The brain controls all of our actions and is the controlling centre of the body. The brain and the spinal cord are made up of a very delicate and soft material, which occupies the whole of the skull and the long central core of the backbone.
Special nerves are linked to this sensitive material which transmit to brain all the sensations received from various sense organs.
These nerves then pass on at once, the orders, which the brain sends back to the organs, even to the remote areas of the body. It is due to the nervous system and the brain that we are able to appreciate and understand our senses.
Below Brain info from Wikipedia (Read More):-
The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. Some primitive animals such as jellyfish and starfish have a decentralized nervous system without a brain, while sponges lack any nervous system at all. In vertebrates, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell.
Brains can be extremely complex. The cerebral cortex of the human brain contains roughly 15-33 billion neurons depending on gender and age[1], linked with up to 10,000 synaptic connections each. Each cubic millimeter of cerebral cortex contains roughly one billion synapses.[2] These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body and target them to specific recipient cells.
