what limits flexion at the humeroulnar joint
coronoid process or soft tissue approximation
what limits extension at the humeroulnar joint
limited by the olecranon process
capitulum is M/F?
Male
Radial head is M/F?

O/I/ N of the brachialis
O - distal 1/2 of anterior shaft of humerus
I - ulnar tuberosity + corned process
N - musculocutaneous
Action of the brachialis
- flexion at the elbow (always active) (uninfluenced by position)
O/I/N of the brachioradialis
O- lateral supracondylar ridge
I - lateral aspect of radial styloid
N - Radial N
Action of the Brachioradialis
flexion of the elbow
- most effective in mid range or pron/sup
O/I of pronator Teres
O - medial epicondyle of humerus and medial coronoid process
I - middle 1/3 of lat radius
Nerve innervation of Pronator teres
N - median n
