This nociceptive fiber (situated in the periphery) is a primary order neuron. The cells in the dorsal horn are divided into physiologically distinctive levels called laminae. Diverse fiber types variety synapses in various levels, and use possibly glutamate or substance P because the neurotransmitter. Aδ fibers sort synapses in laminae I and V, C fibers join with neurons in lamina II, Aβ fibers hook up with lamina I, III, & V.

2 It's also phosphorylated by G-protein-coupled receptor kinases and binds arrestins, especially when activated by higher-efficacy agonists. There's been in depth discussion concerning the likely therapeutic benefits of biased agonists that may activate only Some pathways. A deeper knowledge of the conversation amongst the µOR and its ligands could therefore bring on the event of latest drugs with less Unintended effects.
