Answer 7

wrist joint similar to ball and socket

Question 8

Circumduction

Answer 8

limb goes in a circular motion e.g bowling

Question 9

Horizontal flextion/ extension

Answer 9

limb moves forwards/ backwards from the body

Question 10

Frontal plane of movement

Answer 10

front and back (abduction + adduction)

Question 11

Sagittal plane of movement

Answer 11

Divides body into left and right (flexion + extension)

Question 12

Transverse plane of movement

Answer 12

Divides body into upper and lower (horizontal flexion + extension)

What determines amounts of SO/ FG?

Answer 27

genetics- although FOG can be adopted

Question 28

How do muscles contract?

Answer 28

being stimulated by an electrical pulse sent by the CNS

Question 29

Motor neuron

Answer 29

impulse to muscle fibres action potential conducts it done in an all or none law
