Hormones Flashcards
1
Q
acetylcholine
produced, received, action
A
produced by vagus
received by various
increases GI activity
2
Q
gastrin
A
produced by G cells (pyloric antrum, duodenum, pancreas)
received by parietal cells, ECL cells
stimulates HCl, stimulates histamine
3
Q
GIP
Gastric inhibitory peptide
A
- Produced by K-cells
- duodenum, jejunum
- secretes GIP when it sees acid
- duodenum, jejunum
- received by parietal cells, beta cells, adipocytes
- decrease HCl, motility
- increase insulin, lipoprotein lipase
4
Q
Secretin
A
- produced by S-cells
- duodenum, jejunum
- received by G-cells (stomach), pancrease, liver
- decreases gastrin
- increases HCO3 and bile production
5
Q
CCK
cholecystokinin
A
- produced by I-cells
- duodenum, jejunum
- release stimulated by fatty meal
- received by gallbladder, pancrease
- bile release
- enzyme release
6
Q
Somatostatin
A
- produced by D-cells
- pyloric antrum, duodenum, pancrease
- received by G-cells, parietal cells
- decrease gastrin, HCl
7
Q
Histamine
A
- produced by ECL cells
- stomach
- received by parietal cells
- increase HCL
8
Q
GRP
Gastrin-Releasing Peptide
A
- released by vagus
- received by G-cells
- stomach
- increase gastrin
9
Q
prostaglandins
A
- produced by mucosa
- stomach
- received by ECL cells
- decrease histamine
10
Q
seratonin
A
- produced by Enterochromaffin (EC) cells
- received by various
- increase motility, including diarrhea and vomiting
11
Q
motilin
A
- produced by M-cells
- duodenum, jejunum
- received by various
- increase MMC (myocin myoelectric complex)
12
Q
leptin
A
- produced by adipocytes
- received by CNS
- decrease hunger
13
Q
Ghrelin
A
- produced by ghrelinergic cells of GI tract
- Received by CNS
- increases hunger
14
Q
peptide YY
A
- produced by L-cells
- ileum, colon
- received by various
- decrease hunger, GI motility, various secretions
