What anatomical movement is the shoulder?

Overview. The human shoulder is the most mobile joint in the body. This mobility provides the upper extremity with tremendous range of motion such as adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction in the sagittal plane.

What is the anatomical name for the tip of the shoulder?

The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.

What are the three shoulder muscles called?

Shoulder muscles include the intrinsic muscles or scapulohumeral group, including the deltoid, teres major and four rotator cuff muscles. The extrinsic shoulder muscles are the trapezius, latissimus dorsi, levator scapula and rhomboids (rhomboid major and rhomboid minor).

What muscles are used in shoulder flexion?

The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during movement.

What is shoulder range of motion?

Abduction. Abduction is a term that refers to a body part moving out to the side,away from the midline of the body.

What is the movement of the shoulder?

The shoulder girdle has the following normal ranges of movement: Elevation, Depression, Adduction and Abduction. The shoulder joint has the following normal ranges of movement: Flexion, Extension, Adduction, Abduction and Medial Rotation. The elbow joint has the following normal ranges of movement: Flexion, Extension, Pronation and Supination.

What is normal shoulder abduction?

Shoulder abduction. Abduction occurs when you have arm movement away from the middle of your body. When you raise your arm out from the sides of your body, it’s an abduction of your shoulder.
