Question 2

Antagonist

Answer 2

• The muscle that opposes the movement caused by a prime mover.
• It relaxes and lengthens in a controlled way to ensure movement is performed smoothly by the prime mover.

Question 3

Answer 3

The lack of muscle tone.

Question 4

Atrophy

Answer 4

The wasting away of muscles.

Question 5

Contractility

Answer 5

The ability of muscles to contract and shorten.

Question 6

Elasticity

Answer 6

The ability of muscles to return to their original shape after contracting or extending.

Question 7

Extensibility

Answer 7

The ability of the muscles to extend and lengthen.

Question 8

Fatigue (of muscles)

Answer 8

A muscle’s inability to respond to stimulus or maintain contractions.

Question 9

Fixators

Answer 9

Muscles that stabilise the bone of the prime mover’s origin so that it can act efficiently (stabilisers).

Question 10

Tone (tonus)

Answer 16

The partial contraction of a resting muscle.

Agonist

Answer 17

The muscle responsible for causing a movement (prime mover).
