In an introductory college physics class, we studied different
topics throughout the course of a semester such as electric
charge, electric currents, potential difference and circuits. We
can apply the same principles that we learned about the flow of
electric charge in the human nervous system. The
nervous system is an intricate, highly organized network of
billions of neurons and neuroglia. The nervous system consists of
the brain, spinal cord, spinal nerves and their branches, cranial
nerves and their branches, ganglia, enteric
plexuses and sensory receptors. The nervous
system serves as the body control center and communications
electrical chemical wiring network. As a homeostatic regulatory
and coordinating system, the nervous system receives and
integrates information and sends electrochemical information
though nerves to effector cells such as a muscle cell or a gland
cell.
