34
pronator quadratus
pronates forearm
35
flexor retinaculum
thick band of fascia that keeps tendons pinned down as they travel through the wrist
36
median nerve
- in front of medial epicondyle. - under/through pronator teres - between flexor digitorum profundus and superficialis
37
pronator teres syndrome
entrapment or compression of the median nerve, weak wrist flexion, no IP (interphalangeal) flexion at thumb

44
where do all extensor muscles come off of
lateral epicondyle
45
where do all flexor muscles come off of
medial epicondyle
46
extensor retinaculum

47
epicondylitis
inflammation of the tissues surrounding the elbow at either the medial or lateral epicondyle
48
golfers elbow
inflammation of tendons at the medial epicondyle (medial epicondylitis)
49
tennis elbow

sensory-motor nerve that, with its branches, supplies the thumb side of the arm and back of the hand
56
is the radius thicker or thinner at the distal end than the ulna
thicker
57
what does the radius articulate with
wrist
