1
Which of the following statements about brachialis is correct? 1. innervated by radial nerve 2. arises from supraglenoid tuberosity of scapula 3. shoulder extensor 4. inserts into radius and ulna
4 only is correct
2
Name the lateral and medial support of the shoulder joint and their insertion?
Lateral = infraspinous and supraspinous muscle - greater tubercle of humerus Medial = subscapularis muscle - lesser tubercle of humerus
3
OIAN of brachiocephalicus?
O = cervico-thoracic fascia I = medial distal humerus A = protractor + shoulder extensor N = accessory nerve
4
OIAN of omotransversarius?
O = atlas I = acromion process of scapula A = protractor N = accessory nerve
5
OIA of serrated ventralis?
O = cervical vertebrae + first 8 ribs I = serrated face if scaoula A = protractor AND retractor
6
OIAN of trapezius?
O = cervico-thoracic fascia I = proximal spine of scapula A = abductor N = accessory nerve
7
OIAN of rhomboideus?
O = cervico-thoracic fascia I = dorsal border of scapula A = abductor
8
OIAN of pectorals?
O = sternum I = greater tubercle of humerus A = adductor
9
OIAN of lattisumus dorsi?
O = thoraco-lumbar fascia I = teres major tuberosity of humerus A = retractor + shoulder flexor
10
OIAN of biceps brachii?
O = supraglenoid tubercle of scapula I = ulnar and radial tuberosities A = shoulder extensor + elbow flexor N = musculocutaneous nerve
