Osteology

The metaphysis (/mətˈæfᵻsᵻs/) is the wide portion of a long bone between the epiphysis and the narrow diaphysis.

Osteoblast (from the Greek combining forms for "bone", ὀστέο-, osteo- and βλαστάνω, blastanō "germinate") are cells with a single nucleus that synthesize bone.

The diaphysis (/daɪˈæfᵻsᵻs/) is the main or midsection (shaft) of a long bone.

The epiphysis (/ɛˈpɪfᵻsᵻs/) is the rounded end of a long bone, at its joint with adjacent bone(s).

In anatomy the endosteum (plural endostea) is a thin vascular membrane of connective tissue that lines the surface of the bony tissue that forms the medullary cavity of long bones.

The osteon or haversian system /həˈvɜːr.

Hyperostosis is an excessive growth of bone.

An osteoclast (from the Greek words for "bone" (ὀστέον), and "broken" (κλαστός)) is a type of bone cell that breaks down bone tissue.

Osteomyelitis (OM) is infection and inflammation of the bone and bone marrow.

An osteocyte, a star-shaped type of bone cell, is the most commonly found cell in mature bone tissue, and can live as long as the organism itself.

The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone.

Periosteum is a membrane that covers the outer surface of all bones, except at the joints of long bones.

Cancellous bone, synonymous with trabecular bone or spongy bone, is one of two types of bone tissue that form bones.

Cortical bone, synonymous with compact bone, is one of the two types of osseous tissue that form bones.

Osteochondropathy refers to a disease ("-pathy") of the bone and cartilage.

Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones and release the minerals, resulting in a transfer of calcium from bone tissue to the blood.
