Rotator Cuff Mechanics Shoulderdoc By Prof Lennard Funk

The rotator cuff rc is a common name for the group of 4 distinct muscles and their tendons which provide strength and stability during motion to the shoulder complex.

Anatomy rotator cuff muscles. Ive just added in the muscles here and well just take a look at the muscles that make up the rotator cuff and a look at their function. Laterally rotates the arm. The teres minor muscle originates on the lateral scapula border and.

Of the seven scapulohumeral muscles four make up the rotator cuff. This is the smallest rotator cuff. The four rotator cuff muscles supraspinatus.

Three of the four rotator cuff muscles are deep to the deltoid and trapezius muscles and cannot be seen unless those muscles are first removed and one is on the anterior side of the scapula bone and cannot be seen from the surface. The rotator cuff muscles are connected individually to a group of flat tendons which fuse together and surround the front the back and the top of the shoulder joint like a cuff on a shirt.

Originates from the infraspinous fossa of the scapula attaches to the greater tubercle of the humerus.

Each one of these muscles is part of the rotator cuff and plays an important role.

This holds your humerus in place and keeps your upper arm stable. In anatomy the rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder and allow for its extensive range of motion. The tendons attach the muscles to the bone and allow movement in the shoulder as well as providing strength to hold the ball in its socket.

The four muscles are the supraspinatus muscle the infraspinatus muscle teres minor muscle and the subscapularis muscle.
