In a dorsal root ganglion, which cells surround and support the cell bodies of neurons?

• A. Schwann cells
• B. Satellite cells
• C. Neurons
• D. Fibroblasts

Answer: (B)

In the dorsal root ganglion, neuron cell bodies are enveloped by specialized glial cells that form a protective sheath around each soma. These satellite glial cells provide metabolic support, help regulate the extracellular environment, and stabilize the microenvironment around the neurons. Schwann cells are responsible for myelinating axons in the peripheral nervous system, not wrapping around neuronal somas. Fibroblasts are connective tissue cells that produce extracellular matrix, not the immediate neuronal support around cell bodies. Neurons themselves are the cells inside the ganglion, not the surrounding support cells. So the cells that surround and support the neuron cell bodies in the dorsal root ganglion are satellite cells.
