Why does the brain needs a continuous supply of blood and oxygen?

The majority of the energy in the brain comes from an oxygen-dependent form of metabolism. However, neurons only store a small amount of energy, and these cells need a constant flow of oxygen, particularly when they are firing and interacting with one another.

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.

How does CSF protect the brain and maintain homeostasis?

CSF provides hydromechanical protection of the neuroaxis through two mechanisms. First, CSF acts as a shock absorber, cushioning the brain against the skull. Second, CSF allows the brain and spinal cord to become buoyant, reducing the effective weight of the brain from its normal 1,500 grams to a much lesser 50 grams.

Why are meninges called shock absorbers?

The meninges: Protect your CNS (central nervous system) from trauma injury to your brain, such as a blow to your head by acting as a shock absorber. They anchor your CNS and keep your brain from moving around within your skull.

What is mechanical shock in biology?

A mechanical or physical shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation.

What covers the surface of the heart?

The Pericardium. The pericardium is the fibrous sac that surrounds the heart. It can be divided into three layers, the fibrous pericardium, the parietal pericardium, and the visceral pericardium. The parietal and visceral pericardia together form the serous pericardium.
