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. Sensory neurons are responsible for transmitting sensory information from the body 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 in the dorsal root of a spinal nerve. It contains the cell bodies of sensory neurons.

Differentiate the other structures: The ventral horn is part of the gray matter in the spinal cord and contains motor neuron cell bodies. The central canal is a small channel in the spinal cord that contains cerebrospinal fluid. The anterior median fissure is a groove on the anterior side of the spinal cord and does not contain neuron cell bodies.

Relate the function of sensory neurons to the dorsal root ganglion: Sensory neurons transmit signals from peripheral sensory receptors to the central nervous system. Their cell bodies are housed in the dorsal root ganglion, which is located near the spinal cord.

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