*Attached along it's whole length to the dorsal abdominal wall by mesentry.
*Attached along it's whole length to the dorsal abdominal wall by mesentry.
*The mesentry is relatively long for its most part, giving the small intestine a great deal of mobility.
*The mesentry is relatively long for its most part, giving the small intestine a great deal of mobility.
*The basic structure of the intestinal wall is conserved throughout the whole length of the alimentary tract, but there is greatest diversity in the epithelial layer.
*Within the tunica muscularis are muscles present for peristalis and mixing of food.
**There are two muscle layers; an inner circular and outer longitudinal layer.
**Between the two muscle layers is the '''myenteric plexus'''.
**Between the inner circular layer of muscle in the tunica muscularis and the submucosa is the '''submucosal plexus'''. (see regulation and control).
