True
The medial border of the scapula above the scapular spine is the insertion point of the levator scapulae
True
The most palpable shoulder girdle muscle is the trapezius.
True
The origin of the subclavious is the superior aspect of the first rib at is junction with its costal cartilage.
True
The radial collateral ligament provides lateral stability to the elbow and is a rarely injured
True
The rotator cuff muscle group includes the subscapularis, supraspinatus, infraspinatus, and teres minor muscles
True
The serratus anterior performs abduction in the transverse plane.
True
The term "intrinsic" usually pertains to muscles within or belonging solely to the body part upon which they act.

False
Velocity is how fast an object is moving, or the distance an object travels I a specific amount of time.
False
