The brain is protected by a bony box in the body. This box contains the brain and is filled with fluid, which provides additional shock absorption.
The brain is safeguarded by several protective mechanisms. The skull, a rigid bony structure, encases and shields the brain from external trauma. The meninges, three layers of membranes surrounding the brain, provide additional protection. Cerebrospinal fluid, circulating within the subarachnoid space, acts as a cushion, absorbing shock and reducing impact forces. The blood-brain barrier regulates the passage of substances between the bloodstream and the brain, preventing harmful agents from entering. Together, these defenses create a robust protective environment, shielding the delicate neural tissue from physical damage, infections, and fluctuations in the body’s internal environment.
