Our skeletal system is made up of 206 bones. These bones work together to provide our body with support so that we can stand, help us to move so we can walk around, and protect our vital organs like our heart and our brain. Our bones even make and store blood cells for our circulatory system. Without our bones we would be only a pile of skin, organs, and muscles on the floor. Kind of like a jellyfish. We wouldn’t be able to move and our organs wouldn’t be safe.
Our bones are made up of many layers. These layers each have a different purpose and are important and dense. The next layer of bone is called cancellous bone (a.k. a. spongy bone). This layer allows our bones to be lightweight and transitions us from compact bone into bone marrow. Bone marrow is a thick and spongy section in the middle of bone where red blood cells and white blood cells are formed. Finally our bones are all covered in a thin membrane called periosteum which is where our muscles attach to bones. So that is how bones are structured in order to keep our bodies strong, yet lightweight.
Although bones are extremely important, we wouldn’t be able to move without joints. Joints are places where two or more bones meet. There are several types of joints in our body, but we’ll just focus on four of them. The first type of joint is called a...
I, Thomas Muller, as a physiologist will need to focus especially on the problem of our muscles degenerating. Mars' gravity is only 38% percent (about 1/3) of Earth's and as a result our muscles will get used to not have to work against gravity so much and they will get gradually weaker. This is a big problem as we will not have strong legs. I was thinking up solutions for this problem and I have found a few that are worth mentioning. First, I weighted vest custom fit and made for each citizen. The citizen will wear this vest and it will simulate gravity similar to that on earth. Also a vest with neodymium magnets in specific spots could also work. Second the Combined Operational Load Bearing External Resistance Treadmill (COLBERT) designed by NASA will take the place of the weighted vest on some days. I am very excited to be going to Mars as I am essential to the mission. I love being the first to do something.
