B. 2nd Order Neurons

C. 3rd Order Neurons

D. Upper Motor Neurons

E. Lower Motor Neurons

a) First-order Neurons- It is the pseudounipolar neurons with the dorsal root ganglion.

b) Second-Order Neurons- It sends afferent to the thalamus

C) Third-order Neurons- It sends afferents to the primary sensory cortex.
