BONE COMPOSITION

Familarize yourself with the composition of compact bone, the bone of the skelton, key structures (markings) of compact bones, and the knee joint.

Compact Bone

Hard, dense, outer layer of bone

Cancellous Bone

Spongy, soft, Inner layer of bone

Nutrient Foramen

small opening or canal in the bone that allows blood vessels and nerves to enter and nourish bone tissue.

Where are Long bones in a Human Skeleton?

(LONG BONE)  Diaphysis

Shaft/Central part of long bone

(LONG BONE) proximal and distal

rounded ends or tips of long bone

(LONG BONE) Epiphyseal line

Thin line, at the ends of the Long bone

(LONG BONE) Medullary cavity

Hollow space within diaphysis.

(LONG BONE) Articular Surface

A joint— where epiphyses of bones meet

(LONG BONE) Periosteum

Protective sheath that covers compact bone 

Where are Flat Bones found on a Human Skeleton?

(FLAT BONE) Diploë

Cancellous bone found in flat bone 

(FLAT BONE) Osteons

Layered in Compact bone

(FLAT BONE) Central (Haversian) Canals

Hole in the center of Osteons

Volkmann’s (perforating) canal

allows blood vessels and nerves to connect the outer part of the bone

(FLAT BONE) Lamellae

Thin layer of bone, around Haversian canal

(FLAT BONE) Lacunae

Small spaces that have osteocytes

(FLAT BONE) Canaliculi

Tiny Channels (Holes) in Bone tissue
