Welcome to the Skeletal System section of the Free Anatomy Quiz
There are 206 bones in a typical human body, providing an important range of functions. They :
Provide a framework that supports the body
Protect the organs within the body cavities against mechanical injury, e.g. the rib cage protects the heart and lungs, the skull protects the brain
Contain and protect the red bone marrow, where red blood cells (or erythrocytes), white blood cells (or leukocytes) and lymph cells are formed
Provide a storage site for inorganic salts such as calcium and phosphate
And by providing the site of attachment of muscles, they create a system of levers which can be used to create motion in the body
Each of the sections below contains quizzes on different areas of the skeletal system. If you work through the different sections regularly, you'll soon be able to remember the names and locations of every bone in the body!
