Which type of neuron carries signals from sensory receptors to the CNS?

• A. Interneuron
• B. Relay neurone
• C. Motor neurone
• D. Sensory neurone

Answer: (D)

Signals from a stimulus are detected by sensory receptors and converted into nerve impulses that travel along a sensory neurone toward the CNS. This neurone is specialized to carry information from the periphery to the brain or spinal cord, making it the sensory neurone. Inside the CNS, these impulses may be relayed by interneurons (relay neurones) to other neurons, such as motor neurones that carry impulses from the CNS to effectors like muscles. So the type of neuron that carries signals from sensory receptors to the CNS is the sensory neurone.
