If for some reason our goblet cells are non-functional, this will adversly affect [2010]

2. secretion of sebum from the sebaceous glands

3. maturation of sperms

4. smooth movement of food down the intestine

Which of the following is a sub-mucosal gland?

1. Oxyntic glands of stomach

2. Crypts of Lieberkuhn of small intestine

3. Brunner's glands of the duodenum

4. Goblet cells

A mass peristaltic movement is responsible for:-

1. Release of bile and pancreatic juice into the duodenum
2. Passage of chyme from stomach to duodenum
3. Vomiting
4. Defecation

The mucosal layer in the stomach form irregular folds known as:-
1. villi
2. lumen
3. rugae
4. crypts of Lieberkuhn

Which cells of ‘Crypts of Lieberkuhn' secrete antibacterial lysozyme?

(1) Argentaffin cells

(2) Paneth oaks

(3) Zymogen cells

(4) Kupffer cells

Which of the following statement is not correct ?

1. Brunner's glands are present in the submucosa of stomach and secret pepsinogen.

2. Goblet cells are present in the mucosa of intestine and secret mucus.

3. Oxyntic cells are present in the mucosa of stomach and secret HCl.

4. Acini are present in the pancreas and secrete carboxypeptidase

Which layer of the gut is responsible for peristalsis?

(1) Smooth muscles                             

(2) Mucosa

(3) Submucosa                                    

(4) Serosa

Waves of muscle contraction that move the intestinal content are:

1. Caused by-contraction of skeletal muscle

2. Regulated by liver secretions

3. Called peristalsis

4. Voluntary

Assertion      :       Hepatopancreas of prawn is equivalent to the liver and pancreas of higher animals.

Reason         :       Hepatopancreas stores the absorbed nutrients from stomach and midgut.
