What 2 structures merge to create a spinal nerve?

A spinal nerve is formed by the merging of the dorsal (sensory) root and the ventral (motor) root. The dorsal root contains sensory neurons that transmit information from the body to the spinal cord, while the ventral root contains motor neurons that carry signals from the spinal cord to the muscles. Together, these roots combine to form a spinal nerve, which serves as a conduit for both sensory and motor information.
