The brain is protected by being enclosed in a bony box, and within this, it is surrounded by a fluid-filled balloon, which acts as an additional layer for shock absorption.
How is the brain protected in the human body, and what provides additional shock absorption for the brain?

The human brain is protected by the skull, a bony structure that encases and shields it from external impact. Additionally, three layers of meninges, protective membranes surrounding the brain, provide further insulation. Cerebrospinal fluid (CSF), found within the subarachnoid space between the meninges, acts as a cushion, absorbing shocks and providing buoyancy to the brain. This combination of the rigid skull, meninges, and cerebrospinal fluid serves as a comprehensive protective system, safeguarding the delicate and vital organ from mechanical injuries and shocks within the dynamic environment of the human body.
