Meet the Organs!

Hi there. I’m your brain – the boss of your body!  Without me, you wouldn’t know what to think, do, eat or drink! I control practically everything that you do – even when you’re asleep! 

The biggest part of the brain is the called the cerebrum. This is the thinking part and controls your voluntary muscles – they’re the ones that move when you want them to. You also use this part of the brain when you’re trying to solve a puzzle or spell a difficult word.  It’s also where your memory lives – both new memories and old ones. It is split into two halves: the left side controls the right side of the body and the right side controls the left side of the body.

The cerebellum is found at the back of the brain, below the cerebrum. It’s much smaller than the cerebrum – about one eighth of the size. Here, balance, movement and co-ordination is controlled.

Underneath the cerebrum and in front of the cerebellum is the brain stem. Although it may seem small, it is very significant, as it has the crucial job of connecting the rest of the brain to your spinal cord, which runs down your neck and back.  The brain stem looks after breathing, eating food and moving blood around the body.

The brain stem also controls your involuntary muscles – these are the ones that work automatically, without you having to think about it – like making your heart pump more blood when you’re running.  Similar to a bridge between the brain and the body, the brain stem sorts the millions of messages that pass forward and back between body and mind.

I also have a thermostat inside me, called the hypothalamus. This controls your body temperature (normally around 37oC).  If your body is too cold, the hypothalamus makes it shiver to get warm and when you get too hot, it makes your body sweat to cool it down.

I also have another very important job – I’m control your feelings and emotions … like when you feel angry or sad. I hope you feel happy now that you know me that little bit more. And thanks for stopping by!
