PNS
Body's neural branches
PNS is an abbreviation with two common meanings.
In anatomy, it stands for peripheral nervous system—the network of nerves outside the brain and spinal cord.
In texting and casual online communication, PNS is shorthand for penis, used to avoid filters or for comedic effect: sent him a pic of my PNS.
