This 29-minute video helps students visualize the structure of the spinal cord and the origins of the spinal nerves from the cord using the "real thing"—a dissected cadaver. Illustrations and figures assist students in learning the organization of the spinal nerves into complicated plexuses and also in learning the function of the nerves. Major nerves arising from these plexuses are traced on the cadaver as they course through the upper and lower extremities.
