Types of bones

This tutorial by Matt from Ken Hub explores the five types of bones in the human skeleton: long, short, flat, sesamoid, and irregular. Each type is described by its form and shape. Long bones, such as the femur and humerus, have a complex anatomy and develop through endochondral ossification. Short bones, like carpal and tarsal bones, are cuboid in shape. Flat bones, including the skull and ribs, have two layers of compact bone. Irregular bones, such as vertebrae, are categorized by content. Sesamoid bones, like the patella, protect tendons from wear.
