chapter 10 anatomy

Front

What type of muscle contraction involves the generation of muscle force with constant muscle tension and a change in muscle length?

Back

Isotonic contractions.

Front

What is the term for the ability of a muscle to return to its original resting length after being stretched?

Back

Elasticity.

Front

If the biceps are the agonist, which muscle acts as the antagonist?

Back

Triceps.

Front

What type of muscle fibers are red in color and are known for their endurance capabilities?

Back

Type I muscle fibers.

Front

What does contractility refer to in muscle physiology?

Back

The ability of muscle to shorten and produce tension at its ends.

Front

What is the primary function of skeletal muscle?

Back

To facilitate movement by contracting and exerting force on bones.

Front

What is the difference between isotonic and isometric contractions?

Back

Isotonic contractions involve a change in muscle length with constant tension, while isometric contractions involve muscle tension without a change in length.

Front

What are the two main types of muscle fibers?

Back

Type I (slow-twitch) and Type II (fast-twitch) muscle fibers.

Front

What is the role of the agonist muscle during movement?

Back

The agonist muscle is the primary muscle responsible for producing a specific movement.

Front

What is the role of the antagonist muscle during movement?

Back

The antagonist muscle opposes the action of the agonist, helping to control movement and maintain balance.
