Forearm - pronatory-flexor

Question 1

Pronator teres

Answer 1

origin - humeral head, medial epicondyle, ulna head, coronoid process
insertion - lateral surface of radius
action - forearm pronation + assist elbow flexion

Question 2

Flexor carpi radialis (FCR)

Answer 2

origin - medial epicondyle
insertion - base of 2nd + 3rd metacarpals
action - flexes and radial deviation

Question 3

Flexor carpi ulnaris (FCU)

Answer 3

origin - medial epicondyle + olecranon
insertion - pisifrom, hook of hamate, base of 5th metacarpal
action - flexes + ulnar deviation

Question 4

Flexor digitorum superficialis (FDS)

intermediate + deep

Answer 4

origin - medial epicondyle, coronoid process, anterior border of radius
insertion - middle phalanges of digits 2-5
action - flexes PIP joinys + assists in wrist/mcp flexion

Question 5
