Question 1

Which of the following best describes the function of the perimysium in skeletal muscle anatomy?

Accepted Answer

It surrounds fascicles, which are groups of muscle fibers, with fibrous connective tissue.

Question 2

A patient suffers a deep laceration that severs the epimysium but leaves the perimysium and endomysium intact. Which of the following is most likely to be affected?

Accepted Answer

The structural integrity of the entire muscle as an organ.

Question 3

Which of the following statements about muscle tissue types is correct?

Accepted Answer

Skeletal muscle is voluntary and striated.

Question 4

A muscle attaches to two bones. The attachment to the less movable bone is called the:

Accepted Answer

Origin

Question 5

Which connective tissue sheath is most directly responsible for allowing nerves and blood vessels to reach individual muscle fibers?

Accepted Answer

Endomysium

Question 6

During a muscle contraction, which of the following best describes the relationship between the origin and insertion?

Accepted Answer

The insertion moves toward the origin.

Question 7

Which of the following is NOT a characteristic shared by all muscle tissue types?

Accepted Answer

Voluntary control

Question 8

A muscle is attached to bone via a broad, sheetlike connective tissue. This type of attachment is called:

Accepted Answer

Aponeurosis

Question 9

Which of the following best explains why skeletal muscle fibers require a rich blood supply?

Accepted Answer

To supply oxygen and nutrients and remove metabolic wastes rapidly.

Question 10

A muscle is attached to bone by a direct (fleshy) attachment. Which structure is involved in this type of attachment?

Accepted Answer

The epimysium fuses directly with the periosteum of the bone.

Question 11

Which of the following is a function of muscle tissue that is especially important for maintaining homeostasis during cold exposure?

Accepted Answer

Generating heat as they contract

Question 12

Which of the following best describes the order of connective tissue sheaths from outermost to innermost in a skeletal muscle?

Accepted Answer

Epimysium, perimysium, endomysium

Question 13

Which of the following scenarios best illustrates the function of contractility in muscle tissue?

Accepted Answer

A muscle fiber shortens forcibly when stimulated by a nerve impulse.

Question 14

A muscle that is unable to recoil to its resting length after being stretched is most likely deficient in which property?

Accepted Answer

Elasticity

Question 15

Which of the following is a unique feature of skeletal muscle compared to cardiac and smooth muscle?

Accepted Answer

It is under voluntary control.
