What is an agonist?

• A muscle that performs a specific movement by contracting.

• A muscle that causes the opposite movement.

• A muscle that stabilizes the joint.

• A muscle that assists the agonist.

What is an antagonist?

• A muscle that performs a specific movement by contracting.

• A muscle that causes the opposite movement.

• A muscle that stabilizes the joint.

• A muscle that assists the agonist.

What is Hering's Law of Equal Innervation?

• Both eyes receive equal innervation for their movements.

• One eye receives more signals than the other.

• Both eyes move independently.

• Only one eye is responsible for movement.

What are yoke muscles?

• Muscles of both eyes that work together to enable movement.

• Muscles that only work in one eye.

• Muscles that stabilize the head.

• Muscles that are inactive during eye movement.

What is convergence?

• Movement of both eyes inward.

• Movement of both eyes outward.

• Movement of one eye only.

• Movement that stabilizes the image.

What is divergence?

• Movement of both eyes inward.

• Movement of both eyes outward.

• Movement of one eye only.

• Movement that stabilizes the image.

What is the effect of Sherrington's Law?

• Helps understand why paralysis of an eye muscle leads to deviations in eye position.

• Explains how both eyes move independently.

• Describes the role of yoke muscles.

• Indicates that both eyes receive equal signals.

What is an antagonist?

• The muscle that performs the main movement.

• The muscle that causes the opposite movement of the agonist.

• The muscle that works with the agonist to support a movement.

• A muscle on the same side of the body as the agonist.

What is a synergist?

• A muscle that performs the main movement.

• A muscle that causes the opposite movement of the agonist.

• A muscle that works with the agonist to support a movement.

• A muscle on the opposite side of the body as the agonist.

What is an ipsilateral antagonist?

• A muscle that lies on the same side of the body as the agonist but performs the opposite movement.

• A muscle that lies on the opposite side of the body as the agonist.

• A muscle that supports the agonist's movement.

• A muscle that performs the main movement.
