Question

a neuron that conducts pain sensations to the central nervous system would be classified as a(n):
a motor neuron
b interneuron
c efferent neuron
d association neuron
e sensory or afferent neuron

Explanation:

• Motor neurons (A) send signals from the central nervous system to muscles or glands.
• Interneurons (B) and association neurons (D) are mainly within the central nervous system, facilitating communication between neurons.
• Efferent neurons (C) are the same as motor neurons in the context of sending signals away from the central nervous system.
• Sensory or afferent neurons (E) carry sensory information (such as pain sensations) to the central nervous system.

Answer:

E. sensory or afferent neuron
