Osteoporosis is a disease characterized by loss of bone mass and changes in tissue microarchitecture of the bone, which compromise bone quality. Fatigue damage in bone manifests itself in the form of microcracks. Such cracks have been implicated in physiological phenomena, including stress fractures (Burr et al.
What does cortical bone mean?
Cortical bone is the dense outer surface of bone that forms a protective layer around the internal cavity. This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion.
Is micro damage good or bad?
The intertwined mechanical and biological effects of microdamage on bone tissue are complex. In one sense, its presence potentially weakens the bone and reduces fracture resistance. Contrastingly, microdamage can be an effective way of dissipating energy in composite materials.
What is osteoporosis?
Osteoporosis means that you have less bone mass and strength. The disease often develops without any symptoms or pain, and it is usually not discovered until the weakened bones cause painful fractures. Most of these are fractures of the hip, wrist and spine.
Where is cortical bone found?
long bones
Cortical bone tissue is mostly located in the outer layer of the long bones forming the shaft and inner part of the trabecular bone at the proximal and distal ends of the bone tissue. Moreover, it constitutes about 80% of the total mass of the skeleton in our body.
How is Microplastic harmful?
Microplastics can carry a range of contaminants such as trace metals and some potentially harmful organic chemicals. These chemicals can leach from the plastic surface once in the body, increasing the potential for toxic effects. Microplastics can have carcinogenic properties, meaning they potentially cause cancer.
Do microplastics leave your body?
Microplastics have already been discovered in human stool, so we know they pass through our bodies. Similarly, plastic components such as bisphenol A, aka BPA, have been discovered in urine—but also in samples of human tissue including lungs, meaning they linger in our bodies, not just pass through them.
What is cortical fracture?
Each cortical bone fracture begins as a sub-microscopic crack that enlarges under mechanical load, for example, that imposed by a fall. In these conditions, a crack will enlarge explosively unless the cortical bone is intrinsically tough (the opposite of brittle).
What is cortical?
Definition of cortical 1 : of, relating to, or consisting of cortex. 2 : involving or resulting from the action or condition of the cerebral cortex. Other Words from cortical Example Sentences Learn More About cortical.
