Vein because they have valves to prevent back flow of blood.
It is a vestigial Structure.
Explanation:
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
Answer:
