The tendons can be subject to a considerable amount of wear and tear, or degeneration, especially during overhead activities which can lead to weakening of the rotator cuff tendons, through a condition know as impingement. The rotator cuff tendons are also subject to age related degeneration . An injury to these tendons can result in a weak painful, shoulder - due to tearing of the rotator cuff tendons. The tendons of four muscles form the rotator cuff. The muscles are called the supraspinatus, infraspinatus, teres minor, and subscapularis.
Tendons attach muscles to bones.
Muscles are able to move bones by pulling on these tendons. The part of the scapula that makes up the roof of the shoulder is called the acromion. Between the acromion and the rotator cuff tendons there is a bursa. The bursa is a lubricated sac of tissue that protects the muscles and tendons and allows the moving parts to slide against one another without too much friction. Lose one pound, Smoking costs.
