BELL, SIR CHARLES

born November 1774, Edinburgh, Scot. died April 28, 1842, North Hallow, Worcestershire, Eng. Scottish anatomist whose New Idea of Anatomy of the Brain (1811) has been called the "Magna Carta of neurology." A graduate of the University of Edinburgh, Bell went to London (1804), where he held surgical and teaching posts. In 1829 he received the first medal awarded by the Royal Society; he was knighted in 1831. He returned to Edinburgh in 1836 to accept the chair of surgery at the university. Bell's later research on the anatomy of the brain resulted in an expanded version of his 1811 volume, entitled The Nervous System of the Human Body (1830). In these books Bell distinguished between sensory nerves that conduct impulses to the central nervous system and motor nerves that convey impulses from the brain or from other nerve centres to a peripheral organ of response. He announced that the anterior roots of the spinal nerves are motor in function, while the posterior roots are sensory-an observation that was confirmed and more fully elaborated 11 years later by Franois Magendie.
