Answer 7

Near the middle of the body

Question 8

Lateral location

Answer 8

Toward the outside of the body

Question 9

Contralateral location

Answer 9

On the opposite side of the body

Question 10

Ipsilateral location

Answer 10

On the same side of the body

Question 11

Anatomic position

Answer 11

The position with the body erect with the arms at the sides and the Palm forward.
The position of reference for anatomic nomenclature.
The 3 planes of motion apply when in this position

Question 12

Sagittal plane

Answer 12

An imaginary bisect or that divides the body into left and right halves
Motion: flexion, extension, hyperextension

Question 13

Sagittal plane motions

Answer 13

Flexion
Bending movement in which the relative angle between two adjacent segments decreases
Extension
Straightening movement in which the relative angle between two adjacent segments increases
Hyperextension
Extension of a joint beyond the normal limit or range of motion

Question 14

Frontal plane

Answer 14

Imaginary bisect or that divides the body into front and back halves
Motions:
Abduction, adduction

Question 15

Frontal plane motion

Answer 15

Abduction:
Movement away from the midline of the body
Addiction:
Movement back toward the midline of the body

Question 16

Transverse plane

Answer 16

Imaginary bisector that divides the body into top and not town halves
Motion: internal rotation, external rotation, horizontal location, horizontal abduction, horizontal adduction

Question 17

Transverse plane motions

Answer 17

Internal/external rotation:
Rotation of a joint toward or away from the middle of the body
Horizontal abduction/addiction:
Movement if arm or thigh in the transverse plane from anterior to lateral or lateral to anterior position

Question 18

Scapular retraction

Answer 18

Adduction of scapular; shoulder blades move toward the midline

Question 19

Scapular protraction

Answer 19

Abduction of scapular; shoulder blades move away from the midline

Question 20

Scapular depression

Answer 20

Downward (inferior) motion of the scapula

Question 21

Scapular elevation

Answer 21

Upward (superior) motion of the scapula

Question 22

Eccentric muscle action

Answer 22

Eccentric muscle action occurs when a muscle develops tension while lengthening

Question 23

Concentric muscle action

Answer 23

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

Question 24

Isometric muscle action

Answer 24

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

Question 25

Isokinetic muscle action

Answer 25

Muscle shortens at a constant speed over the full range of motion

Question 26

Force

Answer 26

Influence applied by one object to another, which results in an acceleration or deceleration of the second object

Question 27

Length tension relationship

Answer 27

Resting length of a muscle and the tension the muscle can produce at this resting length

Question 28

Force couple

Answer 28

Muscle groups moving together to produce movement around a joint
