Document Summary
Anatomy 9501 lecture 9: anterior forearm: 8 carpals, 5 metacarpals, 14 phalages (each finger has 3 except the thumb) These are named based on the names that are articulating: wrist joint radiocarpal jt. Carpalmetacarpal (cmc) jt: metacarpal phalangeal (mcp) jt, distal, middle, and proximal interphalangeal (dip, ** note, at the thumb since there is only 1 interphalangeal joint it is just called the interphalangeal joint, not middle, distal, or proximal. These all have a common insertion at the med. epicondyle. Insertion: pisiform, hook of hamate, base of 5th metacarpal. Palmaris longus: median nerve runs right underneath these ant. forearm muscles, ulnar nerve hides deeper in the ant. arm and makes it way into the forearm behind medial epicondyle = funny bone. Only 1 muscle makes up this intermediate layer: Insertion: forks to either side of 2-5th middle phalanges. Movement: hand flexion, 2-5th joint digit @ proximal interphalangeal joint.
