Pectoralis minor syndrome beneath it

Question 15

Quadrangular space

Answer 15

Superior - teres minor
Inferior - teres major
Lateral - humerus
Medial - long head triceps

Axillary n. And posterior circumflex artery

Question 16

Triceps origin and insertion

Answer 16

Long head (o) infraglenoid tubercle
Medial head (o) - posterior surface of the humerus distal to the radial groove
Lateral head (0) - postero lateral surface of the humerus proximal to the radial groove
Insertion - olecranon process

Coracobrachialis - origin insertion and action

Answer 20

(O) coracoid process
(I) middle third of the medial side of humerus
Actions - flexión and addiction of the shoulder
