Biological Function of the Dorsal Horn

Nervous System

 Nerve Impulses from Sensory Nerves are conducted to their Presynaptic Terminals (on Axons) located in the Dorsal Horn of the Spinal Cord.

 

These Substances Influence the Dorsal Horn

Neurotransmitters

 Norepinephrine (NE) travels via a descending pathway that originates in the Locus Coeruleus of the Medulla of the Brain and terminates in the Dorsal Horn of the Spinal Cord to inhibit the release of Substance P (the Neuropeptide that initiates Nerve Impulses relating to Pain).
