This gland is a big player in puberty too. If your clothes from last year are too small, it's because your pituitary gland released special hormones that made you grow. The pituitary gland is very small - only about the size of a pea! Its job is to produce and release hormones into your body. Whew! It's a big job being the brain's secretary! Pituitary Gland Controls Growth The brain stem also sorts through the millions of messages that the brain and the rest of the body send back and forth. There are involuntary muscles in the heart and stomach, and it's the brain stem that tells your heart to pump more blood when you're biking or your stomach to start digesting your lunch. Part of the brain stem's job is to control your involuntary muscles - the ones that work automatically, without you even thinking about it. The brain stem is in charge of all the functions your body needs to stay alive, like breathing air, digesting food, and circulating blood. It connects the rest of the brain to the spinal cord, which runs down your neck and back. The brain stem sits beneath the cerebrum and in front of the cerebellum. What does he need most to stay balanced? The best surfboard? The coolest wetsuit? Nope - he needs his cerebellum! Brain Stem Keeps You Breathing - and MoreĪnother brain part that's small but mighty is the brain stem. Think about a surfer riding the waves on his board. It controls balance, movement, and coordination (how your muscles work together).īecause of your cerebellum, you can stand upright, keep your balance, and move around.
But it's a very important part of the brain.
The cerebellum is at the back of the brain, below the cerebrum. Scientists do know for sure that the right half of the cerebrum controls the left side of your body, and the left half controls the right side. The left half is said to be more analytical, helping you with math, logic, and speech. Scientists think that the right half helps you think about abstract things like music, colors, and shapes. The cerebrum has two halves, with one on either side of the head.

The cerebrum also helps you reason, like when you figure out that you'd better do your homework now because your mom is taking you to a movie later. Your memory lives in the cerebrum - both short-term memory (what you ate for dinner last night) and long-term memory (the name of that roller-coaster you rode on two summers ago). You need your cerebrum to solve math problems, figure out a video game, and draw a picture. So you need your cerebrum to dance or kick a soccer ball. The cerebrum is the thinking part of the brain and it controls your voluntary muscles - the ones that move when you want them to. The biggest part of the brain is the cerebrum.
