What is protraction and retraction of shoulder?

Protraction of the scapula occurs when the shoulder is moved forward, as when pushing against something or throwing a ball. Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column.

What causes protracted scapula?

Scapular dyskinesis in impingement is characterized by loss of acromial upward rotation, excessive scapular internal rotation and excessive scapular anterior tilt. These positions create scapular protraction, which decreases the subacromial space and decreases demonstrated rotator cuff strength.

Which joint allows retraction and protraction?

sternoclavicular joint

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.

What is the function of scapula?

The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.

Why is scapular protraction important?

The muscle activation of the muscles surrounding the scapula and upper extremity muscles also increased after active scapular protraction. stated that the serratus anterior muscle plays the most important role in upward rotation as well as stabilization of the scapula.

What muscles are attached to the scapula?

The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process. The scapula provides attachment sites for many muscles including the pectoralis minor, coracobrachialis, serratus anterior, triceps brachii, biceps brachii, and the subscapularis.

Which muscle is not attached to the scapula?

What are the 3 processes of the scapula?

The scapula has three angles (superior/medial, lateral, inferior), three borders (medial, lateral/axillary, and superior), and two surfaces (ventral and dorsal). The scapula has three processes: the acromion, the spine, and the coracoid process.

What type of bone is scapula?

Flat Bones Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.

What does the scapula bone protect?

The scapula stabilizes the arm and neck The scapula, better known as the shoulder blade, is a triangular bone that serves as a joining force between the clavicle and the humerus. This bone is located posteriorly (on the back half of the body).

How does the scapula attach to the body?

The scapula is also known as the shoulder blade. It articulates with the humerus at the glenohumeral joint, and with the clavicle at the acromioclavicular joint. In doing so, the scapula connects the upper limb to the trunk. It is a triangular, flat bone, which serves as a site for attachment for many (17!)

These surgeries involve taking all or part of a nerve or muscle and moving it to another part of the body. Nerve and muscle transfers for scapular winging usually focus on the shoulder, back, or chest.
