What Are the Functions of the Brain?

The brain is the command center of your entire body. It controls everything you do—thinking, breathing, walking, feeling, and even sleeping. It sends and receives messages using tiny cells called neurons. These neurons form trillions of connections, making the brain like a super-powered computer that never shuts off.

The brain is part of the central nervous system (CNS), along with the spinal cord. It’s protected by the skull and cushioned by fluids to keep it safe.

đź§  The Major Parts of the Brain

The brain has three main parts, and each one plays a special role:

Brain PartMain JobExample
CerebrumThinking, memory, senses, movementSolving a math problem
CerebellumBalance, coordination, fine motor skillsRiding a bike
BrainstemControls automatic body functionsBreathing, heart beating
  • The cerebrum is the biggest part and is divided into two halves called hemispheres.
  • The cerebellum sits in the back, just under the cerebrum.
  • The brainstem connects the brain to the spinal cord and keeps vital functions running without you thinking about them.

đź§­ Brain Functions by Region

The cerebrum is split into four lobes, and each has its own job.

Frontal Lobe

  • Controls decision-making, planning, problem-solving, and movement.
  • Helps you stay focused in class or kick a soccer ball.

Parietal Lobe

  • Handles touch, pressure, and spatial awareness.
  • Helps you feel your backpack straps or know where your pencil is without looking.

Temporal Lobe

  • Processes hearing and language.
  • Helps you understand what your teacher is saying.

Occipital Lobe

  • Deals with vision.
  • Helps you see and recognize shapes, colors, and faces.

📡 How the Brain Communicates

The brain sends signals through neurons, which pass messages using electrical and chemical signals. These signals travel at lightning speed—up to 250 miles per hour! 🧨

Here’s how the process works:

  1. A neuron picks up a signal.
  2. The message travels down the axon (like a wire).
  3. It jumps across the synapse to the next neuron using chemicals called neurotransmitters.

This system allows the brain to control muscles, react to pain, and understand everything happening around you.


đź§Ş Fun Brain Facts

Here are some awesome facts that show just how cool your brain really is:

đź§  Your brain has about 86 billion neurons!
⚡ Each neuron can connect to thousands of others.
🔋 The brain uses around 20% of your body’s energy—even while you sleep.
🧊 It feels no pain itself—even though it controls how you feel pain.
🧬 Your brain is about 75% water but works faster than any supercomputer.

Even though the brain only weighs about 3 pounds, it’s one of the most powerful organs in the human body.


🎯 Final Thoughts

The brain is the most important organ when it comes to controlling your body. From thinking and talking to walking and breathing, it handles it all. By learning about the parts of the brain and what they do, you can better understand how amazing your body really is.

Whether you’re playing a video game, solving a puzzle, or simply blinking your eyes, your brain is always working behind the scenes. Treat it well—get enough sleep, eat healthy foods, and keep learning. Your brain loves challenges!
