These receptors reside on peripheral neurons whose fibers enter the spinal cord, and then synapse onto neurons in the spinal cord. The neurons containing nociceptors are called first-order neurons.
First order neurons transmit the pain signal to several other neurons in the spinal cord. One is an ...
