This project is about the 4 bone cells in the human body. The red color is the osteoclast, and the blue is the osteoblast. Below them are the osteocytes, and the thin layer of yellow is the bone layer, or osteogenic cells. The first painting shows regular activity for these 4 bone cells. The second painting shows the effects of osteoporosis on the bone. It represents more osteoclast activity and osteocyte death inside the bone.
