Together, the brain and spinal cord form the central nervous system. The brain is protected by the bones of the skull and by a covering of three thin. It is located in the head and is protected by the boney covering called the skull. Together, the brain and spinal cord are known as the central nervous system. The central nervous system (CNS) is the part of the nervous system consisting of the brain and In vertebrates, the brain is protected by the skull, while the spinal cord is protected by the vertebrae. The brain and spinal cord are both enclosed.

Impact of this question views around the world. For further protection, the brain is encased within the hard bones of the skull, while the spinal cord is protected with the bony vertebrae of our backbones.
A third form of protection is cerebrospinal fluid, which provides a buffer that limits impact between the brain and skull or between spinal cord and vertebrae. In terms of tissue, the CNS is divided into grey matter and white matter. Grey matter comprises neuron cell bodies and their dendrites, glial cells, and capillaries.
White matter refers to the areas of the CNS which host the majority of axons , the long cords that extend from neurons. Most axons are coated in myelin - a white, fatty insulating cover that helps nerve signals travel quickly and reliably. In the brain, white matter is buried under the grey surface, carrying signals across different parts of the brain. In the spinal cord, white matter is the external layer surrounding the grey core. If the CNS is the processing centre of the human body, the brain is its headquarters.
It is broadly organised into three main regions - the forebrain , the midbrain , and the hindbrain. The largest of these three is the forebrain derived from the prosencephalon in the developing brain.
How is the central nervous system protected from injury?
The central nervous system (CNS) consists of the brain, spinal cord, spinal fluid and They instead serve to protect and nourish the neurons. The brain is protected by the skull (cranium), cerebrospinal fluid and 3 protective membranes (Meninges). The spinal cord is protected similarly. The CNS is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of.
