract high pH levels?

  • pancreas; gallbladder

    Cholecystokinin is secreted by the ______ and the _______.

  • pancreas; liver

    Secretin is secreted by the _______ and ______.

  • secretin

    –Stimulates secretion of bicarbonate-containing solution by the pancreas and liver

  • cholecystokinin

    -the major hormone responsible for gallbladder contraction and pancreatic enzyme secretion.

  • postprandially; small intestine

    Cholecystokinin is released ________ from the _______.

  • small intestine

    Secretin-producing cells are found along the

  • GI mucosal growth

    Secretin is involved in the regulation of _______.

  • GIP

    - released from K cells in the duodenum after food ingestion.

    -could allow for obesity resistance

  • central or peripheral administration

    _________ of GLP-1 strongly stimulates insulin release.

  • exendin-4

    •is useful in the regulation of glucose homeostasis in people with type 2 diabetes mellitus & reduces weight.

  • in the brain

    Where is GLP-2 found?

  • OXM

    -shares N-terminus of glucagon

    -is insulinotropic

    -blunts the rise in plasma glucose levels

  • myenteric plexus

    –increases the tone of the gut and the velocity and intensity of contractions.

  • submucosal plexus

    –controls local secretion, absorption, and muscle movements.
