Muscle

Question 1

What is the primary function of muscle tissue?

Answer 1

The primary function of muscle tissue is to produce movement.

Question 2

What are the three types of muscle tissue?

Answer 2

The three types of muscle tissue are skeletal, cardiac, and smooth.

Question 3

Which type of muscle tissue is striated and voluntary?

Answer 3

Skeletal muscle tissue is striated and voluntary.

Question 4

Which type of muscle tissue is found in the walls of hollow organs?

Answer 4

Smooth muscle tissue is found in the walls of hollow organs.

Question 5

Which type of muscle tissue is found in the heart?

Answer 5

Cardiac muscle tissue is found in the heart.

Question 6

True or False: Smooth muscle tissue is under voluntary control.

Answer 6

False. Smooth muscle tissue is involuntary.

Question 7

What is the basic functional unit of skeletal muscle?

Answer 7

The basic functional unit of skeletal muscle is the sarcomere.

Question 8

What is the role of myosin in muscle contraction?

Answer 8

Myosin is a protein that interacts with actin to generate the force of muscle contraction.

Question 9

What is the neurotransmitter responsible for muscle contraction at the neuromuscular junction?

Answer 9

Acetylcholine is the neurotransmitter responsible for muscle contraction at the neuromuscular junction.

Question 10

What is the term for the ability of muscle tissue to stretch without being damaged?

Answer 10

The term for the ability of muscle tissue to stretch without being damaged is extensibility.

Question 11

What is the term for the ability of muscle tissue to return to its original shape after being stretched?

Answer 11

The term for the ability of muscle tissue to return to its original shape after being stretched is elasticity.

Question 12

Which type of muscle tissue has intercalated discs?

Answer 12

Cardiac muscle tissue has intercalated discs.

Question 13

What is the specific type of smooth muscle found in blood vessels?

Answer 13

The specific type of smooth muscle found in blood vessels is vascular smooth muscle.

Question 14

What is the term for the ability of muscle tissue to generate tension and contract?

Answer 14

The term for the ability of muscle tissue to generate tension and contract is contractility.

Question 15

What is the term for the connective tissue that surrounds bundles of muscle fibers?

Answer 15

The connective tissue that surrounds bundles of muscle fibers is called perimysium.

Question 16

What is the term for the connective tissue that surrounds individual muscle fibers?

Answer 16

The connective tissue that surrounds individual muscle fibers is called endomysium.

Question 17

What is the term for the connective tissue that surrounds the entire muscle?

Answer 17

The connective tissue that surrounds the entire muscle is called epimysium.

Question 18

What is the term for the point of attachment of a muscle to a bone that remains relatively fixed during contraction?

Answer 18

The point of attachment of a muscle to a bone that remains relatively fixed during contraction is called the origin.

Question 19

What is the term for the point of attachment of a muscle to a bone that moves during contraction?

Answer 19

The point of attachment of a muscle to a bone that moves during contraction is called the insertion.

Question 20

What is the term for the type of muscle contraction where the muscle shortens and generates force?

Answer 20

The type of muscle contraction where the muscle shortens and generates force is called concentric contraction.

Question 21

What is the term for the type of muscle contraction where the muscle lengthens while generating force?

Answer 21

The type of muscle contraction where the muscle lengthens while generating force is called eccentric contraction.

Question 22

What is the term for the type of muscle contraction where the muscle length remains constant as it generates force?

Answer 22

The type of muscle contraction where the muscle length remains constant as it generates force is called isometric contraction.

Question 23

All muscle tissue has some degree of elasticity and extensibility, but which type of muscle tissue is capable of the greatest levels of these properties?
A. Cardiac B. Skeletal C. Smooth

Answer 23

C. Smooth
E.g the bladder and the stomach these organs are composed of smooth muscle and can extend/return back to it’s original shape
