An antagonist muscle means that when one muscle is under tension, the other muscle relaxes. For the Levator Scapulae, the antagonist’s muscles are, Latissimus Dorsi. Pectoralis Major.

What is the action of supraspinatus?

As part of the Rotator Cuff, supraspinatus helps to resist the gravitational forces which act on the shoulder joint to pull from the weight of the upper limb downward. It also helps to stabilize the shoulder joint by keeping the head of the humerus firmly pressed medially against the glenoid fossa of the scapula.

What is the function of the teres major?
