200
What projection separates the infraspinatus and supraspinatus
Spine of the scapula
200
The round part of the humerus directly articulates with the glenoid fossa
Head of the Humerus
200
This rotator cuff muscle is located on the anterior portion of the scapula
Subscapularis
200
Straightening a joint or increasing the angle of the joint is known as what?
Extension
300
What shoulder joint is not considered to be a true joint?
Scapulothoracic Joint
300
What is this projection?
Acromion Process
300
This projection is where the subscapularis inserts on the humerus
Lesser Tubercle
300
This rotator cuff muscle is located below the spine of the scapula
Infraspinatus
300
What is the main movement that the rotator cuff does?
internal rotation
400
This joint is stabilized by the rotator cuff muscles
Glenohumeral Joint
400
What is this projection?
Coracoid Process
400
This projection is where the majority of the rotator cuff attaches to
Greater Tubercle
400
This muscle has two tendons. One inserts on the glenoid and the other on the coracoid process. It aids in shoulder and elbow flexion

500
This joint is the only direct articulation of the extremity to the trunk?
Sternoclavicular Joint
500
A shallow, somewhat egg-shaped socket on the superior end, lateral side of scapula; articulates with the head of the humerus.
What is glenoid fossa
500
What is the name of the projection where the long head of the biceps lays?
Bicipital Groove or intertubercular groove
500
These hold the head of humerus against the glenoid fossa.
What are the rotator cuff muscles (supraspinatus, infraspinatus, teres minor, and subscapularis.)
500
What are the different scapulothoracic movements?
elevation, depression, upward rotation, downward rotation, protraction and retraction
