<prompt> The cell body of all sensory neurons is located within theDorsal gray hornDorsal root ganglionSpinal cordBrain  <response>: B: The cell bodies of the sensory neurons leading to the spinal cord are located in clusters, the dorsal root ganglia DRG, next to the spinal cord.A: Dorsal gray horn is a mass of gray matter found in every segment of the spinal cord and is responsible for the processing system of sensory signals that travel within the spinal cord,C: The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the foramen magnum at the base of the skull to the second lumbar vertebrae.D: Brain serves as a command center for the human nervous system. It receives input from the sensory organs and sends output to the muscles.
