Structure of Long bones

Compact bone tissue

Dense; protective exterior tissue

Spongy bone tissue

cancellous; deep and pourous tissue

Diaphysis

Body of bone or shaft

Medullary Cavity

central cavity within diaphysis

Endosteum

thin layer of connective tissue lining medullary cavity

Yellow Bone Marrow

lipid storage in medullary cavity

Ephiphysis

each end of diaphysis, consists of spongy bone surrounded by a layer of compact bone

Red bone marrow

found in chambers of spongy bone and produced red blood cells, white blood cells and platelets

Erythropoesis

production of red blood cells

Articular cartilage

thin layer of hyaline cartilage that caps each end of the epiphysis and facilitates joint movement

Nutrient foramina

small openings in bone that allow for passage of nutrient vessels for nourishment of living tissue

Epiphesal plate

cartilage between diaphysis and epiphysis which is the region of mitotic activity and responsible for linear growth

Epiphyseal line

replaces the plate as ossification occurs

Periosteum

dense regular connective tissue covering the surface of bone that is highly vascular, the place of muscle and tendon attachment, and responsible for appositional growth (increase in width)

Perforating fibers

bundles of collagenous fibers securing the periosteum to the bone
