How does the skull protect your brain when hit in head?

1. Cushioning effect: The skull is made up of thick bone, which acts as a hard, protective barrier around the brain. When the head is hit, the skull absorbs and distributes the force of the impact, preventing it from reaching the brain directly.

2. Shape of the skull: The shape of the skull also plays a role in protecting the brain. It is rounded and smooth, without any sharp edges or protrusions that could cause damage to the brain upon impact.

3. Fluid-filled spaces: The brain is surrounded by cerebrospinal fluid (CSF), which acts as a shock absorber and helps to cushion the brain against impact.

4. Meninges: The brain and spinal cord are covered by three layers of protective membranes called the meninges. These membranes add an extra layer of protection and help to keep the brain in place within the skull.

5. Blood-brain barrier: The brain has a unique network of blood vessels called the blood-brain barrier, which helps to regulate the flow of blood and protect the brain from harmful substances.

6. Skull sutures: The skull is made up of several bones that are connected by sutures, which are flexible joints. These sutures allow the skull to absorb and dissipate impact forces more effectively.

Overall, the skull provides a strong and protective environment for the brain by absorbing and distributing impact forces, cushioning the brain with fluid-filled spaces, and preventing sharp objects from penetrating the brain.
