12)

receptor cell bodies are found in the dorsal ganglia which is F

relay cell bodies are found in the grey matter which is G

effector neuron bodies are found in the grey matter which is G

so the answer is D

13)

J is the dorsal root of the spinal nerve and contains the axons of the sensitive cells

H is the anterior root of the spinal nerve and contains the axons of the motor cells

therefore the answer is C

14)

F is the dorsal ganglion

I is the spinal nerve

hence, the answer is B

15)

first they come through the spinal nerve which is (I), then they go through the dorsal root, which is (J) then the impulses go through the grey matter(G) , they go through the anterior root(H) and finally through I

the answer is A
