Q Which gastrointestinal motor activity is most affected by vagotomy?
A. Secondary esophageal peristalsis
B. Distension-induced intestinal segmentation
C. Oral stomach accommodation
D. Caudad stomach peristalsis

Explanation
Correct Answer:-
C. Oral stomach accomodation

Orad stomach accommodation depends
exclusively upon an intact vago-vagal
reflex. Distension-induced contraction of
gastrointestinal smooth muscle develops
as the result of long (vago-vagal) and
local (enteric nerves) reflexes. Secondary
esophageal peristalsis, intestinal segmentation, and migrating motor complexes are
unaffected by vagotomy, whereas caudad
stomach peristalsis is decreased but not
abolished by vagotomy.
