5.3.3. Overview of the Stomach - Enterogastrones

Question 1

What are Enterogastrones?

Answer 1

Hormones released in response to a stimuli in the Duodenum

Question 2

What stimuli can cause the release of Enterogastrones?

Answer 2

1. Gastric Acid
2. Hypertonic Solutions
3. Fatty Acids
4. Monoglycerides

Question 3

What is the function of Enterogastrones?

Answer 3

Prevent further Acid Build up within the Duodenum

Question 4

By what mechanism can Enterogastrones prevent the further Acid build-up within the Duodenum?

Answer 4

1. By inhibiting Gastric Acid Secretion

2. By reducing Gastric Emptying

Question 5

What are the names of the Enterogastrones?

Answer 5

1. Secretin
2. Gastric Inhibitory Protein (GIP)
3. Cholecystokinin (CCK)

Question 6

By what mechanism does Secretin release inhibit Gastric Acid secretion?

Answer 6

1. The Presence of Acid in the Duodenum causes the release of Secretin
2. This acts on the G-Cells of the Stomach to decrease Gastrin Secretion
3. This causes a decrease in the Production of Gastric Acid

Question 7

By what mechanism does the Gastric Inhibitor Polypeptide (GIP) inhibit Gastric Acid secretion?

Answer 7

1. Fat in the Duodenum causes the release of GIP to be released
2. This acts on the G-Cells of the Stomach to decrease Gastrin Secretion
3. This causes a decrease in the Production of Gastric Acid
