There are three things that protect the CNS; brain and spinal cord. Bone which is the skull for the brain and the vertebrae for the spinal cord, meninges which is a protective membrane, and the spaces between the meninges are filled with cerebrospinal fluid for cushion and protection.
The four fluid-filled cavities in the brain are called ventricles. They are interconnected and filled with cerebrospinal fluid, which helps to protect the brain and spinal cord, provide nutrients, and remove waste.
You just need 2 things- your brain and your eyes.
The hollow areas within the brain are called ventricles. There are four ventricles in the brain: two lateral ventricles, the third ventricle, and the fourth ventricle. These spaces are filled with cerebrospinal fluid which helps cushion and protect the brain.
The answer is "headache" because it is four things. On your head, in left/right eye and a word and it covers head pain on your head. It also teases your brain sort of to make it hurt.

Some interesting cranium questions to test knowledge of the human skull and brain include: What are the four major bones that make up the human skull? What is the purpose of the frontal lobe in the brain? How many cranial nerves are there in the human body, and what are their functions? What is the role of the cerebellum in the brain? Can you name the three layers of the meninges that protect the brain?
We consider the brain in four sections, or lobes, by area. Each lobe extends across both hemispheres (halves) of the brain. They are the frontal, temporal, parietal, and occipital lobes.
The cerebellum is not one of the four lobes in the hemispheres of the brain; it is a separate structure at the back of the brain that plays a key role in motor coordination and balance.
