Which neurons carry incoming information from sense receptors to the central nervous system?

• A. Motor Neurons
• B. Interneurons
• C. Autonomic Neurons
• D. Sensory Neurons

Answer: (D)

Signals from sense receptors travel toward the brain through sensory neurons, which are also called afferent neurons. These cells detect stimuli such as light, sound, touch, and chemical changes, and convert that input into electrical impulses. The impulse then moves from the receptor toward the central nervous system, where it can be processed for perception or reflexive actions.

Motor neurons carry commands from the CNS to muscles to produce movement. Interneurons reside inside the CNS and connect other neurons to integrate information. Autonomic neurons regulate involuntary functions like heart rate and digestion. Since the task is to convey incoming information from sense organs to the brain, the sensory neurons are the best fit.
