This nociceptive fiber (situated in the periphery) is a primary get neuron. The cells while in the dorsal horn are divided into physiologically distinctive levels called laminae. Diverse fiber sorts type synapses in numerous levels, and use either glutamate or compound P as being the neurotransmitter.
