Document Summary
Bone tissue: a bone is an organ made up of several different tissues working together: bone (osseous) tissue, cartilage, dense connective tissue, epithelium, adipose tissue, and nervous tissue. The entire framework of bones and their cartilages constitute the skeletal system: bone tissue is a complex and dynamic living tissue. It continually engages in a process called remodeling the building of new bone tissue and breaking down of old bone tissue. astronauts lost up to 20 percent of their total bone density during their extended stay in space. The zero-gravity (weightless) environment of space, coupled with the fact that the astronauts traveled in small capsules that greatly limited their movement for extended periods of time, placed minimal strain on their bones. The study of bone structure and the treatment of bone disorders is referred to as osteology. The skeletal system performs several basic functions: support.
