These articulations allow the shoulder girdle to provide a large range of motion for the hand to locate itself maximally in space.

These generally move together as a unit. The muscles of the shoulder girdle are serratus anterior, pectoralis minor, levator scapulae, rhomboids, and trapezius.
How many muscles make up the shoulder girdle?
The five muscles that comprise the function of the shoulder girdle are the trapezius muscle (upper, middle, and lower), levator scapulae muscle, rhomboid muscles (major and minor), serratus anterior muscle, and pectoralis minor muscle.
Which are the 4 main muscles affecting movement of the shoulder girdle?
The four rotator cuff muscles include the supraspinatus, infraspinatus, teres minor, and subscapularis. [2][1] Other muscles that form the shoulder girdle include the pectoralis major, pectoralis minor, the deltoids, trapezius, and the serratus anterior.
What is the total number of bones in the shoulder girdle?
