Answer 3

positioned below a point of reference

Question 4

Proximal

Answer 4

positioned nearest the center of the body or point of reference

Question 5

distal

Answer 5

positioned farthest from the center of the body or point of reference

Question 6

anterior/ventral

Answer 6

on the front of the body

Question 7

posterior/dorsal

Answer 7

on the back of the body

Question 8

medial

Answer 8

positioned near the middle of the body

Question 9

lateral

Answer 9

positioned toward the outside of the body

Question 10

contralateral

Answer 10

positioned on the opposite side of the body

Question 11

ipsilateral

Answer 11

positioned on the same side of the body

Question 12

anatomic position

Answer 12

the position with the body reect with the arms at the sides and palms forward used for a place of reference

Question 13

Sagittal Plane

Answer 13

an imaginary bisector that divides the body into left and right halves – Parallel/ Front to Back Movements

Question 14

Flexion

Answer 14

bending movement in which the relative angle between two adjacent segments decreases

Question 15

Extension

Answer 15

straightening movement in which the relative angle between two adjacent segments increases.

Question 16

Frontal Plane

Answer 16

divides the body into front and back halves – Side to Side Movements

Question 17

abduction

Answer 17

movement away from the midline of the body

Question 18

adduction

Answer 18

moving towards the midline of the body.

Question 19

Transverse Plane

Answer 19

divides between upper and lower/top and bottom halves – Rotational Movements

Question 20

Primary Muscle Actions

Answer 20

Isontonic
Isometric
Isokinetic

Question 21

Isotonic

Answer 21

Force is produced. Muscle Tension is developed. Movement occurs. Two Phases: Eccentric and Concentric

Question 22

Isometric

Answer 22

Contractile Force equals resistive force. Dynamically stabilizes the body

Question 23

Isokinetic

Answer 23

Requires sophisticated equipment. Fixed speed of movement. Resistance varies with force exerted.

Question 24

Eccentric Muscle Action

Answer 24

The Negative portion of an exercise.When a muscle develops tension while lengthening. Prevents the resistance from accelerating downward uncontrollably

Question 25

Isometric Muscle Action

Answer 25

When a muscle is exerting force equal to the force being placed on it leading to no visible change in muscle length

Question 26

Isokinetic Muscle Action

Answer 26

When a muscle shortens at a constant speed over the full range of motion

Question 27

Concentric Muscle Action

Answer 27

When a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle

Question 28

Motor Learning

Answer 28

Leads to a permanent change in the capacity to produce skilled movements

Question 29

Proprioception

Answer 29

Using information from mechanoreceptors to sense position and limb movements

Question 30

Motor Control

Answer 30

Integrating sensory information with past experiences to produce a response

Question 31

Motor Development

Answer 31

change in motor skill behavior over time
