Document Summary
Anatomy 19: muscles of the forearm and hand. Superficial anterior muscles originate on the medial side of the arm (i. e. medial epicondyle of humerus) Anterior forearm muscles are considered the major flexors of the hand (wrist) and digits; innervated by median and/or ulnar nerve. Superficial group: five muscles; originate in the region of the medial epicondyle. Deep group: three muscles; originate on the anterior surfaces of the radius, ulna, and interosseous membrane. Distal quarter or anterior surface of ulna. Distal quarter of anterior surface of radius. Flexor carpi radials: flexes and and abducts hand; median nerve. Flexor carpi ulnaris: flexes hand and addicts hand; ulnar nerve. Flexor digitorum superficialis: flexes digits 2-5 and flexes hand; median nerve. Flexor digitorum profundus: flexes digits 2-5 and flexes hand; medial (ulnar) half by. Flexor pollicis longus: flexes digit 1 and flexes and; median nerve ulnar nerve, lateral (radial) half by median nerve.
