: A set of 12 pairs that emerge directly from the brain or brain stem, primarily controlling functions in the head and neck, such as sight (Optic nerve) and smell (Olfactory nerve). The Architecture of Sensation : Carrying command signals

The human nervous system is an intricate network of "biological cables" known as nerves, which act as the body's primary communication superhighway. From the rhythmic beat of your heart to the sharp sensation of a bee sting, every experience and movement is mediated by these fiber-like structures that transmit electrical and chemical signals between the brain and the rest of the body.
