F-Grey matter
(iii)Receptor cells (skin cells)

D-(Association neuron) receives impulses from C and passes them to the motor neuron.
G-(Motor nerve) carries response impulses towards the effector organs.
The technical term given to the pathway represented by C,D,G is the reflex arc.

In the brain,the arrangement is exactly opposite.The grey matter lies outside and the white matter lies on the inner side.
