Sensory neurons carry signals to the brain. In which direction do these signals primarily travel?

• A. To the brain
• B. From the brain
• C. Within the brain
• D. To the spinal cord

Answer: (A)

Sensory information travels toward the brain. Sensory neurons are afferent, meaning they carry signals from receptors in the skin, organs, and other tissues toward the central nervous system. The typical path is from the periphery into the spinal cord and then upward to higher brain regions for processing and perception. The spinal cord acts as the initial relay and processing center, but the ultimate destination for conscious sensation is the brain. Motor neurons, in contrast, carry commands from the brain to muscles, heading in the opposite direction.
