The Subscapularis Muscle
>> YOUR LINK HERE: ___ http://youtube.com/watch?v=eE4hPaLvAmU
The group of muscles collectively known as the rotator cuff controls the motion of the head of humerus, the “ball” in the ball and socket joint of the shoulder (glenohumeral joint). • The “socket” part of the joint is the glenoid fossa of the scapula, so as the scapula moves so does the socket. • The rotator cuff muscles act to keep the ball of the shoulder joint secured in the right position in the socket. • The rotator cuff group comprises supraspinatus, infraspinatus, teres minor and subscapularis. Each of these muscles has a unique primary action, but they also act together as a stabilizing unit. • When used for primary action, subscapularis acts as an internal rotator, infraspinatus and teres minor as external rotators, and supraspinatus as an arm abductor. • For more information about NAT online courses, please visit https://nielasher.com/collections/nat...
