Rotator cuff muscles The four muscles of your rotator cuff keep the head of your upper arm bone, the humerus, from popping out of the socket of the shoulder blade. Supraspinatus is responsible for beginning the upward motion of your arm. After about 15 degrees, the deltoid and trapezius muscles do the work.

What muscles are involved in lifting?

Your LIFTING MUSCLES are your Quadriceps (thighs), Gluteal Muscles (Buttocks) and your Abdominal Muscles. Remember to use these muscles, NOT the small postural muscles attached to your spine!!! Following the above steps helps ensure you use your LIFTING MUSCLES and not your postural muscles.

What muscles are necessary to raise the arm above the shoulder?

The trapezius and serratus anterior muscles work in tandem to coordinate rotation and movement of the scapula to accommodate the full range of motion of the arm. Specifically, they facilitate abduction of the arm from 90 degrees and further upwards.

What are the two bones located at your lower arm?

Your arm is made up of three bones: the upper arm bone (humerus) and two forearm bones (the ulna and the radius).

What muscles raise arm overhead?

Your rotator cuff is made up of muscles and tendons that keep the ball (head) of your upper-arm bone (humerus) in your shoulder socket. It also helps you raise and rotate your arm….Each one of these muscles is part of the rotator cuff and plays an important role:

  • Supraspinatus.
  • Infraspinatus.
  • Teres Minor.
  • Subscapularis.
