Palmaris longus. Flexes hand and wrinkles skin of palm. Median nerve. Anterior/flexor compartment.
Absent in 14% of people (he might have said 10% in class)
Name the muscle, action, innervation, and compartment.

Extensor digiti minimi. Superficial posterior/extensor compartment of the forearm. Action is to extend the little finger. Innervated by the posterior interosseous nerve (deep motor branch of the radial nerve).

Name the muscle, action, innervation, and compartment.

Flexor digitorum superficialis. Flexes phalanges, wrist, and forearm. Median nerve. Anterior/flexor compartment.
Name the muscle, action, innervation, and compartment.

Anconeus. Superficial posterior/extensor compartment of the forearm. Action is to extend the forearm (it crosses the elbow joint). Innervated by the radial nerve.
Name the muscle, action, innervation, and compartment.

Flexor carpi ulnaris. Flexes and adducts hand. Ulnar nerve. Anterior/flexor compartment.
Name the muscle, action, innervation, and compartment.

Abductor pollicis longus. Deep posterior/extensor compartment of the forearm. Action is to abduct the thumb. Innervated by the posterior interosseous nerve (deep motor branch of the radial nerve).
Name the muscle, action, innervation, and compartment.

Flexor pollicis longus. Flexes thumb (surprise!). Anterior interosseous nerve. Anterior/flexor compartment.
Name the muscle, action, innervation, and compartment.

Flexor digitorum profundus. Flexes phalanges.
Radial half: anterior interosseous nerve. Ulnar half: ulnar nerve.
Anterior/flexor compartment.
Name the muscle, action, innervation, and compartment.

Extensor pollicis brevis. Deep posterior/extensor compartment of the forearm. Action is to extend the thumb. Innervated by the posterior interosseous nerve (deep motor branch of the radial nerve).
Name the muscle, action, innervation, and compartment.

Pronator quadratus. Pronates the forearm. Anterior interosseous branch of the median nerve. Anterior/flexor compartment.
This muscle is special because it goes directly from the ulna to the radius.
Name the muscle, action, innervation, and compartment.

Extensor pollicis longus. Deep posterior/extensor compartment of the forearm. Action is to extend the thumb. Innervated by the posterior interosseous nerve (deep motor branch of the radial nerve).
