MUSCLE: SUBSCAPULARIS
DESCRIPTION:
The subscapularis is named according to its position on the scapula. It runs in front of the scapula across the chest wall and attaches on the front of the humerus. Its tendon merges with the joint capsule of the shoulder joint and helps stabilize it.

DESCRIPTION:
The teres minor is strongly linked with the infraspinatus and is located on the posterior aspect of the scapula. Both these muscles work together to produce the same actions at the shoulder joint.
ORIGIN:
Infraspinous fossa and lateral border of the scapula.
INSERTION:
Lateral posterior surface of the greater tubercle and […]

MUSCLE: CORACOBRACHIALIS
DESCRIPTION:
The coracobrachialis is a small muscle located across the front of the shoulder and runs in a similar direction to the short head of the biceps. It is found between the anterior deltoid and pectoralis major.
ORIGIN:
Coracoid process
INSERTION:
Middle one third of the medial surface of the humerus.
MUSCLE GROUPS:
The […]
