The Human Brain



How do you remeber the way to school? Where do dreams come from? How do your eyes blink without you telling them to? Your brain is in charge of these things and SO much more. Your brain is really the boss of your body. It runs the show and controls nearly everything you do. Not bad for something that looks like a big, slimy ball of wrinkles!

Your brain has many different parts that work together, however there are 5 distinct parts that do most of the work. These parts include the cerebrum (does the "thinking" and controls your voluntary muscles), the cerebellum (controls balance, coordination, and movement), the brain stem (in charge of the functions your body needs to stay alive - breathing, digesting, etc.), the pituitary gland (controls growth), and the hypothalmus (controls your inner thermostat).

With such important jobs it is crucial to take extra special care of it. Some tips to keep your brain in good shape include:

-Eat healthy foods. They contain potassium and calcium, two minerals that are important for the nervous system.
-Get a lot of exercise.

-Wear a helmet when you ride your bike or play other sports that require head protection.
-Don't drink alcohol, take drugs, or use tobacco.
-Use your brain by doing challenging activities, such as puzzles, reading, playing music, making art, or anything else that gives your brain a workout!

Welcome!

Hello, hello!

Welcome to my blog. This blog is all about our ever complex and interesting human bodies. The human body is an absolutely amazing thing... it blows my mind that there are so many things going in your body at all times and we don't even think about it or realize that they are going on.

Let me take a moment and introduce myself. My name is Christina and I am a sophomore at Purdue University in West Lafayette, Indiana. I am studying elementary education and cannot wait to have a classroom of my own some day.

Some facts about the human body that you may not know...:
  • The only jointless bone in your body is the hyoid bone in your throat.
  • Your stomach needs to produce a new layer of mucus every two weeks or it would digest itself
  • Human thigh bones are stronger than concrete.
    When you sneeze, all your bodily functions stop even your heart.
  • Our eyes are always the same size from birth, but our nose and ears never stop growing.
    In the average lifetime, a person will walk the equivalent of 5 times around the equator.
  • The average surface of the human intestine is 656 square feet (200 m).
  • The human heart creates enough pressure to squirt blood 30 feet (9 m).
  • Every human spent about half an hour as a single cell.
  • Human blood travels 60,000 miles (96,540 km) per day on its journey through the body.
  • The average human heart will beat 3,000 million times in its lifetime and pump 48 million gallons of blood.

Amazing, huh? :)
