Today in science class I have learned a little about the skeletal system of the human body. Now, there are many functions of the skeletal system. Bones are made of Osseous tissue. The Osseous tissue forms the "rigid part of the bones that make up the skeletal system." There is also support and protection which is the most important functions. The supporting function is important because "the bones provide a framework or skeletal connection for the attachment of muscles and other tissues." So, basically, this function keeps the bones and tissues together. The protection function is for the bones such as the skull and rib cage, to protect, the vital organs from injury and "the bones also protect the marrow." Another function is body movement and blood cell formation. The last function I learned was that their is the "storage of inorganic materials," this means where all your calcium, vitamins, and other things store in your body.
There are 206 bones in the human body. The two main skeletal parts of the body is the Axial and the Appendicular.
- Axial- the Axial part of the body has 80 bones. The Axial consists of the vertebral meaning upper column such as the rib cage and skull. This Axial part of the body helps humans maintain their upright posture or otherwise we would be slouching.
- Appendicular- the Appendicular part of the body has 126 bones. And did you notice that both the Axial and the Appendicular both add up to 206 bones? Anyways, the Appendicular forms the pectoral girdles which is the upper limbs, and also forms the pelvic girdle, the lower limbs. The upper limbs include the bones of the arms and hands.The lower limbs include the leg and foot bones. This Appendicular part of the body is made to make humans run, walk, dance, sprint, whatever movement possible and also to protect the major organs in the body such as digestion, excretion (pooping and peeing), and reproduction.
