Document Summary

Bone tissue: bone: organ made up of several different tissues working together, bone tissue, cartilage, dense ct, epithelium, adipose tissue and nervous tissue, skeletal system: bone and cartilage, bone tissue is constantly remodeling. 4: osteocytes: mature bone cells, osteoclasts: helps with resorption of bone. Spongy bone tissue: no osteons, interior of the bone. 6: supply red bone marrow and bone tissue. Fractures: any break in a bone, stress fracture: series of microscopic fissures in bone, formed without any evidence of injury to other tissues, treatment goals are realignment, immobilization and restoration, repair. 9: reactive phase: blood clot forms around fracture (hematoma), bone cells die and phagocytes and osteoclasts start to remove them, reparative phase: fibrocartilaginous callus (becomes spongy bone) and bony callus, bone remodeling phase. Exercise and bone tissue: under stress, bone tissue deposits mineral salts and collagen and remodels. 11: high-impact stimulates more bone remodeling than low-impact.
