Labeled parts of a human brain

This is a list of scientific brain facts for kids. The human brain is a critical part of the body that controls almost every function of the body. The human brain is unique in the animal world. It is highly advanced, can think, calculate, remember and reason. Humans are the not largest, fastest or strongest animals, but our brains give us capabilities that no other animals have. In recent years, scientists have made great advancements in learning about the human brain. There is, however, much that scientists do not understand about the human brain. Find out some brain facts for kids that scientists understand about the human brain.


  • The human brain controls almost all of the body's movements. The exception is reflex movements like blinking, knee-jerking and sneezing.

  • There are more than one billion neurons (nerve cells) in the human brain.

  • The brain has two sides also known as cerebral hemispheres. Each side has a different function. The left side of the brain helps us process words and helps with body motion. The right side of the brain helps us with art, music and colors.

  • Similar to the human heart, the brain has 4 chambers called ventricles.

  • The ventricles make a fluid called cerebrospinal fluid. This fluid is very important for good brain health. Every day each ventricle makes 12 oz (350 ml) which is used to "clean out" the brain. This fluid also protects the brain from hitting the skull when it is knocked around. Having too much fluid results in a condition called Hydrocephalus. Hydrocephalus can lead to brain damage, but can be treated, if detected.

  • The largest part of the human brain is the cerebrum, which is about 90 percent of the volume of the brain.

  • The brain connects to the spinal system with 31 pairs of spinal nerves. People that have an injury resulting in spinal nerve damage, often have permanent damage that doctors currently cannot repair. Nerve damage may result in issues with the brain communicating with the body.

  • brain spinal cord
