PNSn
PNSn is a term used in some neuroscience texts and models to denote neurons associated with the peripheral nervous system. Because the literature does not always standardize the abbreviation, PNSn can refer broadly to neurons that reside outside the brain and spinal cord and participate in sensory, motor, or autonomic pathways, in contrast to CNSn, the central nervous system neurons.
Classification and examples: PNSn encompass sensory neurons (including pseudounipolar neurons in dorsal root ganglia), autonomic neurons
Development and biology: PNSn largely derives from neural crest cells in vertebrates; they migrate to peripheral
Function and clinical relevance: They mediate touch, pain, temperature, proprioception, and motor control, and are implicated
Terminology notes: The term PNSn is not universal; some authors use it to describe subpopulations within peripheral
