  1. Goblet cells

  2. Oxyntic cells

  3. Chief cells

  4. Enterochromaffic cells

Correct Option: A

Secretion of gastric juice is stopped by

zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

  1. Gastrin

  2. Secretin

  3. Enterogastrone

  4. Cholecystokinin

Show answer
Correct Option: C
Explanation:
A. Gastrin is secreted in stomach by the parietal cells and stimulates the secretion of gastric juices from the gastric glands.
B. Secretin is secreted in duodenum and stimulates the secretion of pancreatic juice but inhibits the secretion of gastric juices.
C. Enterogastrone is secreted from the duodenal mucosa and decreases the secretion of gastric juices.
D. Cholecystokinin is secreted from the duodenum and causes contraction of gall bladder and secretion of pancreatic juice into duodenum.
So, the correct answer is 'Enterogastrone'.

Which hormone stimulates the gastric glands to release the gastric secretion? 

zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

  1. Enterogastrone

  2. Gastrin

  3. Pancreozymin

  4. Cholecystokinin

Show answer
Correct Option: B
Explanation:
A. Enterogastrone is secreted from the duodenal mucosa and decreases the secretion of gastric juices.
B. Gastrin is secreted in stomach by the parietal cells and stimulates the secretion of gastric juices from the gastric glands.
C. Pancreozymin is the former name of cholecystokinin hormone that stimulates the contraction of gall bladder and release of pancreatic juices into duodenum.
D. Cholecystokinin is secreted from the duodenum and causes contraction of gall bladder and secretion of pancreatic juice into duodenum.
So, the correct answer is 'Gastrin'.

Hormone involved in discharge of pancreatic secretions is

zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

  1. Gastrin

  2. Cholecystokinin

  3. Secretin

  4. Both B and C

Show answer
Correct Option: D
Explanation:
A. Gastrin is secreted in stomach by the parietal cells and stimulates the secretion of gastric juices from the gastric glands.
B. Cholecystokinin is secreted from the duodenum and causes contraction of gall bladder and secretion of pancreatic juice into duodenum.
C. Secretin is secreted in duodenum and stimulates the secretion of pancreatic juice but inhibits the secretion of gastric juices.
Hence, both cholecystokinin and secretin are involved in discharge of pancreatic secretions. So both options B and C are correct. 
So, the correct answer is 'Both B and C'.

Enteroendocrine glands are present in 

zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

  1. Stomach

  2. Intestine

  3. Oesophagus

  4. Both A and B

Show answer
Correct Option: D
Explanation:
Enteroendocrine glands are the endocrine glands present in gastrointestinal tract. Endocrine glands secrete their products directly into the blood stream. For example, cholecystokinin is secreted from duodenum (part of small intestine) and stimulates the contraction of gall bladder to release bile juice and also stimulates secretion of pancreatic juice. An example of hormone secreted from enteroendocrine gland in stomach is gastrin which stimulates secretion of gastric juice.
Hence, both options A and B are correct.
So, the correct answer is 'Both A and B'.

Cholecystokinin and secretin are secreted by

zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

  1. Stomach

  2. Liver

  3. Duodenum

  4. Ileum

Show answer
Correct Option: C
Explanation:

  • Cholecystokinin is secreted from the duodenum and causes contraction of gall bladder and secretion of pancreatic juice into duodenum.
  • Secretin is secreted from duodenum and stimulates the secretion of pancreatic juice but inhibits the secretion of gastric juices.
So, the correct answer is 'Duodenum'.
