Answer: Sensory neurons/cells located in the dorsal root ganglion.
Explanation: Sensory information from the skin, skeletal muscle and joints are relayed to the spinal cord and brain by sensory neurons/cells in dorsal roots, the dorsal roots enter the spinal cord in small bundles called dorsal rootlets. The cell bodies for these sensory neurons are packed closely together to form a structure called the dorsal root ganglion, which is located alongside the spinal cord.
