Caecum is small blind sac which hosts some symbiotic micro-organisms. From it a small finger like vestigial organ arises. This organ is called:

(1) Parotid gland

(2) Vermis

(3) Vermiform appendix

(4) Lacteals

Lacteals, lymph capillaries are found in:

(1) Spleen             

(2) Intestinal villi   

(3) Salivary gland  

(4) Mammary gland

Mucosa forms many small finger like villi in the:

(1) Stomach

(2) Colon

(3) Caecum

(4) Small intestine

Duodenal glands / Brunner's glands are present in:

(1) Submucosa

(2) Mucosa

(3) Muscularis

(4) Serosa

Mucosa forms irregular folds (rugae) in the:

(1) Ileum

(2) Stomach

(3) Jejunum

(4) Colon

The wall of alimentary canal from oesophagus to rectum posses four layers. The sequence of these layers is:

(1) Serosa → Mucosa → Submucosa → Muscularis

(2) Muscularis → Serosa → Mucosa → Submucosa

(3) Serosa → Muscularis → Mucosa → Submucosa

(4) Serosa → Muscularis → Submucosa → Mucosa

The opening of stomach into duodenum is guarded by:

(1) Cardiac sphincter

(2) Sphincter of Boyden

(3) Sphincter of Oddi

(4) Pyloric sphincter

Which layer of the gut is responsible for peristalsis?

(1) Smooth muscles                             

(2) Mucosa

(3) Submucosa                                    

(4) Serosa

Small intestine is distinguishable into 3 parts, a 'C' shaped ________ a long coiled middle portion _________ and a highly coiled:

(1) Ileum, jejunum, duodenum

(2) Duodenum, Jejunum, ilium

(3) Duodenum, jejunum, caecum

(4) Caecum, duodenum, ileum
