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 retraction means?
: the act of moving something back into a larger part that usually covers it : the act of retracting something. See the full definition for retraction in the English Language Learners Dictionary. retraction. noun. re·trac·tion | \ ri-ˈtrak-shən \
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 are the 3 major types of joints?
The structural classification divides joints into fibrous, cartilaginous, and synovial joints depending on the material composing the joint and the presence or absence of a cavity in the joint. The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses.
Which type of joint is the most movable?
Synovial jointsSynovial joints ( diarthroses ) are the most movable joints of the body and contain synovial fluid.
What are the 5 types of muscle movements?
Flexion and Extension. Flexion and extension are movements that take place within the sagittal plane and involve anterior or posterior movements of the body or limbs. … Abduction and Adduction. … Circumduction. … Rotation. … Supination and Pronation. … Dorsiflexion and Plantar Flexion. … Inversion and Eversion. … Protraction and Retraction.More items…
Which are the only two joints that can perform Circumduction Why?
Which are the only two joints that can perform circumduction? Why? Shoulder/ Hip – Ball and socket. What muscle is being used as you straighten out from a pike dive?
What muscles cross both the hip and knee joints?
The rectus femoris muscle crosses both the hip and the knee joint. Muscle contracture can be demonstrated by noting movement at one joint as the muscle is stretched at the other.
Which joints can Circumduct?
Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions. Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.
What is the difference between protraction and retraction?
Protraction and Retraction 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 are the 3 classifications of joints?
Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis).
Which body part is capable of retraction?
The only joints capable of retraction are the shoulder joint and the jaw.
What is shoulder protraction and retraction?
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 joint allows a gliding movement?
Planar jointsPlanar joints have bones with articulating surfaces that are flat or slightly curved faces. These joints allow for gliding movements, and so the joints are sometimes referred to as gliding joints.
Which of the following describes protraction and retraction?
lifting up a body part. Which of the following best describes depression? … protraction refers to the forward movement of a body part, and retraction to the backward movement of a part.
What muscles do shoulder retraction?
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 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.
