Osteoarthritis is a joint disease that mostly affects cartilage. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage allows bones to glide over each other. It also helps absorb shock of movement.
In your body, you have only two types of bone tissue: cortical and cancellous bone. In this lesson, we will learn about the structure and function of cancellous bone, which plays a crucial role in producing blood cells and stem cells and is the primary tissue affected by osteoporosis.ecause osteoclasts live on the surface of bone tissue and cancellous bone has a much larger surface area than cortical bone, it is the primary bone tissue affected by osteoporosis. In healthy people, bone is constantly being remodeled as osteoclasts break down old, damaged bone and osteoblasts replace it.
