Chapter 2- Long Bones

Diaphysis

The long central shaft of a long bone, primarily composed of compact bone and containing the medullary cavity.

The Medullary Cavity

The central cavity within the diaphysis of long bones, filled with bone marrow and involved in the production of blood cells.

Epithelium

Lining of the body cavities and surfaces, consisting of one or more layers of cells.

The Endosteum

A deep, thin layer that lines the shaft on the bone and medullary cavity in the Diaphysis of Long Bones.

Epiphysis

The end parts of long bones where the Red Bone Marrow is found

Epiphyseal Line

The line that shows where the diaphysis and epiphysis parts of long bones were fused together after separate development.

The Periosteum

a superficial thin layer of dense connective tissue that encases the bones everywhere except at the joints

Articular Cartilage

Cartilage Found on the outer ends of the long bones (Epiphysis ends), and help bones glide past one another

Nutrient Foramina

Piercings where nerves and blood vessels travel through compact bones.

Perforating Fibers

Deep penetrations from the periosteum and lead to the bone matrix to help with attachment to the bones
