Anatomy Course A branch of the anterior trunk of the internal iliac artery. It branches from the anterior trunk before the anterior trunk passes between the rami anterior rami of two of the sacral nerves. It courses medially along the posterior pelvic wall towards the rectum, where it joins with the superior and inferior rectal

Vignette Metatarsal – tarsal articulations; 1st – medial (1st) cuneiform, 2nd – all 3 cuneiforms, 3rd – lateral (3rd) cuneiform, 4th – lateral cuneiform and cuboid, 5th – cuboid. Interested in

Motion The metatarsophalangeal joints are ellipsoid type synovial joints formed between the sphere shaped heads of the metatarsal bones and the bases of the proximal phalanges of the toes.The joints allow flexion and extension with restricted abduction, adduction, rotation and circumduction. Stability The fibrous capsule surrounding the joint plays a role in its stability. Ligaments

Anatomy Course Branches from the deep brachial artery in the arm, about halfway down the humerus, before the deep brachial artery leaves the radial groove. It then descends to the elbow joint on the posterior aspect of the humerus until it reaches the elbow joint, where it anastomoses with the interosseous recurrent artery. Supply Contributes
