Answer 12

Frontal/coronal plane

Question 13

An example of movement in this plane would be bending side to side

Answer 13

Frontal/coronal plane

Question 14

Name the plane:divides the body into right and left halves

Answer 14

sagittal plane

Question 15

An example of movement in this plane would be bending trunk forward and backward

Answer 15

sagittal plane

Question 16

Name the plane:divides the body into upper and lower sections/ like a view from above

Answer 16

horizontal or transverse plane

Question 17

An example of movement in this plane would be twisting at the waist

Answer 17

horizontal or transverse plane

Question 18

Movement occurs ______ to the plane

Answer 18

parallel

Question 19

The point around which movement occurs

Answer 19

pivot point

Question 20

Name the axis:runs horizontally from one side of our body to the other; perpendicular to sagittal plane

Answer 20

Frontal or “X” axis

Question 21

Name the axis:perpendicular to the ground

Answer 21

Vertical or “Y” axis

Question 22

Name the axis:passes horizontally through our body from the front to the back

Answer 22

Sagittal or “Z” axis

Question 23

Which movement does not occur in the sagittal plane around the frontal (x) axis?1. Flexion2. Extension3. Abduction4. Hyperextension5. Dorsiflexion/Plantarflexion

Answer 23

3. Abduction (occurs in the frontal plane around (Z) axis

Question 24

Which movement does not occur in the frontal plane around the sagittal (Z) axis?1. Internal rotation2. Abduction3. Adduction4. Lateral Flexion5. Radial/Ulnar deviation

Answer 24

1. Internal rotation (occurs in the transverse plane around (Y) axis)

Question 25

Which movement does not occur in the transverse plane around the (Y) axis?1. Supination2. Pronation3. Extension4. Internal rotation5. External rotation

Answer 25

3. Extension (occurs in sagittal plane around the (x) axis)

Question 26

Sequence of movements of flexion, extension, abduction, and adduction so the segment describes a cone

Answer 26

circumduction

Question 27

imaginary point representing the weight center of an object

Answer 27

center of gravity (COG)

Question 28

T/F: Any change from the anatomical position will change the location of the COG

Answer 28

trueWhen crouching down, COG is lowered; when raising hands, COG is raised…etc.

Question 29

T/F: Body segments do not have their own center of gravity

Answer 29

False: each segment of the body is acted upon by the force of gravity and has its own COG

Question 30

Which of these is a factor affecting stability?1. height of the COG above the base of support2. the size of the base of support3. the location of gravity line within the base of support4. the weight of the body5. All of the above6. None of the above

Answer 30

5. all of these are factors affecting stability

Question 31

T/F: There is a payoff between stability and mobility

Answer 31

True
