Brain - Urvish Singh

The brain is the most complex and mysterious organ, and still, scientists are researching how it works. The brain is two per cent of our whole body weight, but it uses approximately 20% energy of our body. As our body is made up of cells, the brain is also made up of neurons called brain cells, and approximately three billion neurons collectively form our brain. If you talk about the structure of a neuron, it has different parts like dendrites, axon, and terminal bottom, where dendrite is a hair-like structure, the axon is the middle part of the neuron, and the terminal bottom is the tail. Whenever we see something, listen to something or feel something, our sense organs send electrical signals to our brains through these neurons only, and the brain interprets this information. 

The brain is divided into two parts-left and right. Whenever we do something with our left side, our right brain works, and whenever we do any work with our right side, our left brain is working again. The brain is divided into three parts which are the forebrain, midbrain and hindbrain. The brain constitutes the cerebrum which is the biggest part of our brain and approaches 70% of our brain. This part and decides our thinking power and behaviour. It also controls the contraction and relaxation of our muscles. Another part is telecasters and the hypothalamus, which gives us information about temperature and the hypothalamus, which controls our feelings.

It consists of two parts which are Tectum and Tiguan. These parts receive information from the outer area and send it to the cerebrum. The hindbrain consists of three parts, the medulla oblongata cerebellum and pons, where the cerebellum controls the balance of our body. The medulla oblongata controls involuntary actions like a breeding heartbeat, etc.
