Strongest layer of the intestine

Q) Which is the strongest layer of the intestine?

a) Mucosa

b) Submucosa

c) Muscularis propria

d) Muscularis mucosa

Answer:

b) Submucosa is the strongest and most important layer for intestinal anastomosis. It has fibroblasts that will ultimately release collagen and hold the anastomosis together. This layer should be fully incorporated in the anastomosis.

Inverted Vs everted anastomosis of intestine debate has been log going on but now many prefer inverted because mucosa is exposed to mucosa and eventually degrades joining the two submuoca together to cause healing by primary intention.
