Trabecular bone is the sponge-like bone in the center of long bones and vertabrae.
Cortical bone is the hard outer shell of bones.
It is an accumulation of fractures in trabecular bone that are incompletely repaired that leads to the manifestation of osteoporosis.

 Bone Grafting   (Site not responding. Last check: 2007-11-01)
Bone osteogenesis is partially promoted by the cell activity of the surviving cells on the surface of the transplanted bone graft but mainly by the stimulation of osteoprogenitor cells in the host tissue (Urist, 1970, in Apley and Solomon, 1995, p.
Cortical or cancellous grafts are used when bone has been lost as a result of trauma or tumour removal.
Bone grafts may be attained for implantation in a variety of different forms to achieve the most effective graft.

Thus, the musculotendon unit distally for the biceps brachii is on the lateral bone of the forearm, that is-the radius.
Bones with a longitudinal emphasis are used as levers.
The upper extremity bones are lighter, as they are used for a greater range of motion, and actions such a manipulation of objects, and speed (a boxer throwing a knock out punch).

Transplant – The implantation of bone tissue, as in grafting, from one part of the body to another, or from one individual to another.
Vertebra – One of the 33 bones of the spinal column.
A cervical, thoracic, or lumbar vertebra has a cylindrically-shaped body anteriorly and a neural arch posteriorly (composed primarily of the laminae and pedicles as well as the other structures in the posterior aspect of the vertebra) that protects the spinal cord.

 WHFoods: Milk, 2%, cow's
For building bone, enjoying both milk and yogurt seems a good idea since lactoferrin's effects were found to be dose-dependent, stimulating an up to a 5-fold increase in osteoblasts at higher doses.
At the beginning and end of the study, DEXA (dual-energy X-ray absorptiometry) scans were run to check bone indexes of the hip, spine, and whole body, and the radius and tibia were checked by peripheral quantitative computed tomography.
Lactoferrin is a potent regulator of bone cell activity and increases bone formationin vivo.

 What is osteoporosis?   (Site not responding. Last check: 2007-11-01)
Osteoporosis is a disease of bone in which the amount of bone is decreased and the strength of trabecular bone is reduced, cortical bone becomes thin and bones are susceptible to fracture.
It is defined according to the bone mineral density (BMD) as measured by Dual Energy X-ray Absorptiometry.
