Cell bodies of neurons bringing afferent information into the spinal cord are located in

Options

A. dorsal root ganglia
B. ventral root ganglia
C. grey matter of the spinal cord
D. white matter of the spinal cord

Explanation

To solve the question regarding the location of the cell bodies of neurons that bring afferent information into the spinal cord, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Spinal Cord:**
- The spinal cord is a vital part of the central nervous system and is segmented. Each segment of the spinal cord has spinal nerves that emerge from it.

2. **Identify the Components of Spinal Nerves:**
- Each spinal nerve is formed by two roots: the dorsal (posterior) root and the ventral (anterior) root. The dorsal root is responsible for carrying sensory information into the spinal cord.

3. **Focus on the Dorsal Root:**
- The dorsal root contains sensory axons that carry afferent (incoming) information from the body to the spinal cord. This is crucial for understanding where the cell bodies of these neurons are located.

4. **Locate the Cell Bodies:**
- The cell bodies of the sensory neurons that make up the dorsal root are not located within the spinal cord itself but are found in a cluster outside the spinal cord. This cluster is known as the dorsal root ganglion.

5. **Conclusion:**
- Therefore, the cell bodies of neurons bringing afferent information into the spinal cord are located in the dorsal root ganglion.

### Final Answer:
The cell bodies of neurons bringing afferent information into the spinal cord are located in the **dorsal root ganglion**.
