BONY LANDMARKS, , There are more than 200 bones in the human body. Each one is different and unique. Bone, landmarks help us describe individual bone with all of its bumps, ridges, and holes. In this, eBook, we will look at common bone landmark terminology.

Gross anatomy of a bone, There are two main parts of the bone:, the diaphysis and epiphysis., Diaphysis: The walls of the diaphysis, are composed of dense and hard, compact bone. It contains a hollow, region called the medullary cavity,, which is filled with yellow marrow., The cavity is lined with endosteum, where bone growth, repair, and, remodeling occur., Epiphysis: The wider section at each, end of the bones, filled with spongy, bone.

Gross anatomy of a bone, Between the diaphysis and the epiphysis, is the epiphyseal growth plate, which, contains hyaline cartilage in a growing, bone. Once the bone stops growing, the, cartilage is replaced by osseous tissue, and the plate becomes a line., The outside of the bone is covered, in a fibrous membrane called the, periosteum. This contains blood, vessels, nerves, and lymphatic vessels., Tendons and ligaments attach to the, bone here. When bones meet to form, a joint, the epiphysis of each bone is, covered with articular cartilage,, which reduces friction and acts as a, shock absorber.
