Have you ever wondered how you are able to see, hear or touch something? How about emotions? What about why you have memory? There is a simple, two-word answer to these questions: THE BRAIN. The brain is an organ that is protected by the skull. It is like the control center for your body.
HERE ARE SOME FUN FACTS!
The brain weighs about 3 pounds and has three parts: the cerebrum, the cerebellum, and the brain stem.
The cerebrum’s frontal lobe controls higher level functions, such as personality and intelligence. The parietal lobe controls your sense of touch and attention. The occipital lobe focuses on vision. The temporal lobe aids memory and hearing.
The cerebellum assists with coordination. The brain stem controls involuntary actions such as breathing and cardiac function. The hippocampus, located in the medial temporal lobe, is associated with long term memory.
A bunch of thick nerves allow the left and right hemispheres of the brain communicate with each other, since they are separated by a ridge.
The brain stem is a lower extension of the brain and is connected to the spinal cord.
HOW DOES THE BRAIN WORK?
The brain works by sending and receiving messages through cells called neurons. Neurons consist of a cell body, an axon, and dendrites. The cell body is the center of receiving and sending impulses. The axon is a long, thin fiber, and is the method of communication. It carries the impulse down to the cell body of another neuron and sends the message.
The brain is an exciting field of study, and it is fun to learn about. Remember, the possibilities are endless!
