Human Brain :-
Weighing at just 2% of the total body weight, the human brain is probably most complex structure.
It is the centre of control of all the body functions and senses.
The average weight of human brain is around 1.5 kg and it contains about 86 billion nerve cells.
The Human Brain along with the spinal cord, make up the Central Nervous System in humans. It is the command centre for the nervous system. The brain controls your smallest to largest all functions.
Location of Human Brain :
Brain is enclosed within the skull, which provides frontal, lateral and dorsal protection.
Parts of Human Brain :
The human brain is made up of different parts and compartments .
- Fore brain
- Mid brain
- Hind brain
••• Forebrain •••
It is the main thinking part of the brain and controls the voluntary actions. The forebrain processes sensory information that is collected from the various sense organs.
It is because of the forebrain, humans are placed at the highest level in the animal chain.
The forebrain consists of the Cerebrum , Thalamus and Hypothalamus .
••• Midbrain •••
The midbrain connects the forebrain and the hindbrain. It acts as a bridge and transmits signals from hindbrain and forebrain. It is associated with motor control, vision, hearing, temperature regulation, alertness.
••• Hindbrain •••
It is the control centre for visceral function. This part of the brain plays a role in controlling the heart rate, breathing, blood pressure, sleep and waking up functions etc. The hindbrain has three parts - medulla oblongata, pons and cerebellum.
