How We Get Our Strength to Move (and do whatever)

Every time we wake up, stand up, sit down, write a letter, pick up a toothbrush, and jot down notes on a wild animal, we move. But how do we get our strength to move, and is it automatic? There is a complicated answer to this question-and it could answer some other questions as well.

In every single part of your body, you have muscles. Under the muscles are the bones which also help you flex. In this picture:

muscles

You can see that muscles can help support the skeleton in bending your limbs, as they flex deflex Although deflex isn’t a word, you know what I mean. In the bones:

They are the things that actually make you move. Near the patella (end of upper leg bone) you can see that there is a little gap there. Between there is an oil-like substance called cartilage. It helps you move your limbs without the bones scraping on each other to create a cavity in your bones, or make them smaller. With the muscle’s support, it make us who we are today: able to lift up 50 pound weights (some people), and able to type a letter. It is the bones and muscles that help support the body from moving.

The final part is the brain. The brain tells your body on what muscle to flex and what bone to move to make the pose that it desires. Without the brain, nothing works. Not even you will be able to move anything, because nobody’s telling you to.

It brings me to another examination saying, “What would happen if there was no brain?” I would ponder about this question, and not find an answer. So science still has some work to do with us, I guess.
