Stabilizes a joint so that the prime mover can act at more distal joints?
synergist
What kind of muscle is a synergist?
The synergist muscle is a kind of muscle that performs or helps perform the same set of joint motion as the agonists. Synergist muscle acts on movable joints.
What is scapular protraction?
Scapular protraction is moving the scapula (shoulder blade) forward. The opposite is scapular retraction. To "feel" the definition, first try retraction -- pull your shoulders back to squeeze your shoulder blades together as if you're trying to hold a pencil between them. Now do the opposite -- that opposite movement is scapular protraction.
Is the scapular area is both dorsal and posterior?
Yes, the scapular area, i.e. the area of the shoulder blades, is both dorsal and posterior.
What postural muscles for the most part?
synergist
What are the prime movers of scapular elevation?
Levator scapulae and trapezius
What two muscles that protect the scapula?
Retraction= Middle trapezius Elevation= Upper trapezius
What muscle is used when shrugging your shoulders?
A number of muscles are involved in shrugging your shoulders, including the latissiumus dorsi, the deltoids, the rhomboids, the scapular muscles, the biceps, the triceps, among others. The primary muscle is the upper trapezius muscle. The secondary muscles are the middle trapezius muscles and the levator scapulae.
What is the difference in normal and abnormal scapulohumeral rhythm?
In abnormal scapulo humeral rhthym, there is excess scapular movt, excess upper trapezius movts, winging of scapula and forward scapular movt may be noticed.
What is the prime mover the synergist and the antagonist for a pull up?
synergists: trapezius, teres major and minor, flexors, biceps brachiiantagonists: deltoid, extensors, triceps brachii
What is shoulder elevation?
Shoulder elevation refers to the movement of raising the shoulders towards the ears. It primarily involves the contraction of the upper trapezius muscles. Shoulder elevation is commonly seen in movements such as shrugging or lifting heavy objects.
What muscle acts as synergist to trapezius in shoulder retraction?
the muscle is used when you eat to much crispey skin chicken from the tea house and you jam tart out self lol :P
Which of these phrases most aptly describes muscle insertion?
The phrase tendon attachment that moves most aptly describes muscle insertion. The trapezius muscle inserts on the acromion and scapular.
What is the intended action of the trapezius in a barbell shrug?
Elevation, depression, and retraction of scapula. Upper is also involved in extension of the head.
What muscle moves the scapula forward and rotates scapula upward?
You can't have one muscle that both elevates AND depresses a bone. So your question is a little confusing, Upward rotation: Serratus anterior, Upper and lower fibers of trapezius Retraction (adduction): Middle fibers of trapezius, rhomboid major and minor Elevation: Upper fibers of trapezius, levator scapulae, rhomboid major and minor Depression: Lower fibers of trapezius Let me know if I left any out but this should be all of them! Trevor .............................. the above answer is incomplete........ The trapezius is antagonist to itself, in that it can both elevate and depress the scapula
What muscles is responsible for the movement of scapula depression?
The movement of the scapula is largely determined by the position of the shoulder girdle as a whole. As a "floating bone" the scapula is often at the mercy of the more fixed extremities and can be acted upon by several different muscles simultaneously. That being said, the prime mover responsible for scapular depression is the trapezius (specifically the lower fibers). Other muscles which act as stabilizers or synergists in scapular depression and eventual scapular protraction are the subscapularis, the serratus anterior and the lower fibers of latissimus dorsi.
What are the antagonists of the shoulder girdle at Upward rotation?
The Trapezius muscles are involved in upward rotation of the scapula. However Trapezius is agonist/antagonist to itself as the upper portion elevates the scapula, the middle portion adducts the scapula and the lower portion depresses the scapula, while all parts are involved in upward rotation of the scapula. The Serratus Anterior assists in rotating the scapula (glenoid fossa) upward, (which would make it a synergist with the trapezius). The Serratus Anterior is antagonist to the upper and middle portions of Trapezius, so we are back to the agonist /antagonist relationship of the traps. That's about all I can contribute to this question.
