Intervertebral disk – a structure that separates the vertebrae. It serves to absorb the movements of the vertebrae. Intervertebral disc consists of the so-called pulpal core special jelly mass and envelops the fibrous ring, which consists of fibers. Fibrous ring partially fixed to the adjacent vertebral bodies, and partially – to the adjacent intervertebral ligaments. Some parts of the ring are “free” and there may be some stretching of it. Excess load on the fibrous ring leads to the fact that the nucleus breaks pulpal core break fibrous ring at a greater or lesser extent. This leads to the formation of disk herniation .
This video—presented by the National Heart, Lung, and Blood Institute, part of the National Institutes of Health—discusses the NHLBI's Exome Sequencing Project. Made possible by the American Recovery and Reinvestment Act of 2009, this project provided six awards at five academic institutions to identify genetic connections to heart, lung, and blood diseases. Individual studies will address critical health issues, such as heart attack, stroke, COPD (chronic obstructive pulmonary disease), high blood cholesterol, high blood pressure, overweight and obesity, and others.
