The Human Brain

The human brain is a marvelous organ that has the master control of all the other organs in our body. It has the ability to control almost every facet of the human body ranging from as simple as responding to a needle’s prick to solving the most complex problems. The human brain has got supreme cognitive functionalities which make humans the most evolved species. A human brain works by sending and receiving signals through neurons across various parts of the body.

It is the most complex structure with several folds. Along with the spinal cord, it accounts for a well operated central nervous system. 

Parts of the Human Brain

Several folds of the brain are divided into various compartments. Each compartment performs its designated functions. The different parts of the human brain are:

  • Forebrain

  • Midbrain

  • Hindbrain

The forebrain consists of the Cerebrum, Thalamus, and Hypothalamus, which is why it is also the part that controls thinking and voluntary actions. It is the biggest part associated with higher brain functions and has 4 different lobes. They are:

  1. Frontal lobe

  2. Occipital lobe

  3. Parietal lobe

  4. Temporal lobe

The midbrain is a link between the forebrain and the hindbrain. It transmits signals between the midbrain and hindbrain. It is also associated with motor control, vision, hearing, temperature regulation, alertness, etc.

The hindbrain is involved in controlling visceral organs. Thus, it controls the heart rate, breathing, blood pressure, sleep and waking up functions, etc. It is composed of the medulla oblongata, pons, and cerebellum.

Let’s look at some solved MCQs on the human brain for NEET.
