Haustrae formed in between tenia coli

Taeniae coli are 3 thickened bands, formed by the longitudinal fibers in the muscular tunic of the large intestine, and extending from the root of the appendix to the rectum, where the fibers spread out and form a continuous layer encircling the tube; they include the :

taenia mesocolica: a thickened band of longitudinal muscle fibers of the large intestine along the site of attachment of the mesocolon(fascia connecting the colon to the retroperitoneum).

taenia omentalis: a band of longitudinal muscle fibers of the large intestine along the site of attachment of the greater omentum.

taenia libra: a the thickened band formed by anterior longitudinal muscle fibers of the large intestine

SMA

SMA extends down to terminate at the ileocecal junction. Along the way, the concave side (left) gives jejunal and ileal branches. Jejunal branches are more proximal and thicker while ileal branches are distal and thinner. The SB arteries branch and unite to form loops called arterial arcades. From these arcades, straight arteries may branch out (arteriae rectae). Colonic branches arise from the convex (right) side of the SMA.
