Verified step by step guidance

Understand the anatomy of the spinal cord: The spinal cord is divided into regions, including the central canal, ventral horn, anterior median fissure, and dorsal root ganglion. Each structure has a specific function and location.

Learn the role of sensory neurons: Sensory neurons are responsible for transmitting sensory information (e.g., touch, temperature, pain) from the body to the central nervous system. Their cell bodies are located in specialized structures.

Identify the dorsal root ganglion: The dorsal root ganglion is a cluster of sensory neuron cell bodies located outside the spinal cord, along the dorsal root of a spinal nerve. It is a key structure for sensory signal processing.

Differentiate the other structures: The central canal contains cerebrospinal fluid, the ventral horn contains motor neuron cell bodies, and the anterior median fissure is a groove that separates the left and right halves of the spinal cord. None of these structures house sensory neuron cell bodies.

Conclude that the dorsal root ganglion is the correct structure: Based on its function and location, the dorsal root ganglion is the site where sensory neuron cell bodies are found in a cross-section of the spinal cord.
