Answer 2

Answer:

Ritika was hit by a football on her head but did not suffer from any serious injury because the brain is protected by the bones of the skull and a covering of three thin membranes called the meninges. It is also protected and cushioned by cerebrospinal fluid. This watery fluid is produced by special cells in the four cavities of the brain called the ventricles. It flows through the spaces between the ventricles and the meninges. Cerebrospinal fluid can also brings nutrients from the blood to the brain and it can removes waste products from the brain.

The spinal cord consists of bundles of nerve fibers. It runs down from the brain through a canal in the middle of the bones of the spine. These bones can protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and softened by cerebrospinal fluid.

Spinal nerves connect the brain to nerves in most parts of the body. Other nerves go directly from the brain to the eyes, ears, and other parts of the head. This neural network carries messages back and forth between the brain and the rest of the body.
