supraspinatus, infraspinatus, teres minor, subscapularis
This ligament usually requires Tommy John surgery following injury from repetitive valgus stress.
ulnar collateral ligament (UCL)
Performing a bench press on an incline may bias these fibers of the pectoralis major.
Clavicular
_____ muscles of the shoulder originate on the shoulder girdle and insert on the humerus.
Intrinsic
For everyone 2 degrees of overhead motion at the shoulder above 90, the scapula requires 1 deg of ______.
upward rotation
The cartilage ring around the glenoid fossa which helps to "deepen" the socket is known as the _____.
glenoid labrum
cubitus valgus
The concentric phase of a bent over row involves this movement of the shoulder against gravity
Shoulder extension
If I were to instruct you to flex your elbow to 90 deg, then flex your shoulder to 90 deg, then internally and externally rotate your shoulder, you would be moving in this plane of motion
The only connection of the UE to the axial skeleton is through the ____ joint, which is a ______ type joint.
SC; saddle

pivot; rotation
Push-up-plus or dolphin press are two exercises which strengthen this muscle into closed chain protraction.

Scapular retraction
External rotation
These two muscles are the only biarticular muscles of the arm, crossing both the shoulder and elbow joints (be specific).
Long head biceps, long head triceps
A chin-up performed with close grip and forearms supinated will likely bias this muscle.
Biceps brachii

Deltoid
