Document Summary

Structure: three main parts to a bone: Thick fibrous vascular membrane covering the bone surface. Predominant in long ends of the bone. Hemopoietic or stromal: can develop into red blood cells or produce bone, red marrow and yellow-marrow adults tend to have more yellow (adipose) Primarily in flat bones (hip, breast, rib, shoulder, vertebra: bone structure. Take free calcium and phosphorus plus collagen to form hydroxyapatite- bone mineral. Bone cells that break down cone and release bone minerals to blood: calcium, vitamin d, phosphorus. Concentration of minerals found in bone and used as an indicator of. Bone health factors bone health: trabecular bone more responsive to influential factors than cortical-bone remodeling speed, biological or lifestyle. Frame size: larger frame = higher peak bone mass than smaller framed individuals. Hormone balance: estrogen (men and women location will vary, huge contributor to bone maintenance specifically osteoblast activity, nonmenstruating or those who have lost menstrual for 3 consecutive months should see a doctor.
