• What are the 5 characteristics of the glenohumeral joint in the shoulder joint?
  
  Include:

• What kind of joint it is

• How it moves

What are the three joints that make up the shoulder girdle? 

Sternoclavicular, Acromioclavicular, Scapulothoracic

Sternoclavicular, Acromioclavicular, Scapulothoracic are the three joints that make up what

shoulder girdle

What is the relationship between movements at the shoulder joint and the shoulder girdle?

The shoulder joint and shoulder girdle work together in carrying out upper-extremity activities.

Is the shoulder girdle dependent on the shoulder joint?

No, the shoulder girdle is not dependent solely on the shoulder joint.

Why are muscles of the shoulder girdle important?

Muscles of the shoulder girdle are essential in providing a scapula stabilizing effect. This stabilization ensures that the shoulder joint has a stable base to exert force for powerful movements.

What are the 5 major muscles of the shoulder girdle?

HINT: Mnemonic to help remember the 5 major muscles: The Strong Rhinoceros Prefers Lemons

Trapezius, serratus anterior, rhomboids, pectoralis minor, and levator scapulae
