Structures and Functions of the Brain 

  • The skull provides a hard, protective case
  • The brain weighs about 1.3 kg (just under 3 pounds)
  • A jelly like consistency held together by a number of layers of membrane (like a thick plastic bag) and surrounded by fluid (Cerebrospinal Fluid) to ‘cushion’ it inside the skull.
  • The brain is about 2% of body weight but uses 20% of oxygen in the blood.
  • Interruption for 2/3 minutes can cause brain cell death
  • Unlike skin or bone, brain cells do not re-grow

Lobe Functions

  • The brain is divided into 6 main areas called Lobes
  • Each Lobe is responsible for a main area of our functioning
