Anatomy Course One of the branches of the ulnar recurrent artery, which assists in the formation of an anastomotic network around the elbow joint. It arises below the elbow joint and rises between the brachialis and pronator teres muscles until it anastomoses with the ulnar collateral arteries. Supply Supplies brachialis and pronator teres muscles as
Anatomy Part of the distal tibiofibular joint. It attaches from the lateral surface of the anterior distal tibia, and travels obliquely downwards to attach to the lateral malleolus. Functions Holds the distal end of the tibiofibular joint together tightly. It is key for the skeletal framework and articulation of the foot at the ankle. Interested
Anatomy Course Follows its counterpart artery until it drains into the popliteal vein. Drain Drains the anterior compartment of the lower limb. Interested in taking our award-winning Pocket Anatomy app for a test drive?
Anatomy Course Branch of the common interosseous artery that originates from the ulnar artery. Rests upon the interosseous membrane of the forearm in the anterior compartment. Branches of the artery pierce the interosseous membrane where it then descends with the dorsal interosseous nerve to the wrist. Deep branches anastamose with the branches of the posterior
Anatomy Course Continuation of the popliteal artery when it passes through the interosseous membrane to cross into the anterior leg. It then descends on the anterior side of the interosseous membrane until it reaches the distal end of the tibia and ankle. It then continues into the foot as the dorsalis pedis artery.

Anatomy Origin: Tubercles of scaphoid and trapezium and adjacent flexor retinaculum. Insertion: Proximal phalanx and extensor apparatus of the thumb. Key Relations: Is one of the muscles of the thenar eminence of the hand. Functions -Abduction of the thumb at the carpopmetacarpol and metacarpophalangeal joints. -Also assists in thumb opposition and extension. Supply Nerve Supply:
Anatomy Origin: Medial process of the calcaneal tuberosity, flexor retinaculum and plantar aponeurosis. Insertion: Medial surface of the base of the proximal phalanx of the hallux (big toe). Key relations: Lies on the medial surface of the foot and contributes to a soft tissue bulge on the medial part of the sole of the foot.
Anatomy A strong fibrous band which encircles the head of the radius. It attaches to the anterior and posterior border of the radial notch of the ulna. The superior margin of this ligament blends with the fibrous membrane of the elbow joint capsule. The ligament also blends laterally with the radial collateral ligament. Functions The
Anatomy Origin: Pisiform and tendon of flexor carpi ulnaris. Insertion: Ulnar aspect of the base of the proximal phalanx of the little finger and ulnar border of the extensor apparatus of the little finger. Key Relations: Is one of the muscles of the hypothenar eminence of the hand. Functions Abduction of the little finger at
