A muscular sphincter regulating opening of oesophagus into the stomach is called:
(1) Pyloric sphincter
(2) Cardiac Sphincter
(3) Sphincter of oddi
(4) Boyden sphincter
The narrow distal part of stomach leading to the intestine is called:
(1) Cardiac
(2) Pyloric
(3) Fundus
(4) None of these
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, ileum
(4) Caecum, duodenum, ileum
The opening of stomach into duodenum is guarded by:
(1) Cardiac sphincter
(2) Sphincter of Boyden
(3) Sphincter of Oddi
(4) Pyloric sphincter
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
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
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
Mucosa forms many small finger like villi in the:
(1) Stomach
(2) Colon
(3) Caecum
(4) Small intestine
Which layer of the gut is responsible for peristalsis?
(1) Smooth muscles
(2) Mucosa
(3) Submucosa
(4) Serosa
