Secreting hormones

Question 2

Which property of muscle tissue allows it to return to its original length after being stretched?

Accepted Answer

Elasticity

Question 3

The connective tissue layer that surrounds individual muscle fibers is called:

Accepted Answer

Endomysium

Question 4

Which structure is formed by the merging of collagen fibers from the epimysium, perimysium, and endomysium at the end of a muscle?

Accepted Answer

Tendon

Question 5

A muscle fascicle is best described as:

Accepted Answer

A bundle of muscle fibers surrounded by perimysium

Question 6

Which of the following correctly matches the connective tissue layer with its function?

Accepted Answer

Perimysium: surrounds muscle fiber bundles (fascicles)

Question 7

Which of the following is a stem cell found in the endomysium that aids in muscle repair?

Accepted Answer

Myosatellite cell

Question 8

If a patient suffers an injury that damages the perimysium, which of the following structures is most likely affected?

Accepted Answer

Muscle fascicles

Question 9

Which of the following statements about the organization of skeletal muscle is TRUE?

Accepted Answer

Nerves are present in both the perimysium and endomysium

Question 10

A muscle contraction is initiated when a sudden change in membrane potential occurs in which structure?

Accepted Answer

Sarcolemma

Question 11

Which equation best represents the conversion of creatine phosphate (CP) to ATP in muscle cells?

Accepted Answer

$\mathrm{CP} + \mathrm{ADP} \rightarrow \mathrm{Creatine} + \mathrm{ATP}$

Question 12

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

Accepted Answer

Excitability

Question 13

Which connective tissue layer is directly connected to deep fascia and separates muscle from surrounding tissues?

Accepted Answer

Epimysium

Question 14

Which of the following best describes the relationship between muscle tension and load during isotonic concentric contraction?

Accepted Answer

Muscle tension exceeds the load

Question 15

Which structure in skeletal muscle is responsible for transmitting action potentials from the sarcolemma into the cell interior?

Accepted Answer

T tubule

Question 16

Which of the following is the correct order of connective tissue layers from outermost to innermost in a skeletal muscle?

Accepted Answer

Epimysium, Perimysium, Endomysium

Question 17

A patient with a genetic defect in the production of collagen would most likely have problems with which muscle structure?

Accepted Answer

Epimysium, Perimysium, and Endomysium

Question 18

Which of the following statements about muscle tissue is FALSE?

Accepted Answer

Smooth muscle is striated and multinucleated

Question 19

Which of the following best explains why skeletal muscle fibers are multinucleated?

Accepted Answer

They develop by fusion of embryonic myoblasts

Question 20

Which of the following is a real-world consequence of damage to the endomysium in skeletal muscle?

Accepted Answer

Impaired repair of muscle fibers due to loss of myosatellite cells
