Question 1

Sagittal plane

Answer 1

Vertical plane which divides the body into left and right halves.

Question 2

Frontal plane

Answer 2

Vertical plane which divides the body into front and back halves.

Question 3

Transverse plane

Answer 3

Horizontal plane dividing the body into upper and lower halves.

Question 4

Movements on transverse axis

Answer 4

Extension and flexion

Question 5

Sagittal axis

Answer 5

Adduction and abduction

Question 6

Longitudinal axis

Answer 6

Rotation

Question 7

Articulating

Answer 7

Refers to the bones that meet and move at a joint.

Question 8

Where does the transverse axis run

Answer 8

From side to side across body

Question 9

Where does the sagittal axis run

Answer 9

Front to back

Question 10

Where does longitudinal axis run

Answer 10

Top to bottom

Question 11

Fast Effective Pressure Denies Harry Some Time (memory tool)

Answer 11

Flexion, Extension, Plantar-flexion, Dorsi-flexion and hyper-extension occur in a sagittal plane about a transverse axis.

Question 12

Agonist

Answer 12

The muscle that contracts to create a movement.

Question 13

Antagonist

Answer 13

The muscle that relaxes to work in opposition to the agonist, allowing movement.

Question 14

Concentric contraction

Answer 14

When a muscle shortens under contraction.

Question 15

Eccentric contraction

Answer 15

When a muscle lengthens under contraction or performs negative work and acts like a brake

Question 16

Isometric contraction

Answer 16

When a muscle is under tension but there is no visible movement.
