You protract by pushing your shoulders forward and spreading your scapulae across your back, trying to touch them in front of your chest. … In retraction, the scapulae move towards the spine and towards each other.
What causes 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.
What is protraction exercise?
Drive the heels of your hands into the wall, flattening your shoulder blades against your back. Your neck should remain long so ensure you do not hunch your shoulders up. Hold this position, relax and then repeat. Ensure you do not bend your arms at any point during this exercise.

What is an example of adduction?
Adduction is the movement of a body part toward the body’s midline. So, if a person has their arms straight out at the shoulders and brings them down to their sides, it is adduction. … Closing arms to the chest or bringing knees together are other examples of adduction.

Is dorsiflexion a flexion or extension?
Dorsiflexion and plantar flexion refer to extension or flexion of the foot at the ankle. These terms refer to flexion in direction of the “back” of the foot, which is the upper surface of the foot when standing, and flexion in direction of the sole of the foot.What is the difference between plantar flexion and dorsiflexion?
Dorsiflexion and plantar flexion are movements at the ankle joint, which is a hinge joint. Lifting the front of the foot, so that the top of the foot moves toward the anterior leg is dorsiflexion, while lifting the heel of the foot from the ground or pointing the toes downward is plantar flexion.
What joints can perform 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. “Protraction of the shoulder is one of the movements used in rowing”. The only joints capable of protraction are the shoulder joint and the jaw.
Article first time published onWhy is serratus anterior important?
Serratus Anterior is a key muscle for keeping healthy function of the shoulder and plays a pivotal role in preventing neck pain and shoulder injuries. Just using stretches, massage and treatment for the area in pain will achieve little result. As will just trying to strengthen with isolated exercises.
What does serratus mean?
Serratus: One of several muscles of the back and thorax. that have interdigitating slips that ressemble the notches on the cutting edge of a saw. (Serrated refers to a finely notched edge.)
Does serratus anterior depress the scapula?
Function. The contraction of the entire serratus anterior leads to a anterolateral movement of the scapula along the ribs. … In contrast, the superior part depresses the scapula and thus acts antagonistically. Another function of the serratus anterior is the active stabilization of the scapula within the shoulder.

This guide will help you establish a morning, night, and sitting routine that benefits your posture and body as a whole,” says Marina Mangano, founder of Chiro Yoga Flow.
Is protraction and abduction the same thing?
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 muscles do shoulder adduction?
Adduction is accomplished primarily by the pectoralis major, latissimus dorsi, teres major, triceps, and coracobrachialis. The deltoid and the supraspinatus, a muscle that runs along the scapula in the back, are the two main abductors of the shoulder.
What is Triangle auscultation?
The triangle of auscultation is a relative thinning of the musculature of the back, situated along the medial border of the scapula which allows for improved listening to the lungs.
What is mandible protraction?
Movements of the mandible For the mandible, protraction occurs when the lower jaw is pushed forward, to stick out the chin, while retraction pulls the lower jaw backward.
What are two characteristics of protraction?

- Depressing the jaw at the temporomandibular joint.
- Elevating the jaw at the temporomandibular joint.
What is difference between abduction and adduction?
Abduction vs Adduction Abduction is the motion that happens when the body moves away from the centreline. Adduction is the motion when the body moves towards the centerline.
What adduction means?
Adduction: Movement of a limb toward the midline of the body. The opposite of adduction is abduction.

What joint does dorsiflexion and Plantarflexion?
Overview. The ankle joint is a hinged synovial joint with primarily up-and-down movement (plantarflexion and dorsiflexion). However, when the range of motion of the ankle and subtalar joints (talocalcaneal and talocalcaneonavicular) is taken together, the complex functions as a universal joint (see the image below).
What are the 10 body movements?

- abduction – adduction.
- circumduction (no opposite)
- elevation – depression.
- internal/medial rotation – external/lateral rotation.
- dorsiflexion – plantar flexion.
- pronation – supination.
- inversion – eversion.
What are the 5 types of muscle movements?

What is foot eversion?
Foot eversion is when your foot collapses inward, usually with your feet also flattening. The sole of the foot actually faces away from your other foot, increasingly so as the problem worsens. … Many people think foot eversion is normal; it is not.
What is the difference between protraction and retraction?

During protraction, the scapulae move away from the spine as you round the upper back (thoracic spine). … In retraction, the scapulae move towards the spine and towards each other. Retracting is done by squeezing the shoulder blades together.
What plane is scapular protraction?
