Group of answer choices
1. sensory receptor --> afferent neuron --> dorsal root ofspinal nerve --> dorsal horn of spinal cord --> descendingtract --> brainstem --> cerebrum
2. sensory receptor --> efferent neuron --> ventral rootof spinal nerve --> ventral horn of spinal cord -->descending tract --> brainstem --> cerebrum
3. sensory receptor --> efferent neuron --> ventral rootof spinal nerve --> dorsal horn of spinal cord --> ascendingtract --> brainstem --> cerebrum
4. sensory receptor --> afferent neuron --> dorsal root ofspinal nerve --> dorsal horn of spinal cord --> ascendingtract --> brainstem --> cerebrum
sensory receptor --> afferent neuron --> dorsal root ofspinal nerve --> lateral horn of spinal cord --> ascendingtract --> brainstem --> cerebrum
