What types of neurons are responsible for carrying stimuli in brain and spinal cord?

1. A. Interneurons
2. B. Motor neurons
3. C. Sensory neurons
4. D. Undifferentiated neurons

Answer: C. Sensory neurons

Sensory neurons:

• Carry information about the environment (touch, taste, smell, sight, hearing) from sensory receptors to the brain and spinal cord.
• Have long axons that extend from the periphery to the central nervous system.
• Examples include:
  • Olfactory neurons (smell)
  • Retinal ganglion cells (vision)
  • Spiral ganglion cells (hearing)
  • Dorsal root ganglion cells (touch, pain)
