How many degrees of freedom does the shoulder have?

Your shoulder has three degrees of freedom; pitch, yaw, and roll.

The bones of the shoulder?

are the humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collar bone). The roof of the shoulder is formed by a part of the scapula called the acromion.

How many movements does the shoulder have?

8= Flexion, Extension, Abduction, Adduction, Horizontal Flexion, Horizontal Extension, Internal Rotation, External Rotation.

Musculature involved in Shoulder Flexion?

Anterior Deltoid, Biceps Brachii (Short Head), Clavicular head pectoralis major, Coracoid Brachialis

Musculature involved in Horizontal Shoulder Flexion?

Anterior Deltoid, Biceps Brachii (Shorthead), Coracobrachialis, Pec Major.

Musculature involved in Shoulder Abduction?

Deltoids (Anterior, Medial (middle), Posterior), Biceps Brachii (Shorthead), Supraspinatus.

The Joints that make up the shoulder?

The main shoulder joint, called the glenohumeral joint, is formed where the ball of the humerus fits into a shallow socket on the scapula. This shallow socket is called the glenoid. The acromioclavicular (AC) joint is where the clavicle meets the acromion. The sternoclavicular (SC) joint supports the connection of the arms and shoulders to the main skeleton on the front of the chest.

The type of joint that is the shoulder?

The shoulder joint (glenohumeral) is a ball-and-socket joints.
