He was the father of poet Gábor Karinthy and writer Ferenc.

A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system.A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs.
