HUMAN BRAIN - Teachoo.jpg

  • Brain is the main coordination center of the human body . The brain coordinates the input and output signals through a complex design. It is the widest and uppermost part of the human body .

HUMAN BRAIN STRUCTURE - Teachoo.jpg

The brain has three such major regions:-

  1. Fore brain
  2. Mid brain
  3. Hind brain.

BRAIN MAJOR REGIONS - Teachoo.jpg

Forebrain

  • It is the part associated with thinking .
  • The various sensory receptors discussed above receive the inputs.
  • There are various regions in the forebrain that perform the same.
  • The stimuli sensed and information already available in the brain are put together and interpreted.
  • Cerebrum 
    • Large outer part of the brain. 
    • Controls reading, speaking, hearing, thinking, vision, learning, emotions, and other senses.

Now these stimuli are associated with the sense organs in our body.

  • But, how do you feel hungry and once you eat enough food, how do you feel full?
    • This is associated with another center in the forebrain known as Hypothalamus.
    • The Hypothalamus controls human appetite.
  • Another important part of the forebrain is the pituitary gland .
    • It is referred to as the “master gland”.
    • It monitors and regulates many bodily functions through the hormones that it produces.
  •  

Midbrain and Hindbrain

  • The actions that happen without thinking are called involuntary actions.
  • Blood pressure, salivation and vomiting are controlled by the medulla in the hind-brain.
  • The precision of voluntary actions is the responsibility of the cerebellum in the hindbrain.
  • Cerebellum is also responsible for balance and posture of the body.

 

  • The brain continues with the spinal cord by the Brainstem or Medulla Oblongata.
    • Connects cerebrum with the spinal cord
    • Includes the midbrain, pons and medulla
    • Controls breathing, eye movements, blood pressure, heartbeat, swallowing etc.
