To help you remember the different components of the human brain, you can use these simple mnemonics:

• Cerebrum (The "Big Room"): Since it makes up $75\%$ of the brain's volume, think of it as the biggest 'room' in your head where all your thoughts, logic, and sensory processing happen.

• Cerebellum (The Balance "Bell"): Imagine a tightrope walker holding a bell while they walk. This part of the brain is responsible for your coordination and balance.

• Brain Stem (The "Stem" of life): Think of a flower's stem. Just as the stem is vital for keeping the flower alive, the brain stem controls your most basic life functions, like breathing and heart rate.

• Meninges (The "Men-in-gear"): Think of 'men in gear' (like bodyguards in armor) protecting the brain. These are the protective layers surrounding your brain and spinal cord.
