What is the spine?
spine, alternately known as a vertebral column or spine, is a structure that closes and protects the spinal cord, a bundle of nerves that transmits signals from the brain to the rest of the body. It consists of a pile of bones - 33 vertebrae, cross and koccyx - and intervertebral discs separating bones. The spine is divided into regions known as uterine, thoracic and lumbar, while the pelvic area containing the cross and coccyx was considered a separate entity. One of them is the place where the spine curve changes: the cervical spine curves, the thoracic curves in and the lumbar curves again out. Another is the presence of the rib cage; The hip area is a place where the ribs are attached to individual turnover. The third characteristic is whether the vertebrae can move due to each other. Cross and Coccyx, for example, are formed by several fused vertebrae, which combine that they lack intervertebral discs that absorb shock, hold the vertebrae together and allow the turnover to move with each other.
in the cervical spine, identified as C1-C7, there are seven vertebrae, five of which are movable. The upper two, C1 and C2 are largely responsible for head support - C1 is known as Atlas Bone as a nod to a character in Greek mythology that carried the weight of the world on its shoulders. Player vertebrae, which are mainly in the throat, are the smallest individual vertebral bones. To this part of the vertebral column, including a large trapezoid muscle, a muscle that shrugs.
12 thoracic vertebrae is referred to as T1-T12 and are located at the top of the back. Their mosnos characteristic is the presence of so -called bone aspects, which are surfaces on each vertebra where the ribs are joined. In relation to the uterine vertebra, the thoracic vertebrae are slightly larger and absorb a slightly greater weight. It also serves as a place of attachment for more muscles than cervical vertebrae, including trapezoids, but also rhombic and latissimUS dorsi, the largest of the rear muscles.
While there are only five vertebrae in the lumbar spine, it is the largest, absorbing the high weight of the torso above them. They start where the rib cage ends and as such has no freight aspects. Easily vulnerable to injuries, lumbar vertebrae are surrounded only by soft tissues and are exposed not only to compression forces, but also by the strength of the body from several different directions. This is one of the reasons why it is recommended to strengthen the basic muscles surrounding the lumbar region, especially in individuals who perform frequently/or the movements of heavy lifting.
Finally, the base of the vertebral column, where there are cross and coccyx. It consists of five molten vertebrae and is located under the lumbar spine between two hipbones and holds them together. Coccyx, alternately known as the tail bone, consists of four fused vertebrae, which, like the ones that are doing, grow as the spine descends. Coccyx does not serve many other functions than act as a place of attachmentFor many pelvic floor muscles, even if it allows people to cope in sitting while leaning backwards.
