1

The hormone that is stimulated by protein and hypoglycemia. It also is a CCK antagonist at the GI, while at the same time stimulates CCK to induce satiety

Pancreatic polypeptide

2

You advise a patient with low milk supply to take reglan. This drug works very well to increase milk production, but the mother complains of intense gastric cramping and diarrhea. This drug is an antagonist to which neurohormone?

Dopamine

3

This hormone is stimulated by the enteric nervous system to increase contraction of ductal cells in the pancreas and gallbladder. When this hormone is deficient in brain, it increases risk for anxiety and schizophrenia.

CCK

4

Enterochromaffin cells make this neurohormone to stimulate peristalsis and secretion

serotonin

5

This neurohormone is a parasympathetic inhibitor of smooth muscle contraction that is directed toward sphincters. It will stimulate secretion of water into pancreatic and bile ducts, but inhibit gastric secretion.

VIP

6

This neurohormone is made by gastric mucosa and increases gastric secretion.
Fun Fact: This neurohormone was first purified from the fire-bellied toad and also found in the CNS to signal via GPCRs and activate a variety of neurons involved in learning and memory.

Bombesin

7

The hormone that increases insulin with increasing fat

glucagon like peptide (or GIP),

8

The hormone that increases water bicarb secretions from the pancreas and bile ducts. It also inhibits H+ secretion

secretin

9

The hormone that is stimulated by fat and glucose and decreases gastric motility and H+ secretion, while stimulating insulin

GIP

10

This neurohormone is secreted by enteric nervous system and relaxes smooth muscle while inhibiting intestinal secretion

Neuropeptide Y

11

The neurohormone that stimulates motility and salivary secretion. It is co-secreted with ACh

substance P

12

A patient presents with chronic urticaria. The patient is prescribed a drug that relieves the urticaria when taken routinely, but now presents with achlorhydria and dyspepsia. Upon biopsy, there is atrophy of the enterochromaffin like cells of the oxyntic gland. Which hormone does this drug neutralize?

histamine

13

A patient presents with gastritis and is prescribed atropine, a muscarinic receptor antagonist. However, there is no change gastrin production, nor HCl secretion. This patient would respond better to a drug that antagonizes…

Gastrin releasing peptide

14

An eight year old girl weighs 186 lbs. Her serum GnRH and LH levels are very high for her age, and she has experienced menarche. Which hormone is contributing to precocious puberty in this case?

leptin

15

This hormone inhibits gastrin, secretin, CCK, VIP, pepsinogen secretion, gastric emptying, motility, and blood flow

somatostatin

16

This hormone stimulates appetite and GH. It suppresses adipocyte fat use.

Ghrelin

17

I cells

CCK

18

This hormone is associated with hunger. It can also be stimulated with antibiotics.

motilin

19

This hormone is secreted upon distention of the GI. It stimulates gastric cell proliferation and antral contractions

Gastrin

20

The hormones that increase during fasting

Motilin, pancreatic polypetide, ghrelin

21

The neurohormone that increases salivary secretions and inhibits motility

Norepinephine

22

S cell

Secretin

23

The hormones that stimulate H+ secretion

Gastrin, pancreatic polypetide, histamine, bombesin, ACh, Gastrin releasing Peptide

24

The hormones that inhibit gastric emptying

Gastrin, CCK, secretin, GIP, enteroglucagon, somatostatin, dopamine, norepinephrine

25

The hormones that contract smooth muscle

Gastrin, CCK, motilin, serotonin, substance P, enkephalins, ACh
