During a spinal reflex arc, such as the rapid withdrawal of a hand from a hot surface, distinct classes of neurones coordinate the pathway of electrical impulses. The diagram below shows four types of neurones found in the human nervous system, labelled W, X, Y, and Z.
Which of the following correctly identifies the sensory neurone that transmits impulses from the receptor to the central nervous system, along with the correct anatomical location of its cell body?
Neurone W; cell body located within the dorsal root ganglion.
Neurone X; cell body located within the dorsal root ganglion.
Neurone X; cell body located within the grey matter of the spinal cord.
Neurone Y; cell body located within the ventral root of the spinal nerve.
