Muscle contractions

Question 1

concentric contraction

Answer 1

muscle shortens as force is being produced

Question 2

eccentric contraction

Answer 2

muscle lengthens when force is being produced. will slow the movement to allow for controlled movements.

Question 3

isometric contraction

Answer 3

Muscle contracts but there is no movement, muscle stays the same length

Question 4

muscle origin

Answer 4

the fixed point of attachment that is closer to the bodys midline.

Question 5

muscle insertion

Answer 5

Attached to the bone that moves most when the muscle contracts. Further from bodys midline.

Question 6

muscle contraction

Answer 6

The origin and insertion are drawn together, shortening the the muscle. Bones attached to the muscle produce movement in a specific direction. Called muslce action

Question 7

Agonist

Answer 7

muscle that casues the major action (prime mover)

Question 8

antagonist

Answer 8

muscle that relaxes and lengthens to allow movement to occur

Question 9

Synergist

Answer 9

Muscle that assists the agonist to produce the required movement

Question 10

Stabiliser

Answer 10

the group of muscles that ensure that the joint remains stable during the movement

Question 11

Reciprical inhibition

Answer 11

process of one muscle contracting (Agonist) whilst the other muscle relaxes (antagonist) to create movement
