The nervous system

  1. 1. THE NERVOUS SYSTEM1.- FUNCTIONS OF THE NERVOUS SYSTEM2.- THE BRAIN3.- THE SPINAL CORD4.- THE NERVES ENDINGS
  2. 2. Functions of the nervous system1.- It let us perceive what happens around us.2.- It let us form responses, like mouvements.3.- It co-ordinates all the organs and systems in the human body.4.- The brain, the spinal cord and the nerves form the nervous system
  3. 3. THE BRAINThe brain is in the head.The bones of skull protect it.Several organs form the brain:1.- the cerebrum,2.- the cerebellum3.- and the brain stem
  4. 4. 1.- The cerebrumIt is the biggest organ.It controls all voluntary actions (speaking too!!)It also stores data and experiences.It is related to feelings.
  5. 5. 2.- The cerebellumIt is located below the cerebrum.It co-ordinates movements.It controls balance.
  6. 6. 3.- The Brain StemIt communicates the brain with the spinalcord.It controls many organs in the human body (the heartbeats and the movements when we breathe)
  7. 7. THE SPINAL CORD It is in the back. It goes from the top to the bottom. It is protected by the vertebrae of the spinal cord. It is shaped like a cilinder. It is attached to the brain stem. Many nerves leave the spinal cord. They go to the organs and extremities. It controls involuntary movements (reflexes)
  8. 8. NERVESThey are shaped like long fibres.They communicate the brain and the spinal cordwith the rest of the human body.1.- Sensitive nerves: carry information from theorgans to the cerebrum and the spinal cord(auditory nerve)2.- Motor nerves: carry information from the brainand the spinal cord to the organsThey co-ordinate the function of the whole body
  9. 9. In your opinion, what Homer’s brain can co-ordinate?
