5. Blood cell formation - in marrow cavities of certain bones (hematopoiesis)
How many bones do adult have?
Dense bone that looks smooth and homogenous
Bone composed of small needlelike pieces of bone and lots of open space

Open (Compound) Fracture
Fracture in which bone breraks into many fragments. Particularly common in the aged, whose bones are more brittle.
Fracture in which bone is crushed. Common in porous bones.
Fracture in which broken bone portion is pressed inward. Typical of skull fracture.
Fracture in which broken bone ends are forced into each other. Commonly occurs when one attempts to break a fall with outstretched arms.
Fracture in which ragged break occurs when exccessive twisting forces are appplied to a bone. Common in sport fractures
Fracture in which bone break incompletely. Common in children, whose bones are more flexible than those of adults
Four steps of bone fracture repair:
1. Hematoma (blood-filled swelling) is formed.
2. Fibrocartilage callus formation
3. Bony callus formation
4. Bone remodeling
