  2. Mechanoreceptors • Stimulated by mechanical forces such as pressure • Include receptors for touch, hearing,

  3. Chemoreceptors • Detect chemicals or chemical changes • The sense of smell and taste rely on chemoreceptors

  4. Electromagnetic Receptors • React to heat and light energy • The photoreceptors of the eyes that detect light are examples • The thermal receptors found in some reptiles

  5. Vision

  6. Eye • Sclera: white of the eye • Cornea: transparent part of the eye that begins the focusing of light • Iris: the colored portion of the eye • Lens: a transparent structure which completes the focusing of light

  7. Rods • Shaped like rods • Responsible for the black and white vision when light is dim

  8. Cones • Shaped like a cone • Responsible for high visual sharpness • Responsible for color vision • Color blindness is caused by an inherited lack of one or more cones

  9. True or False: • Women tend to be more color-blind than men (False) • Rods are responsible for the black and white vision when light is dim (True) • The cornea is the colored portion of the eye (False) • The Lens is the transparent structure which completes the focusing of light (True) • Color-blindness is caused by having too many cones (False)

  10. Multiple Choice • Electromagnetic receptors: • React to heat and light energy • Are the photoreceptors of the eyes that detect light are examples • Are the thermal receptors found in some reptiles • All of the Above (Answer=D)
