Sensory systems are designed to detect signals from the environment, such as sound waves, odors, and tastes. Sensory organs like [[eyes]], [[ears]], [[nose]], and the [[tongue]] have specialized [[cells]] equipped for sensing specific types of stimulus. For example, you can hear the phone ring because sound waves vibrate hairlike projections (called stereocilia) that extend from cells in your inner [[ear]]. The message is then communicated through the [[nervous system]]. Similarly, to see and smell the world around you and taste its variety of flavors, your body must convey molecular signals from the environment into your sensory cells.<ref name=nigms>[http://publications.nigms.nih.gov/insidethecell/chapter3.html Inside the Cell.
