The Musculoskeletal System

Question 1

What is the sagittal plane

Answer 1

Divides the body into right and left halves

Question 2

What is the frontal plane

Answer 2

Divides the body into front and back halves

Question 3

What is the transverse plane

Answer 3

Divides the body into upper and lower halves

Question 4

What is the transverse axis

Answer 4

Transverse axis that runs from side to side across the body

Question 5

What is the sagittal axis

Answer 5

Sagittal axis which runs from front to back

Question 6

What is the longitudinal axis

Answer 6

Longitudinal axis that runs from top to bottom

Question 7

What is flexion

Answer 7

Decreases the angle between the bones of a joint

Question 8

What is extension

Answer 8

Increasing the angle between the bones of a joint

Question 9

What is plantar flexion

Answer 9

Pointing the toes / pushing up onto your toes

Question 10

What is dorsi flexion

Answer 10

Pulling the toes up to the shin

Question 11

What is hyper extension

Answer 11

Increasing the angle beyond 180 degrees of a point

Question 12

What is abduction

Answer 12

Movement away from the midline of the body

Question 13

What is adduction

Answer 13

Movement towards the midline of the body

Question 14

What is an agonist

Answer 14

The muscle which is responsible for the movement that is occurring

Question 15

What is the antagonist

Answer 15

The muscle which works in opposite to the agonist (to help produce co-ordinated movement)

Question 16

What are the two types of isotonic contraction

Answer 16

Concentric contraction
Eccentric contraction

Question 17

What is concentric contraction

Answer 17

When a muscle shortens under tension

Question 18

What is eccentric contraction

Answer 18

This is when the muscle lengthens under tension. When a muscle contracts eccentrically its acting as a break to help control the movement of the body

Question 19

What is Isometric contraction

Answer 19

When a muscle is under tension but there is no visible movement such as holding the crucifix position as a gymnast

Question 20

What type of movement occurs in the sagital plane about a transverse axis ?

Answer 20

Flexion, extension, plantar-flexion, dorsi-flexion and hyper extension

Question 21

What movement occurs on the frontal Plane about a sagittal axis ?

Answer 21

Abduction and adduction

Question 22

What movement occurs on the transverse plane about the longitudinal axis ?

Answer 22

Horizontal abduction and horizontal adduction

Question 23

What is horizontal adduction ?

Answer 23

Horizontal adduction is movement of the arm forward across the body at 90 degrees to shoulder abduction

Question 24

What is horizontal abduction ?

Answer 24

Horizontal abduction is movement of the arm backwards across the body to shoulder abduction
