Unit 6 was all about the skeletal system. First, we learned about the different types of bones, what bones are made of, and how they repair themselves. The axial bones are the bones that make up our foundation and protect our organs. The appendicular bones help us with movement. Bones are classified by their shape: long, short, flat, and irregular. The two types of bone tissue of bone are compact and spongy. The cells that are responsible for bone remodeling are osteocytes, osteoblasts, and osteoclasts. Osteoblasts are bone forming cells and osteoclasts are bone destroying cells. Next, we learned about the disorders of the skeletal system like arthritis. Osteoporosis and rickets are caused by a deficiency in vitamins and minerals. We also learned about kyphosis, lordosis, and scoliosis which are all diseases relating to an abnormal curvature of the spine. Lastly, we learned the names of all the bones and the different kinds of joints.
I want to learn more about the cures for bone diseases, if any. Do you have to live with the disease forever or are some of the diseases reversible? For example, osteoporosis is by loss of minerals in the bones, making them more brittle. Does this mean a person with osteoporosis just needs to have more minerals in their diet or is there something more? I would also like to learn more about the similarities and differences between human bones and other animal bones because of the owl pellet lab. So far this semester has been going well and I've been keeping up with my New Years goals.
