This program discusses the development, organization, and functions of the nervous system and the input organs that stimulate it. Beginning with an introductory overview of neural anatomy, the video outlines the organization of the central and peripheral nervous systems and the processes of sensation, transduction, and perception. In addition, the senses of vision, hearing, taste, smell, and equilibrium are analyzed, as well as sensitivities to temperature, pressure, and pain; bodily movement via the somatic neurons is illustrated; and the neural mechanics of sleep and wakefulness are considered. A viewable/printable instructor’s guide is available online. A Films for the Humanities & Sciences Production. A part of the series The Human Body: How It Works. (21 minutes)
