Understanding What the Brain Is Made Of
The brain is made of billions of specialized cells and structures that work together to control everything you do. It manages thoughts, emotions, movement, and memory.
Neurons: The Communication Cells
Neurons are the main cells of the brain. They send electrical and chemical signals to each other, creating pathways that allow you to think, learn, and react.
Glial Cells: The Support Team
Glial cells protect neurons, deliver nutrients, clean waste, and keep everything stable. They are essential for brain health and fast signal transmission.
What the Brain Is Physically Made Of
The brain is about 75% water and also contains fats, proteins, sugars, and minerals. Fatty tissue helps insulate neurons, making signals travel faster.
Major Brain Structures
Key parts include the cerebrum for thinking, the cerebellum for coordination, and the brainstem for essential functions like breathing and heartbeat.
Why Brain Composition Matters
The balance of cells, water, and nutrients keeps the brain functioning properly. Even small changes can affect mood, memory, and decision-making.
The Simple Takeaway
The brain is made of neurons, glial cells, water, and essential nutrients. These components work together to power every thought, movement, and emotion.
