Median nerve
32
Innervates posterior aspect of arm top to bottom. EXTENSOR
Radial nerve
33
What nerve damage results in no ability to extend arm?
Radial nerve damage
34
What never innervates upper arm, deltoid?
Axillary never
35
What nerve innervates all intrinsic muscles of hand BESIDES theynar muscle group
Ulnar nerve
36
The *axillary nerve* is underneadth & wraps around the surgical neck of the _____
Hummerus
37
Damage to the hummers can result in damage to what nerve?
The axillary nerve
38
Radial nerve runs through the midline o the ____
Midline of the hummerus
39
Fracture at the midline of the humerus can result in damage to what nerve?
Radial nerve
40
Ulnar nerve comes down the medial side of the medial _____ of the hummerus (funny bone in elbow)
Medial epicondyle of hummerus
41
Damage to the funny bone= damage to what nerve?
Damage to ulnar nerve
42
Shoulder muscle, attaches to clavicle & scapula, and hummerus.
Deltoid
43
What innervates the deltoid and what movement?
Innervation= axillary nerve Flexion= adduct shoulder
44
Muscle that attaches to humerus, clavicle head, and sternocostal head.
Pectoralis major
45
What movement of pectorals major?
Flexion, adduction & medial rotation of the humerus.
46
Muscles attaches to ribs 3,4,5 & corroniid process of scapula
Pectoralis minor
47
What movement of pectoralis minor?
Flex= depress coronoid process; ie bring scapula down.
48
Artery that comes out over rib 1 and turns into axillary artery
Subclavian artery

51
What artery does the axillary artery turn into after part 3
Brachial artery; down humerus.
52
What musculature makes up the brachium (upper arm) ?
Biceps, brachialis, triceps
53
Anterior muscle of upper arm, flex & supination of elbow.

63
Nerve under cubital fossa
Median nerve
64

Radial nerve
65
Nerve that innervates everything anterior in hand, goes into carpal tunnel and exits on the other side (palm)
Median nerve
66
