- 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 .
The brain has three such major regions:-
- Fore brain
- Mid brain
- Hind brain.
- 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.
- 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
- 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.
