How is spinal cord protected from injuries?
Bones, discs, ligaments, and muscles all work together to protect the spinal cord. 33 bones, or vertebrae, make up the spine. Each vertebra has a hole in the middle known as the spinal canal through which the spinal cord travels. Discs that serve as cushions or shock absorbers for the spine are located between the vertebrae.
Why does the brain needs a continuous supply of blood and oxygen?
The brain has top priority for the blood because brain cells will perish if the supply of blood that carries oxygen is cut off. The body tries to keep the brain supplied with blood even when other organs are in need of it. Many components that the brain needs to function properly are carried by the blood.
What happens if all functions of human body is controlled by brain?
Solution: 1) Our bodies will suffer damage in dangerous circumstances if the brain controls all bodily functions.
2) Our brain may be unable to carry out reflex actions, which call for immediate response to a stimulus, because some actions may be delayed.
Why is it important to protect the brain?

Which side of brain is memory?
Our brains are divided into two halves, or sides. Language abilities are typically located on the left side of the brain in people. The right side governs problem-solving, reasoning, memory, and attention. Problems with these critical thinking abilities may result from RHD.
