The musculoskeletal system is one of the most important systems in the human body. It provides a frame for the body not only in order to protect and support our vital internal organs, but also helps to provide movement for the body through our bones, joints, and muscles. This complex system goes through great changes as we grow older from birth to adulthood. It will also eventually dictate what our general physical make-up will be once we reach full adulthood. There are two-hundred and six bones in the human body. Most people think we need to grow and reach full adulthood before we have the two-hundred and six, but the truth is that when we are born, we have all of these bones, only they are less dense and smaller in size. As we grow older some of these bones grow in length and in thickness.

This is the primary change which occurs from childhood to adulthood. There are also changes that occur in the density of our bones as we get older which is why “physicians pay close attention to that in elderly patients because calcium and vitamin D supplementation helps to maintain the density and strength of the bones”. (Galamaga, 2012). Some people think that when the body changes through growth that new bones are formed. In actuality, this does not occur. When we are born all of our bones are there but in very tiny forms. During fetal development, the bones in the fetus are made up of what is called cartilaginous tissue or flexible tissue, than as we get older this gradually gets replaced by ossification or bone formation. In conclusion, the musculoskeletal system is an amazing and multifaceted system that, without it, we would be reduced to blood, water, and flesh. It allows our bodies to stand upright, protects our vital organs, and is the reason we have movement in our joints.
