What is the agonist for scapular protraction?

What is the agonist for scapular protraction?

The agonist at scapulothoracic joint was set as the serratus anterior because scapular protraction is by shoulder internal rotation.

What is the agonist in scapular elevation?

agonistic: latissimus dorsi, lower trapezius, middle trapezius, teres minor, posterior deltoid. antagonistic: anterior deltoid, middle deltoid, pectoralis major, pectoralis minor, infraspinatus, levator scapulae.

What muscles protract the scapula?

The rhomboideus and the levator scapulae muscles also retract and elevate the scapula. Acting antagonistically to these muscles, the pectoralis minor and the serratus anterior protract the scapula forward, as when a person reaches for something.

What are the agonist and antagonist muscles in shoulder flexion?

Agonist is deltoid, antagonist is the latissimus dorsi. As the muscles contract across the shoulder joint it brings your shoulder upward into flexion as you push the ball the opposite happens and the antagonist becomes your deltoid and the latissimus dorsi becomes your agonist. Gives you the force to push the ball.

What is the antagonist of the pectoralis major?

Pectoralis major
Antagonist Deltoid muscle, Trapezius
Latin Musculus pectoralis major
TA98 A04.4.01.002

What is the antagonist to the pectoralis major?

What muscles elevate depress retract and protract the scapula?

The trapezius elevates, depresses, and retracts the scapula. The descending muscle fibers of the trapezius muscle internally rotate the arms. The transverse muscle fibers retract the scapulae, and the ascending muscle fibers medially rotate the scapulae.

When the shoulder blades are retracted which muscle is the antagonist?

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. Used together, they fix the scapula in space to provide a fulcrum from which to move the (lever) arm.

What are the antagonist muscles of the shoulder?

Pectoralis major and latissimus dorsi act as antagonists. The middle region of the deltoid muscle is the prime mover for arm abduction. The pectoralis major acts as an antagonist to the middle deltoid anteriorly, whilst the latissimus dorsi acts as the antagonist posteriorly.

What is the antagonist of the Iliacus?

Iliacus muscle
Antagonist Gluteus maximus
Latin Musculus iliacus
TA98 A04.7.02.003

How do you name the agonist and antagonist during scapular depression?

Name the agonist and antagonist during scapula downward (medial) rotation. agonist: levator scapula. antagonist: upper trapezius. Name the agonist and antagonist during scapular depression. agonist: lower trapezius. antagonist: upper trapezius.

Which muscle is the agonist and the antagonist?

The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. One way to remember which muscle is the agonist – it’s the one that’s in ‘agony’ when you are doing the movement as it is the one that is doing all the work.

What are the antagonist and neutralizers of the triceps?

Antagonist: Mid traps, rhomboids Neutralizers: Upper and lower trapezius muscle acts to prevent downward rotation, and the lower trapezius muscles act to prevent elevation, and downward rotation. Stabilizers: Serratus anterior, rhomboids, levator scapulae

What is the prime mover and antagonist of the shoulder?

Shoulder Horizontal Adduction (Horizontal Flexion) Prime Mover: Pectoralis major. Synergists: Anterior deltoid. Antagonists: Posterior deltoid. Neutralizers: Posterior deltoid, infraspinatus, and teres minor neutralize internal rotation force created by the anterior deltoid and pectoralis major.
