Transcript of "Sensitivity and coordination by Alba and Lucía"

  1. 1. SCIENCEsensitivity & coordination BY Alba & Lucía
  2. 2. Stimulus & ResponsesSTIMULIA stimulus is anything you see, hear, smell OR taste.Stimuli can be external or internal.RECEPTORS·Internal receptors·External receptors
  3. 3. RESPONSESA response is the body’s answer to a stimulus.·Muscular responses·Glandular responses
  4. 4. SENSES (SIGHT)The eye is the organ of sight.It’s made up of the eyeball and protected by eyebrows, eyelids and eyelashesPROCESS·FIRST light passes through the cornea.·THEN light passes through the pupil·AFTER THAT light passes through the lens, which focuses the image on the retina·FINALLY the information in the retina travels to the brain through the optic nerve.
  5. 5. SENSES (SMELL)The nose is the organ of smell.The receptors of smell are in the pituitary, inside the nostrils.
  6. 6. SENSES (HEARING)The ear is the organ of hearing. It has three parts:·OUTER EAR: ear and ear canal·MIDDLE EAR: eardrum and small bones·OUTER EAR: cochlea and auditory nervePROCESSFIRST the outer ear receives soundsTHEN the middle ear changes sounds into vibrations.FINALLY the inner ear changes vibrations into nerve impulses that go to the brain
  7. 7. SENSES (TOUCH & TASTE)-The skin is the organ of touch. It has three layers.-The tongue is the organ of taste. The receptors of taste are in the taste buds. There are taste buds all around the tongue.
  8. 8. NERVOUS SYSTEMThe nervous system is made up of nerve centres and nerves.Nerve centres:-Interpret information-Develop responses
  9. 9. NERVOUS SYSTEMCENTRAL NERVOUS SYSTEM-BRAIN: is inside the skull. It’s made up of cerebellum, cerebrum and brain stem.-SPINAL CORD: It’s made up of many neurons and protected by vertebrae.PERIPHERAL NERVOUS SYSTEM-SENSORY NERVES-MOTOR NERVES
  10. 10. NEURONSNeurons are specialised cells.They are made up of a cell body, dendrites and axons.
  11. 11. MOVEMENTSVOLUNTARYIn this case, is the brain who produces a responseINVOLUNTARYIn this case, is the spinal cord who produces a response
  12. 12. SKELETAL & MUSCULAR SYSTEM
