Document Summary

Muscular system upper limb. Anterior compartment: most originate from medial epicondyle of humerus via common flexor tendon. Innervation l a i c i f r e p u. Flexor carpi radialis (carpi = wrist) Pronator teres medial epicondyle. Base of 1st and 2nd metacarpals. Flexor digitorum e t a d i superficialis. Medial epicondyle, and some to ulna via 4 tendons, attach to base of middle phalanges (fingers 2- 5) Flexion of wrist and radial deviation (abduction) Prime mover of pronation of forearm. Flexion of digits (all but distal interphalangeal joint) and wrist. Base of distal phalanges (fingers 2- 5) via 4 tendons. Prime mover of flexion of wrist and fingers (all joints) Prime mover of flexion of thumb. Median (lateral ) and ulnar (medial ) Median nerve: palmaris longus tendon covers and protects median nerve; missing unilaterally in ~15% individuals. Posterior compartment: all muscles innervated by radial nerve. Function l a i c i f r e p u.
