Simple Lab. Instructions will be attached.
Introduction: The human nervous system is composed of the brain and spinal cord (Central Nervous System, CNS) and the nerves which branch out from the CNS, the Peripheral Nervous System (PNS). Sensory neurons of the PNS carry information to the CNS. Signals from the brain are carried to motor neurons (PNS), which carry out responses by muscles. In this lab, we will be mapping out the density of sensory neurons on the skin and mapping out your visual blind spot as well as acoustic testing.
