Anatomy 3 distinct, separated, equally spaced, longitudinal ribbons/straps of muscle (mesocolic, free, omental) along the length of ascending, transverse, descending and sigmoid colon, visible just below serosa, shorter than other corresponding colonic layers, thus puckering the colon between them (even more on contraction), and giving rise to haustra/sacculations; converge at either end – rectum, base

Anatomy Course A terminal branch of the ophthalmic artery (which is a branch of the internal carotid) – branches off where the ophthalmic artery travels posterior to the trochlea, exits the orbit medially, and ascends the forehead. Supply Along with the ophthalmic artery, it supplies the structures of the orbit of the eye, including the

Anatomy Course The sural communicating branch of the common peroneal nerve contributes to the sural nerve. It arises from the common peroneal nerve in the popliteal space and passes over the lateral head of the gastrocnemius muscle. About halfway down the leg, it joins with the medial sural nerve to form the sural nerve. Supply

Anatomy Course Originates from the tibial nerve just above the knee joint, between the heads of the gastrocnemius muscle. It descends superficially to the gastrocnemius muscle, and penetrates the deep fascia about halfway down the calf, to run subcutaneously. It continues down the leg, and passes around the lateral malleolus to continue to supply the

Anatomy Course Formed by the union of several veins in the abdomen that drain the region known as the embryonic midgut. It is formed in the mesentery, through which it ascends and then travels up behind the pancreas. Here it joins with the splenic vein to form the portal vein. Drain Drains the region of

Anatomy Course One of the terminal branches of the inferior mesenteric artery. It descends in the sigmoid mesocolon and crosses over the left internal iliac artery. It divides at the vertebral level of SIII, and continues to descend by the rectum where it anastomoses with the middle and inferior rectal arteries. Supply Supplies the rectum.
