What muscle does 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.

Beside this, what is scapular protraction?

Protraction of the scapula is sometimes called abduction of the scapula. The scapula is moved laterally and anteriorly along the chest wall. Muscles: serratus anterior is the prime mover. Retraction of the scapula is sometimes called adduction of the scapula.

Furthermore, what muscles cause scapular upward rotation? The serratus anterior and upper and lower trapezius muscles are the primary stabilizing synergists which produce upward scapular rotation and posterior tilt, whereas the rhomboids, levator scapulae, and pectoralis minor muscles are responsible for downward scapular rotation and anterior tilt.

Correspondingly, what is protraction and retraction?

Retraction/Protraction/Depression/Elevation. Scapular retraction refers to moving the shoulder blades (scapula) towards the spine. The opposite is protraction – moving the shoulder blades away from the spine. If you try to pinch your shoulder blades all the way together they will retract.

Which muscles attach 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.

What causes scapular depression?

The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles. Depression is accomplished through the force of gravity and the actions of the latissimus dorsi, serratus anterior, pectoralis major and minor, and the trapezius muscles.

What is the main function of the scapula?

The scapula stabilizes the arm and neck The scapula plays an important role in stabilizing the other bones involved in the rhythm of shoulder motion. Many muscles are located in the area of the shoulder girdle, including rotator cuff muscles, nerve networks such as the brachial plexus, and upper arm muscles.

Why is scapular retraction important?

Why is scapular retraction important? Being able to retract your scapula is important because protracted scapulae make it difficult to move your shoulder joints well. Protracted scapulae can make it very difficult to stand up straight because the weight of your arms is dragging your thoracic spine into kyphosis.

What muscles pull the scapula down?

To achieve the correct scapular position, you need to use your mid and lower trapezius muscles to retract the shoulder and pull the scapula down medially.

How does the scapula work?

The scapula, commonly referred to as the shoulder blade, is the bone that sits above the rib cage in the upper back. It creates the shoulder joint where it meets with the head of the humerus—the bone of the upper arm. The scapulae can move in six directions and each movement is produced by specific, primary muscles.

How do you strengthen your rhomboids?

These five exercises help strengthen the rhomboid muscles and improve your posture.

1. Prone lateral raise. Lie flat on your stomach on a mat or bench.
2. Front raise thumbs up. Lie down on your stomach on a mat or bench with your forehead resting down.
3. Scapular retraction.
4. Rear delt flys.
5. Scapular wall slides.

What is an example of protraction?

Protraction is movement of a body part in the anterior direction, i.e. being drawn forwards. The movement of protraction is the opposite of the movement of retraction. The only joints capable of protraction are the shoulder joint and the jaw.

Is protraction the same as abduction?

Scapular Abduction - Also called scapular flexion or protraction. A movement where the scapula moves laterally away from the spinal column. Scapular Adduction - Also called scapular extension or retraction. It is a movement the opposite of abduction.

What is elevation and depression in anatomy?

Depression and elevation are downward and upward movements of the scapula or mandible. The upward movement of the scapula and shoulder is elevation, while a downward movement is depression. These movements are used to shrug your shoulders.

What does retraction mean in anatomy?

Short definition of Retraction (in the context of a term to describe movement of the body): Retraction is movement of a body part in the posterior direction, i.e. being drawn backwards. The movement of retraction is the opposite of the movement of protraction.

What plane of motion is protraction?

transverse plane

What does opposition mean in anatomy?

joints. In joint: Sellar joint. This movement is called opposition (i.e., of thumb to fingers). During opposition the thumb is rotated around its long axis; it has been said that human civilization depends upon the opposition of the thumb.

What is elevation in anatomy?

Definition of elevation in the context of movement of the body: Elevation is the upward movement of structures of the body. For example, elevation of a shoulder joint raises the corresponding arm vertically upwards, rather than outwards, to the side or in any other direction.

Which region of the body allows for retraction and protraction?

Protraction and retraction (and protrusion and retrusion) Protraction and retraction occur in two major regions of the body – the scapula and the mandible. Protraction refers to protruding or sticking out. Retraction refers to bringing together.

What is adduction anatomy?

In medicine and biomechanics, movements of limbs and other body parts toward or away from the center line of the body (a line that runs up and down the center of the human body) are termed adduction and abduction, respectively. Adduction is the movement of a body part toward the body's midline.

What is upward rotation of scapula?

Results. The middle and lower serratus anterior muscles produce scapular upward rotation, posterior tilting, and external rotation. Upper trapezius produces clavicular elevation and retraction. The lower trapezius assists in medial stabilization and upward rotation of the scapula.

What muscles do external rotation of shoulder?

The prime muscle groups that externally rotate the glenohumeral joint are the posterior deltoid, infraspinatus, and teres minor.
