Types and Functions of Bones

The video tutorial discusses the six main types of bones: long, short, flat, irregular, sesamoid, and sutural. Each type is described in terms of its shape, location, and function. Long bones, like the femur, are longer than they are wide and contain bone marrow. Short bones, such as carpals, are cube-shaped. Flat bones, like the sternum, provide protection and muscle attachment. Irregular bones, including vertebrae, have complex shapes. Sesamoid bones, like the patella, develop in tendons. Sutural bones are small, irregular bones found in the skull.
