Definition of Supraspinatus muscle
Supraspinatus muscle: A muscle that is responsible for
elevating the arm and moving it away from the body.
The tendon of the supraspinatus muscle is one of four tendons that
stabilize the shoulder joint and constitute the rotator cuff.
Each of the four tendons of the rotator cuff hooks up to a muscle
that the shoulder in a specific direction. The four muscles whose
tendons form the rotator cuff are:
The supraspinatus muscle;
The subscapularis muscle, which moves the arm by turning it
inward (internal rotation);
The infraspinatus muscle, which assists the lifting of the arm
during turning the arm outward (external rotation);
The teres minor muscle, which also helps in the outward turning
(external rotation) of the arm.
Damage to the rotator cuff is one of the most common causes of
shoulder pain.
The term "supraspinatus" means "above the spine". The
supraspinatus muscle originates above the "spine" of the scapula (the
wingbone).
Common Misspellings: supraspinatus muscel
