The nervous system sends messages from nerve endings to the brain and from the brain to cells, tissues, and organs. Cells of the nervous system sometimes secrete chemical messengers instead of neurotransmitters. These specialized nervous system cells are called neurosecretory cells, and they produce neurosecretions. Every nerve cells are long, thin cylinders along which electrical disturbances (nerve impulses) travel. the cell membrane of a typical nerve cell consists of an inner and an outer wall separated by a distance of 0.10 μm and the electric field within the cell membrane is 7.0×105n/c.
