How does structure relate to function in the bone cells?
the basic components of a typical long bone: articulartory (also known as ‘articular’) cartilage; spongy bone; bone marrow; endosteum; compact bone; periosteum; medullary cavity, and a blood vessel (indicating blood supply and circulation within bones). Articulatory (or articular) cartilage reduces friction and absorbs shock at freely moveable joints. Endosteum is the membrane that lines the cavity of a bones. Periosteum is a tough fibrous membrane that surrounds the outside of bones wherever they are not covered by articulatory cartilage. In adults the medullary cavity contains fatty yellow bone marrow. Bones grow from their ends (extremities). Under normal circumstances bones stop growing when the owner reaches his.her late teens or early twenties. Bone marrow (see diagram below) produces stem cells, such as erythrocytes (red blood cells) and leucocytes (white blood cells). main types of bone tissue: Compact (also known as “compact”) tissue forms the outer shell of bones. It consists
