Which region is associated with sensory processing?

• A. Anterior horns
• B. Ventral root
• C. Lateral horns
• D. Posterior horns

Answer: (D)

Sensory processing happens in the dorsal (posterior) region of the spinal cord’s gray matter. That area receives incoming sensory information via the dorsal roots and houses interneurons that modulate and relay those signals toward higher brain centers or into reflex circuits. Because this region is dedicated to receiving and processing sensory afferent input, it’s the part of the spinal cord most closely tied to sensing the body's internal and external conditions. In contrast, the ventral (anterior) horns contain motor neurons that send commands to muscles, and the lateral horns (in certain segments) contain autonomic preganglionic neurons, which are not primarily about sensory processing.
