Answer 0

Refers to specific locations of landmark in the body

Question 1

Biomechanics

Answer 1

The science concerned with the internal and external force acting upon the body and the effects produces by these forces

On the front of the body

Question 7

Posterior (or dorsal)

Answer 7

On the back of the body

Question 8

Answer 8

Positioned near the middle of the body

Question 9

Lateral

Answer 9

Positioned toward the outside

Question 10

Contralateral

Answer 10

On the opposite side of the body

Question 11

Ipsilateral

Answer 11

On the same side of the body

Question 12

Anatomic positions

Answer 12

The body is standing erect with the arms at the side and the palms forward

Question 13

What are the 3 planes of motion

Answer 13

Sagittal - imaginary bisector that divides the body into right and left halves
Frontal - imaginary bisector that divides the body into front and left halves
Transverse - a imaginary bisector divides the body into top and bottom halves

Question 14

Flexion

Answer 14

A bending motion in which the relative angle between two adjacent segment decreases

Question 15

Extension

Answer 15

A straightening movement in which the relative angle between two adjacent segment increases

Question 16

Hyperextension

Answer 16

The extension of a joint beyond its normal range or limit

Question 17

Abduction

Answer 17

Movement in the frontal plane toward the midline of the body

Question 18

Adduction

Answer 18

Movement in the frontal plane away from the midline of the body

Question 19

Internal Rotation

Answer 19

Rotation of a joint toward the middle of the body

Question 20

External rotation

Answer 20

Rotation of a joint away from the middle of the body

Question 21

Horizontal abduction

Answer 21

Movement in the transverse plane from an anterior position to a lateral position

Question 22

Horizontal adduction

Answer 22

Movement of the arm or thigh in the transverse plane from a lateral position to an anterior position

Question 23

Scapular retraction

Answer 23

Adduction of scapula; shoulder blades move toward the midline.

Question 24

Scapular protraction

Answer 24

Adduction of scapula; shoulder move toward away from the midline

Question 25

Scapular depression

Answer 25

Downward (inferior) motion of scapula

Question 26

Scapular elevation

Answer 26

Upward (superior) motion of scapula

Question 27

What are the three primary time of muscle action?

Answer 27

``` Isotonic (constant muscle tension) - eccentric - concentric Isometric (constant muscle length) Isokinetic (constant velocity of motion) ```

Question 28

Isotonic muscle action

Answer 28

Force is produced, muscle tension is developed, movements occurs through a given range of motion

Question 29

Eccentric muscle action

Answer 29

Muscle develops tension while lengthening

Question 30

Concentric muscle action

Answer 30

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

Question 31

Isometric muscle action

Answer 31

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

Question 32

Isokinetic muscle action

Answer 32

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