dorsal root

The sensory root of a spinal nerve is also referred to as the dorsal root. This root contains sensory nerve fibers that carry signals from the peripheral sensory receptors (such as in the skin, muscle, and joints) to the spinal cord. These signals are transmitted through the dorsal root ganglion, which contains cell bodies of sensory neurons. Upon reaching the spinal cord, these signals synapse with interneurons that integrate and relay the sensory information to other parts of the nervous system, including the brain. The dorsal root is distinct from the ventral root, which contains motor nerve fibers that carry signals from the spinal cord to the muscles and glands.
