Charles Bell was a Scottish surgeon-anatomist who early on published "Essays on the Anatomy of Expression in Painting" for instructing artists and this was based on his anatomic knowledge.

He established that the nerves of the special senses could be traced from specific areas of the brain to their end organs. He clearly demonstrated that spinal nerves carry both sensory and motor functions and that sensory fibers traverse the posterior roots whereas the motor fibers run through the anterior (Bellís Law). He also demonstrated that the cranial nerve V was sensory to the face and motor to mastication whereas cranial nerve VII controlled muscles of expression. The eponyms of the respiratory nerve of Bell and Bellís Palsy perpetuate his name.
