Muscle Actions definitions Flashcards

The main muscle responsible for a movement, such as the biceps brachii during elbow flexion.

Another term for agonist, the primary muscle driving a specific movement.

A muscle that opposes the action of the agonist, like the triceps brachii during elbow flexion.

A muscle that aids the prime mover, enhancing the movement, such as the brachialis assisting the biceps brachii.

A muscle that stabilizes the origin of the prime mover, ensuring effective movement, like the rotator cuff stabilizing the humerus.

A major muscle of the upper arm, acting as the agonist during elbow flexion.

A muscle located at the back of the arm, acting as the antagonist during elbow flexion.

A muscle that works as a synergist to the biceps brachii during elbow flexion.

A group of muscles on the scapula that stabilize the humerus during arm movements.

A movement involving bending the arm at the elbow, primarily driven by the biceps brachii.

The process by which a muscle shortens, causing movement at a joint.

The fixed attachment point of a muscle, which does not move during contraction.

The movable attachment point of a muscle, which moves during contraction.

The bone of the upper arm, stabilized by the rotator cuff during certain movements.

The shoulder blade, serving as the origin for the rotator cuff muscles.
