  1. 1. NERVES AND SENSES BY:ANA GARCIA CALDERÓN
  2. 2. VOLUNTARY MOVEMENTS: Our sense organ detect information about the enviroment and send it to the brain. Then the brain interprets the information and react. Motor nerves transmit nerves impulses to the muscles.
  3. 3. INVOLUNTARY MOVEMENTS: Our sense organ detec information about the enviroment and send it to the spnal cord. It interpretes information and reacts quickly. Motor nerves transmit the nerve impulses from the spinal cord to muscles.
  4. 4. SHIGHT Close and open the eye Transparent layer that Protect the pupil Small hole that lets light into the eye It focuses light on the retina Coloured part Has got optic cells that detect lihgt and colours, send information to the brain.
  5. 5. HOW DO THE EYE WORK Light goes to the eye through pupil and lens. Lens project an upside down image onto the retina. The optic cells detect lights and colours. They send nerve impulses to the optic nerve . The optic nerve transmit nerves impulses to the brain. The brain interpretes information.
  6. 6. SMELL
  7. 7. TASTE
  8. 8. HEARING  Outer ear: eardrum and ear canal.  Middle ear: hammer, anvil and stirrup.(ossicles)  Inner ear: semicircular canal and cochlea. ossicles Semicircular canals auditory nerve cochlea
  9. 9. HOW DO THE EAR WORK The sound waves go into the ear canal and hit the eardrum Eardrum vibrate When eardrum vibrates transmit this vibrations to the cochlea. The cochlea produces nerve impulses. Auditory nerve transmit these impulses to the brain. Finally the brain interprets the information.
  10. 10. TOUCH There are nerve endings in the dermis. They detect information. Then sensory nerves transmit nerve impulses to the brain. The brain interprets information. Your skin keeps bacteria and microbes out of your body and it uses sunlight to have vitamin D and to control your body´s temperature.
