1Clinical: Rotator cuff tear, painful arc syndromf
2Trapezius, Rhomboid major/minor, Levator scapularR. major: below spine, from t2-t5
R. Minor: at spine, C7-T1
Levator scap: above spine. C1-4
all innervated by dorsal scapular n.
dorsal scapular artery blood flow.
3Rotator cuff muscles: supraspinatus, infraspinatus, teres minor, teres majorsupraspinatus: suprascapular a and n
infra/ teres minor= curcumflex scap a.
teres minor= axillary n
infra= also suprascapular n
subscap= subscapular n and artery
4Non-rotator cuff: deltoid, teres majordeltoid: axillary n
all branches of axillary artery
teres major=
lower subscapular n

5Clinical: radial n. injury, triceps reflex testParalysis of the triceps (only partially) , brachioradialis, supinator, and extensor muscles of the wrist and fingers.
Loss of sensation
RESULT: Wrist-drop
inability to extend wrist and fingers at the metacarpophalangeal joints
triceps reflex
Tests the integrity of C7 nerve root and radial nerve
Tapping the distal end of the triceps where it inserts on olecranon elicits the reflex
6Triceps: Long head, lateral head and medial head of brachiiLong head RED
O: scapula
Lateral head YELLOW
O: posterior humerus, distal to the radial groove
Medial head (GREEN, under)
O: posterior humerus, proximal to the radial groove
All insert on the Olecranon
All innervated by Radial Nerve
Action:
Long head- extension and adduction shoulder
All extend the elbow.
7Anconeuslateral epicondyle of humerus
to olecranon
Innervation: Radial nerve
8deep a. of arm (profunda brachii)Triangular interval is formed by teres major (superior border), humerus (lateral border), and triceps long head (medial border).
Houses two structures:
Deep artery of the arm (Profunda Brachii) which is a branch from brachial artery
Radial nerve which extends from brachial plexus (C5-T1)
9Radial nerveProvides Cutaneous innervation to posterior arm
Radial nerve which extends from brachial plexus (C5-T1)
10Clinical: Suprascapular neuropathy, axillary nerve injuryaxillary Weakness and atrophy of the deltoid muscle and numbness on the side of the shoulder

13Upper subscapular nMotor : Superior portion of subscapularis m.
Origin: Posterior cord of the brachial plexus (C5, C6)
14Lower subscapular n.Motor : Inferior portion of subscapularis and teres major muscles
Origin: Posterior cord of the brachial plexus (C5, C6)
15Spinal accessory n.Motor: Sternocleidomastoid and trapezius muscles
Origin: C1-C5/C6 spinal nerve roots
16suprascapular nSensory : Glenohumeral and AC joints
Motor : Infraspinatus and Supraspinatus
Origin: Superior trunk (C5, C6)
