Exam 2: Neuromuscular Fundamentals

The term "isokinetics" describes a type of dynamic exercise that uses concentric and/or eccentric muscle contractions.

The term "intrinsic" usually pertains to muscles within or belonging solely to the body part upon which they act.

When flexing all of the fingers joints maximally in combination with maximal wrist flexion and no further flexion of any of the involved joints may be reached, the result is _______.

Which of the following is true of an eccentric muscle action?

Which of the following is not true of an eccentric muscle action?

Antagonist muscles are known as prime or primary movers and are most involved in a joint action.

_____ is the ability of muscle to be passively stretched beyond its normal resting length.

Which of the following is not a true statement about antagonist muscles?

Each muscle in the human body may be innervated by a single nerve or multiple nerves.

Joint movement may occur without any muscle contraction.

The two major types of fiber arrangements are parallel and pennate.

Isotonic contractions are classified as concentric or eccentric on the basis of whether shortening or lengthening of the muscle occurs.

Contractility is the ability of muscle to contract and develop tension or internal force in the same direction as a resistive force when stimulated.

Which of the following does not result in the contraction of the muscle fibers in a particular motor unit?

_____ occurs when an antagonistic muscle becomes stretched to the point where it can no longer lengthen and allow movement.

Fusiform muscle fiber arrangement results in a circular pattern.

Which of the following pairs of muscles produces the strongest contractions?

Which of the following is a proprioceptor associated with muscle tissue?

Which of the following is a true statement about agonist muscles?

Which of the following is not a true statement of isokinetic exercise?
