The human brain is the most complex organ in the human body. It is the center of the nervous system and controls the functions of the body. The average brain weighs about 1.4 kg (3.1 lbs) with a volume of 1130-1260 cm3. The brain is made up of, very soft, gray and white matter and is protected by the thick bones of the skull. If you have ever wondered just how many cells make up the brain, continue reading to find out.
How many cells are in the human brain?
There are still many things about the brain that we do not know. However, it is estimated that the brain contains somewhere between 80-120 billion nerve cells (neurons). These make up about 50% of the cells in a human brain so a general estimate for the amount of cells in a human brain would be somewhere between 160-240 billion cells. Most experts agree on a more specific estimate of 160-180 billion cells within the brain.
Did you know?
The number of cells in the brain is a subject for much debate. In fact, some experts do not agree with the above figure and argue that the neurons may make up much less than 50% of the brain. These experts argue that the number of glial cells (neuroglia) is underestimated and that they are the most numerous type of cell in the brain.
