Which term is specifically associated with a capsule around a dorsal root ganglion?

• A. Perineurium
• B. Capsule of dorsal root ganglion
• C. Endoneurium
• D. Epineurium

Answer: (B)

The capsule around a dorsal root ganglion is a distinct protective covering named the capsule of dorsal root ganglion. Dorsal root ganglia are clusters of sensory neuron cell bodies outside the CNS, and this capsule directly surrounds the ganglion itself, separating it from the surrounding connective tissue and nerve fibers. In contrast, the perineurium encases individual nerve fascicles within a nerve, the endoneurium wraps around each axon, and the epineurium is the outermost sheath surrounding the entire nerve. Since the question asks for the term specifically associated with the capsule around the dorsal root ganglion, the correct term is the capsule of dorsal root ganglion.
