topic 4.2 quiz

Question 1

flexion

Answer 1

a bending movement around a joint in a limb (as the knee or elbow) that decreases the angle between the bones of the limb at the joint

Question 2

extension

Answer 2

a physical position that increases the angle between the bones of the limb at a joint

Question 3

abduction

Answer 3

any motion of the limbs or other body parts that pulls away from the midline of the body

Question 4

adduction

Answer 4

the movement of a body part toward the body’s midline

Question 5

medial rotation

Answer 5

the movement of a limb or muscle group toward the center of the body

Question 6

lateral rotation

Answer 6

the movement of a body part or muscle group away from the center of the body and around the longitudinal axis of a bone

Question 7

pronation

Answer 7

a rotational movement of the forearm that results in the palm facing posteriorly

Question 8

supination

Answer 8

rotation of the forearm and hand so that the palm faces forward or upward

Question 9

elevation

Answer 9

movement in a superior direction

Question 10

depression

Answer 10

movement in a downward direction

Question 11

rotation

Answer 11

circular movement of a joint or muscle that allows body to move in circular manner

Question 12

circumduction

Answer 12

multiple active muscles performing different synchronous ranges of motion

Question 13

dorsi flexion

Answer 13

backward bending and contracting

Question 14

plantar flexion

Answer 14

extension of ankle so that foot points down and away

Question 15

eversion

Answer 15

the movement of the sole of the foot away from the median plane

Question 16

inversion

Answer 16

a movement in which the plantar surface (sole) of the foot rotates towards the mid-line of the body

Question 17

isotonic

Answer 17

constant tension/constant movement. holding weight at the maximum amount possible

Question 18

isometric

Answer 18

(static) muscle does not move, the muscle is static/stationary, contracted with no movement

Question 19

isokinetic

Answer 19

constant speed and movement, repeated movement at a constant speed

Question 20

concentric

Answer 20

muscle shortens as it is generating force

Question 21

eccentric

Answer 21

muscle lengthens as it is generating force

Question 22

agonist

Answer 22

prime movers generates the movement, arm down = tricep flexing

Question 23

antagonist

Answer 23

muscle that contracts eccentrically, arm up = tricep is stretching

Question 24

doms result

Answer 24

Eccentric muscle action and muscle damage. Overstrecthing and overtraining

Question 25

doms prevention

Answer 25

Reducing the eccentric component of muscle actions during early training. Starting at a lower intensity and gradually increasing
