Question

How is the brain protected in our body?

Answer 1

The human brain is the main part of the human nervous system. It tends to make up the central nervous system, with the spinal cord.

Complete answer:
To answer this question, first, we need to know about the human brain and what its roles are in the human body. The human brain is the nervous system command centre. This receives signals from the sensory organs of the body and provides outputs to the muscles. The human brain has almost the same basic structure as other mammalian brains but is bigger than any other brain in comparison to the body size. It plays a role in every major system of the body.
Now, we will come to know how it remains protected in our body –
The brain is the organ in the body that is best protected. It has several protective layers beginning with the first protective layer being the skull or cranium, which serves as armor protecting the brain from hits. The next defensive layer is the meninges which have three membranes protecting the brain and spinal cord to prevent it from being affected by contact with the inside of the skull. The brain is also protected by a fluid called cerebrospinal fluid. Special cells in the four hollow spaces within the brain, called ventricles, produce this watery fluid. It flows in between meninges through the ventricles and in spaces.

Note: The human brain is protected by skull or cranium and meninges that contain three membranes. The skull is a bony structure in vertebrates that forms the head. It supports the face structures and gives the brain a protective cavity.
