Question 11

Occurs from decreased physical activity due to medical conditions or sedentary lifestyle

Answer 11

Disuse atrophy

Question 12

Innervations of skeletal muscles

Answer 12

Nerve trunk
Motor neurons
Sensory neurons
Sympathetic fibers

Question 13

Shortening of muscles

Answer 13

COntraction

Question 14

Lengthening of muscles

Answer 14

Relaxation

Question 15

Partial state of contraction of muscles while resting; accomplished by asynchronous discharge of nervous impulses.

Answer 15

Muscle tone

Question 16

The main muscle responsible for a specific movement (the prime mover)

Answer 16

agonist

Question 17

The muscle that opposes the action of the agonist

Answer 17

Antagonist

Question 18

T or F. As the agonist muscle contracts, the antagonistic muscle relaxes

Answer 18

T

Question 19

One or more muscles that steady the proximal part of a limb when a more distal part is being moved

Answer 19

Fixator

Question 20

Complements the contraction of the agonist, either by assisting with the movement generated by the agonist or by reducing the unnecessary movements that would occur as the agonist contracts

Answer 20

Synergist
