Document Summary

Neuroscientists think of the nervous system as a system of twos . As you can see in this outline of the elements of the nervous system, things come in twos: spinal cord communicates with all sensory organs and muscles, except those of. The nervous system: central nervous system (cns, brain, spinal cord the head, peripheral nervous system (pns, skeletal nervous system, sensory or afferent, motor or efferent, autonomic nervous system, sympathetic, parasympathetic. Each contains both sensory and motor nerves: skeletal portion controls various muscles, relaying motor commands from the brain, the autonomic nervous system (ans) controls involuntary muscles (e. g. , heart and diaphragm) and many internal organs (e. g. , the viscera). Glia: cns composed of two broad classes of cells: neurons and glia, different kinds of glia or glial cells; they serve supportive and protective functions. Neurons: transmitting information: neurons are specialized cells capable of transmitting information.
