Bone Structure and Growth Concepts

Bones

Periosteum

Epiphysis

Compact bone

Articular cartilage

The periosteum is a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

The medullary cavity is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow is stored.

Spongy bone is a type of bone that has a porous structure and is found at the ends of long bones and in the interior of others.

Osteoblasts are cells that synthesize bone and are responsible for bone growth.

The epiphyseal plate is a hyaline cartilage plate in the metaphysis at each end of a long bone, responsible for the lengthwise growth of the bone.
