Question 1

Which of the following best describes the role of collagen fibers in muscle tissue mechanics?

Accepted Answer

They do not resist compression but have very high tensile resistance, effectively transferring muscle tension to objects.

Question 2

A patient is unable to voluntarily move their arm after nerve damage. Which type of nerve fiber is most likely affected?

Accepted Answer

Somatic nerve fibers

Question 3

Which muscle tissue type is striated and under voluntary control?

Accepted Answer

Skeletal muscle

Question 4

During muscle contraction, which direction does the insertion move relative to the origin?

Accepted Answer

Insertion moves toward the origin

Question 5

Which property allows muscle tissue to return to its resting length after being stretched or shortened?

Accepted Answer

Elasticity

Question 6

Which of the following is NOT a function of skeletal muscle?

Accepted Answer

Secretion of digestive enzymes

Question 7

A muscle contraction occurs only when the tension generated by the muscle exceeds which of the following?

Accepted Answer

Resistance due to weight and friction

Question 8

Which prefix is commonly used to refer to muscle cells?

Accepted Answer

Myo-

Question 9

Which of the following statements about smooth muscle is correct?

Accepted Answer

It is non-striated and under involuntary control.

Question 10

Which connective tissue layer surrounds individual muscle fibers?

Accepted Answer

Endomysium

Question 11

If a drug blocks the function of visceral nerve fibers, which muscle types would be most affected?

Accepted Answer

Cardiac and smooth muscle

Question 12

Which of the following best explains why skeletal muscle fibers cannot contract without an intrinsic signal from the nervous system?

Accepted Answer

They require voluntary control via somatic nerve fibers.

Question 13

Which muscle tissue type is most likely to contract in response to autonomic nervous system input and is found in the walls of hollow organs?

Accepted Answer

Smooth muscle

Question 14

A person is able to walk and speak, but cannot control their heart rate or digestive motility. Which type of muscle tissue is responsible for the latter two functions?

Accepted Answer

Cardiac and smooth muscle

Question 15

Which of the following is a property shared by all muscle tissue types?

Accepted Answer

Ability to initiate and propagate electrical impulses

Question 16

Which connective tissue component is most important for providing resiliency and allowing muscle to return to its original length after stretching?

Accepted Answer

Elastic fibers

Question 17

Which of the following equations best represents the relationship required for muscle movement to occur?

Accepted Answer

$$Tension \u003e Resistance$$

Question 18

Which muscle tissue type is the major component of the heart myocardium?

Accepted Answer

Cardiac muscle

Question 19

Which of the following best describes the difference between voluntary and involuntary muscle movements?

Accepted Answer

Voluntary movements are consciously controlled, such as walking, while involuntary movements occur automatically, such as blood circulation.

Question 20

Which of the following is a real-world example of involuntary internal muscle movement?

Accepted Answer

Blood circulation
