Question 1

The muscle that contracts to produce a particular action is known as the _______.&#10;A) insertion&#10;B) origin&#10;C) agonist&#10;D) antagonist

Accepted Answer

The agonist muscle is the muscle responsible for producing a particular action by contracting. It works in opposition to the antagonist muscle, which lengthens or relaxes to allow for movement. The origins and insertions of muscles refer to their attachment points and do not indicate which muscle is contracting.

Question 2

_______ contraction occurs when muscles shorten and thicken.&#10;A) Isometric&#10;B) Motor&#10;C) Unconscious&#10;D) Isotonic

Accepted Answer

Isotonic contraction occurs when muscles shorten and thicken, while maintaining a constant tension. This is in contrast to isometric contraction (choice A), where tension is generated but there is no visible movement of the muscle. Motor (choice B) and unconscious (choice C) are not types of muscle contractions.

Question 3

_______ muscle is the voluntary muscle attached to bones.&#10;A) Smooth&#10;B) Skeletal&#10;C) Cardiac&#10;D) Active

Accepted Answer

Skeletal muscle is the voluntary muscle that is attached to bones and is responsible for locomotion and other movements of the body. Smooth muscle is involuntary and found in organs, while cardiac muscle is only found in the heart. "Active" is not a type of muscle.

Question 4

Each muscle is surrounded by a covering of connective tissue called _______.&#10;A) fibers&#10;B) epimysium&#10;C) fascicles&#10;D) perimysium

Accepted Answer

Epimysium is the connective tissue sheath that surrounds each muscle, providing support and helping to maintain the muscle's structure.

Question 5

The gastrocnemius muscle is located in the calf and is responsible for flexing the knee joint. It also assists with ankle plantar flexion.

Question 6

Excess acetylcholine is broken down by an enzyme called _______.&#10;A) ATP&#10;B) actin&#10;C) myosin&#10;D) acetylcholinesterase

Accepted Answer

Excess acetylcholine is broken down by an enzyme called acetylcholinesterase. It is responsible for terminating the action of acetylcholine by hydrolyzing it into its constituent molecules, acetic acid and choline, which can be recycled for further use.

Question 7

A muscle that extends the elbow is the _______.&#10;A) biceps brachii&#10;B) triceps brachii&#10;C) biceps femoris&#10;D) brachioradialis

Accepted Answer

The triceps brachii is the primary muscle responsible for extending the elbow joint. The biceps brachii, on the other hand, is responsible for flexing the elbow joint, while biceps femoris is a muscle involved in flexion of the knee joint, and the brachioradialis muscle assists in elbow flexion and supination of the forearm.

Question 8

Extensions of epimysium form tough cords of connective tissue, the _______, that anchor muscle to bones.&#10;A) ligaments&#10;B) fibers&#10;C) bone fragments&#10;D) tendons

Accepted Answer

Tendons are tough cords of connective tissue that anchor muscle to bones, and they are formed by extensions of the epimysium. Ligaments connect bones to bones, fibers can refer to any type of muscle fiber, and bone fragments are not a type of connective tissue that anchors muscle to bones.

Question 9
