Substance P is best known for its role in what physiological process?

Substance P is a neuropeptide that acts as a key mediator in pain pathways. It is released from sensory neurons in response to tissue injury and binds to NK1 receptors in the dorsal horn of the spinal cord, enhancing the transmission of pain signals from the periphery to the brain. This makes it central to the perception and amplification of pain, including inflammatory amplification. While breathing, arousal, and sleep involve other brain regions and neurotransmitters, Substance P’s primary and most well-known role is in transmitting pain messages.
