A neuron that carries impulses from a sense organ toward the central nervous system is classified functionally as which type?
AMotor neuron
BAssociation neuron
CSensory neuron
DBipolar neuron
Answer & Solution
Correct answer: C. Sensory neuron
1. The direction is from the sense organ toward the CNS.
2. Motor (efferent) neurons run the other way, from CNS to effector, ruling out option A.
3. Association neurons connect sensory and motor neurons, and bipolar is a structural class, ruling out options B and D.
4. The neuron carrying impulses to the CNS is the sensory (afferent) neuron, option C.
