Chapter 5

Question 1

Motor behavior

Answer 1

Motor response to internal and external environment stimuli

Question 2

Inferior

Answer 2

Position below a reference point

Question 3

Isokinetic

Answer 3

A muscle shortens at a constant speed over a full range of motion

Question 4

Lateral

Answer 4

Positioned toward the outside of the body

Question 5

Proximal

Answer 5

Nearest to the center of the body or point of reference

Question 6

Distal

Answer 6

Positioned farthest from the body or point of reference

Question 7

What is Concentric muscle contraction

Answer 7

Muscle shortens

Question 8

Motor control

Answer 8

How the nervous system integrates internal and external sensory info to produce a motor response

Question 9

Abduction

Answer 9

Away from the middle of the body

Question 10

Adduction

Answer 10

Toward the middle of the body

Question 11

What is the transverse plane of motion

Answer 11

Bisecting the body in top and bottom. Most injurieshappen in this plane ( any type of rotation . Any other time of clock)

Question 12

Second class lever

Answer 12

The output force is between the fulcrum and the input force like a wheel barrel

Question 13

Motor learning

Answer 13

Integration of motor control process through practice and experience

Question 14

what is Isometric contraction

Answer 14

Muscle length does not change( a hold like plank )

Question 15

First class lever

Answer 15

Have the fulcrum in the middle like a seesaw . The input force and output force are on opposite sides

Question 16

Third class lever

Answer 16

The input force is between the fulcrum and output force. Like the forearm in a dumbbell curl

Question 17

Medial

Answer 17

Positioned near the middle of the body

Question 18

what is the Sagittal plane of motion

Answer 18

Bisects the body into left and right halves. (Flexion and extension. 12 and 6 on the clock)

Question 19

What is the Frontal plane of motion

Answer 19

Bisects the body from front and back.(Lateral movement/abduction adduction . 3 and 9 on the clock)

Question 20

Anterior

Answer 20

On the front of body

Question 21

Superior

Answer 21

Positioned above a reference point

Question 22

Posterior

Answer 22

On the back of body

Question 23

What is a force couple

Answer 23

Muscle groups moving together to make movement around a joint. (Ex. Hamstrings,quads, and ass during a squat)

Question 24

Length tension relationship

Answer 24

The resting length of a muscle and the tension the muscle can make at this length

Question 25

What is eccentric muscle contraction

Answer 25

Muscles lengthens . Negative part of lift.
