What is shoulder protraction?

Scapular Abduction – Also called scapular flexion or protraction. A movement where the scapula moves laterally away from the spinal column. … It is a movement the opposite of abduction. Throwing the shoulder back and pinching the shoulder blades together illsutrates adduction of the shoulder girdles.

Which joint allows retraction and protraction?

sternoclavicular jointThe vertical axis through the sternoclavicular joint allows the scapula to be moved forward, an action termed protraction (as in “hunching the shoulders”). The action opposite to this would be one of retraction, or movement of the scapula backwards (as in “squaring the shoulders”).

What plane of motion is Circumduction?

Circumduction is the movement of a limb in a circular motion, as in swinging an arm around. Figure 38.3B. 1: Angular and rotational movements: Synovial joints give the body many ways in which to move. (a)–(b) Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion.

How do you do scapular retraction?

What muscles are weak in rounded shoulders?

What muscles do shoulder protraction?

Protraction is accomplished by the actions of the serratus anterior, pectoralis major, and pectoralis minor muscles. Retraction is accomplished by the actions of the trapezius, rhomboids, and latissimus dorsi muscles. The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles.

When the shoulder blades are retracted which muscle is the antagonist?

Retraction of the scapula is sometimes called adduction of the scapula. The scapula is moved posteriorly and medially along the chest wall. Muscles: rhomboideus major, minor, and trapezius are the prime movers. The muscles that protract and retract the scapula are antagonistic, that is, they have opposed actions.
