This muscle has its origin on the lateral surface of most of the length of the ulna, and the dorso-lateral surface of the radius, as well as the interosseous ligament. Superior ramus meets ilium at acetabulum, inferior ramus meets ischium via the ramus of the ischium. Clavicle (a.k.a., collarbone) S-shaped. At the wrist-joint it is placed in front of the radial artery, and some filaments, piercing the deep fascia, accompany that vessel to the dorsal surface of the carpus. It supplies the skin of the lower two-thirds of the dorso-lateral surface of the forearm, communicating with the superficial branch of the radial nerve and the dorsal antebrachial cutaneous branch of the radial nerve.

Ulna--medial; Radius--lateral. largest tarsal bone. Shallow ball-and-socket joint. Note: stress fractures of tibia can feel like a "shinsplint," but are distinctly different. Navicular, cuboid and 3 cuneiforms make up rest of tarsus. The dorsal branch (ramus dorsalis; posterior branch) descends, along the dorsal surface of the radial side of the forearm to the wrist. Left and right pubis are joined via symphysis pubis--a semi-moveable (amphiarthrosis) joint. Forms a margin for the tendons of two muscles to the thumb. The tendon runs obliquely medial across the carpus to insert on the first metacarpal bone [ 16 ]. The proximal end terminates in the olecranon process and bears the semilunar notch on its upper surface. The accessory carpal bone ( Os carpi accessorium ) is elongated, the most palmarly situated of all the carpal bones and articulates with the palmar surface of the ulnar carpal bone.
