  A) Cerebal Cortex

  B) Cerebellum

  C) Pituitary gland

  D) Hypothalamus

  E) Medulla

  
• Cerebal Cortex

  • Responsible for: consciousness, intelligence , memory, language and senses.
  • It is split into two hemispheres.
  • The left hemishpere controls the right hand side muscles. while the right hemishpere controls the left hand side muscles.
  • It is the outer part of the brain.
• Cerebellum

  • Responsible for: balance and coordination
  • It is found at the back/bottom of the brain
• Hypothalamus

  • Responsible for: regulating the body's temperature and sending signals to pituitary gland.
  • It is found in the centre of the brain, before the pituitary gland.
• Medulla

  • Responsible for: controlling unconscious activities (e.g. breathing and heart rate).
  • It is found within the brain stem.
• How scientists study the brain:

  1. Study people with brain damage.
  2. Electrically stimulate different parts of the brain.
  3. Scanning the brain, with CT, PET and MRI scans.
• Why treating the brain is so difficult:

  • The brain is complex and isn't fully understood. So it can't be treated with drugs.
  • The brain is in the skull and brain tissue is very fragile. So it's physcially i,possible to fix anything.
  • Many things can go wrong such as: tumours, trauma, infections and mental health problems.
