| photoreceptors | light-vision |
| chemoreceptors | chemicals-tatse and smell |
| pain receptors | injury-warning system |
| thermoreceptors | temp. change |
| mechanorecptors | move and pressure-viberation |
| proprioceptors | body position |
| all sense organs have common functional characteristics- | all are able to detect stimulus-heat a stimulus is converted into a nerve inpulse- transduction-thermal receptor a nerve impulse is percieved as a sensation in the CNS- hot, pain |
| free nerve endings | pain, temp., crude touch |
| tactile corpuscles | fine touch-vibraton |
| bulbous corpuscles | touch-pressure-strech |
| lamellar corpuscles | pressure-vibration |
| bulboid corpuscles | touch, light touch |
| golgi tendon receptors | tendons- prevent injury |
| muscle spindles | stretch, balance |
| special senses - struture of eye and function | sclera- white of eye- protection |
