ends in puberty, Bones are continually remodeled in response to two factors, Pull of gravity and muscles on the skeleton, Break down bone matrix for remodeling and release of calcium in response to parathyroid hormone, Bone remodeling is performed by both osteoblasts & osteoclasts, ↑ Ca resorption from urine in kidney back into blood, = high blood calcium, decreases osteoclast activity, Bone Remodeling = depositing new bone matrix in a mature bone, In order to retain normal proportions & strength during long-bone growth, In order to form projections where muscles attach, Atrophy in bedridden or physically inactive people, abnormally increased size, excessive endochondral growth @ epiphyseal plates, person is abnormally small, improper growth @ epiphyseal plates, (bone + production + imperfect) – genetic disorders causing brittle bones with insufficient collagen; easily fractured, especially in fetus; poor healing/misalignment, Children with lack of calcium or Vitamin D in diet, bone marrow inflammation, can be caused by, (type of bacterium) through wounds or tuberculosis, (bone softness) – due to calcium depletion from bones; pregnancy or “Adult Rickets” from vitamin D deficiency, Closed (simple) fracture — break that does not penetrate the skin, Open (compound) fracture — broken bone penetrates through the skin, Bone fractures are treated by reduction and immobilization: realignment of the broken bone ends, : bones realigned via internal surgery and secured with pins/wires/plates, Note: joint immobilization during mid-late bone healing results in 3x decrease in strength, Bone not subject to the stresses that helps it form, Break is splinted by fibrocartilage to form a callus, Fibrocartilage callus forms;
