Answer 7

Skeletal muscle

Question 8

In muscle, a bundle of what makes what, which then bundled will make what?

Answer 8

Muscle fibers, fascicle, and muscle

Question 9

What is a sheet of connective tissue that surrounds individual muscles, as well as groups of muscles with the same action?

Answer 9

Deep fascia

Question 10

What surrounds “individual” muscles, separating individual muscles?

Answer 10

Epimysium

Question 11

What surrounds the muscle fibers within a fascicle?

Answer 11

Endomysium

Question 11

What surrounds each fascicle and divides skeletal muscle into compartments?

Answer 11

Perimysium

Question 11

What fascicle orientation has fascicles that run parallel to the long axis of the muscle, tapered at both ends, strap, and has a high endurance but isn’t very strong?

Answer 11

Parallel

Question 12

What fascicle orientation is a sphincter, closes when they contract, and surrounds external body openings?

Answer 12

Circular

Question 13

What fascicle orientation’s direction of pull can be changed because different groups of fibers can be activated with a broad origin and narrow insertion?

Answer 13

Convergent

Question 14

What fascicle orientation has short fascicles, attach obliquely to a tendon or raphe, and stronger than a parallel fascicle of the same size?

Answer 14

Pennate

Question 15

What is an example of unipennate?

Answer 15

When muscle is attached to bone indirectly, what are the two ways it can be attached by?

Answer 17

Tendon and aponeurosis

Question 18

Are muscles in a single compartment normally innervated by one nerve or multiple?

Answer 18

One nerve

Question 19

Muscles in the same compartment tend to be what, which is that they do the same action?

Answer 19

Synergistic

Question 20

Muscles in opposite compartments tend to be what?

Answer 20

Antagonistic

Question 21

Acute compartment syndrome is from what or what, which can lead to tissue loss due to loss of blood supply?

Answer 21

Injury or accident

Question 22

Chronic compartment syndrome is caused by what?

Answer 22

Overuse

Question 23

When damaged muscle swells, the surrounding fascia constricts that puts pressure (pain) on the vessels and nerves and also prevents blood from entering or draining. What is this called?

Answer 23

Compartment syndrome

Question 24

Action, number or origins/heads, location of attachments, location of muscle, shape, relative size, and direction of fascicles and fibers is the ways to name what?

Answer 24

Muscles
