Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord is divided into regions that include gray matter and white matter. Gray matter is organized into horns (dorsal, ventral, and lateral), while white matter contains tracts for transmitting signals.

Identify the function of the dorsal horn: The dorsal horn is part of the gray matter and is responsible for processing sensory information, such as touch, pain, and temperature, which is then transmitted to the brain.

Differentiate the roles of other structures: The central canal contains cerebrospinal fluid and is not involved in sensory transmission. The ventral horn is responsible for motor functions, and the anterior median fissure is a groove that separates the spinal cord into left and right halves but does not transmit sensory information.

Correlate sensory transmission with the dorsal horn: Sensory neurons enter the spinal cord through the dorsal root and synapse in the dorsal horn, where sensory signals are processed before being sent to the brain via ascending tracts in the white matter.

Conclude that the dorsal horn is the correct structure responsible for transmitting sensory information to the brain, based on its anatomical location and function.
