These are the 4 muscles of the rotator cuff and make up the acronym SITS


 Supraspinatus, Infraspinatus, Treres Minor and Subscapularis

100

Rotation of inferior angle of the scapula, laterally and superiorly, away from the vertebral column is known as

Scapular upward rotation

100

Girdle

100

The long thoracic nerve supplies this muscle

Serratus Anterior

100

Circumduction

200

Supraspinous fossa of the scapula is the ORIGIN of which muscle

200

I stop at the sternum and I curve to the acromion process

Clavicle

200

The bicipital grove is on this bone and is apart of?

humerous, joint

200

Deltoid Muscle

Axillary 

200

The four actions of the pectoralis minor muscle are

300

Shoulder lateral rotation, horizontal abduction, and stabilization are performed by 2 different muscles. What are they?

Infraspinatous and teres minor

300

Known as the "Protective arch" over the head of the humerous

400

Out of the 4 muscles, this one is inserted on the lesser tubercle

Subscapularis

400
After the initial abduction, every 2 degrees of shoulder abduction must be accompanied by 1 degree of scapular upward rotation. This 2:1 ratio is known as 

Scapulohumeral rotation

400

This muscles origin is on the coracoid process
