✨hey mate!✨

First of all the brain sits inside the skull and the spinal cord is surrounded by a series of vertebrae. Inside these bony structures lie a series of layers of tissue referred to as meninges.

These meninges surround the brain and spinal cord, and act as a protective lining adding additional layers of protection. Within the layers of the meninges is a channel referred to as the subarachnoid space and, within this space the cerebral spinal fluid (CSF) runs. This fluid is constantly recycled through the meninges and spaces within the brain called ventricles.

The brain in effect "floats" in the cerebral spinal fluid, so that the CSF greatly reduces the net weight of the brain on the base of the skull, and acts to protect the brain from blows to the head.

hope it is helpful!✌️
