Prize share: 1/2
Our bodily functions are governed by our nervous system, which consists of many nerve cells with extensions, or nerve fibers, that form a system of connections between the brain and spinal cord and the rest of the body. Signals in the nervous system are conveyed by weak electrical currents and by chemical substances. During the 1920s Herbert Gasser and Joseph Erlanger studied the properties and distribution of nerve fibers. They divided nerve fibers into two different types with different thicknesses and showed that the thicker fibers convey nerve impulses faster.
