DXA may also be indicated based on risk factors including patient's age at fracture, severity of underlying conditions, exposures to radiation or drugs detrimental to bone, and family history. (medscape.com)
Accurate measurement of these skeletal parameters through the development of better imaging scanners is critical to advancing fracture risk assessment and informing clinicians on the best treatment strategy. (biomedcentral.com)

An osteon, the elementary unit of cortical bone, is a hollow cylinder made of a deformable porous matrix saturated with an interstitial fluid. (heightquest.com)
Osteocytes are found in cortical bone and not necessarily just beneath the periosteum. (heightquest.com)
[ 1 , 2 ] The remainder of the blood supply is through nutrient vessels that pierce the cortex and supply the marrow cavity and the inner two thirds of the cortical bone. (medscape.com)
The subchondral bone is not true cortical bone, in that it lacks some of the organization of cortical bone. (medscape.com)

The human skeleton is especially affected by the passage of time: bone loss begins as early as the third decade of life, immediately after peak bone mass. (biomedcentral.com)
There are two reasons for remodeling: firstly, it allows bones to adjust to the physical stress new activities put on the skeleton. (petrx.com)

Osteoclasts, which dissolve bone, and Osteocytes which play a regulatory role. (nutritiousandnice.com)

Although this definition is functionally valid for adults, it is not appropriate for children because they have not yet attained peak bone mass. (medscape.com)

Possibly, indicating the formation of new osteons in the epiphysis of the bone. (heightquest.com)
This, in turn would increase the levels of osteocalcin which is responsible for bone formation. (umc.edu)

There is bone on the surface of the ends of the epiphysis of the long bones. (heightquest.com)
Mature long bones have 3 distinct zones: epiphysis, metaphysis, and diaphysis (see the image below). (medscape.com)
The epiphysis is the region at the polar ends of long bones. (medscape.com)

Nevertheless, creating living tissues constructs that structurally are, functionally and mechanically equivalent to the organic bone fragments provides been a problem therefore considerably. (globaltechbiz.com)
Anabolic medications (teriparatide and abaloparatide) increase the periosteal and endosteal perimeters without large changes in cortical thickness resulting in a larger more structurally sound bone. (biomedcentral.com)
