Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord is divided into regions that include the gray matter (ventral horn, dorsal horn) and white matter, as well as associated structures like the dorsal root ganglion and central canal.

Recall the function of sensory neurons: Sensory neurons are responsible for transmitting sensory information (e.g., touch, pain, temperature) from the peripheral nervous system to the central nervous system.

Identify the dorsal root ganglion: The dorsal root ganglion is a cluster of nerve cell bodies located outside the spinal cord, specifically along the dorsal root of a spinal nerve. It contains the cell bodies of sensory neurons.

Differentiate the other structures: The ventral horn contains motor neuron cell bodies, the anterior median fissure is a groove on the spinal cord's surface, and the central canal is a small channel filled with cerebrospinal fluid. None of these structures house sensory neuron cell bodies.

Conclude that the dorsal root ganglion is the correct structure containing the cell bodies of sensory neurons, based on its anatomical location and function.
