What is the rear longitudinal ligament?
The rear longitudinal liga is a long and dense ligament in the spine. It runs from the top of the spine to just above the hip and passes through the back vertebra. Its main function is to prevent injury by limiting the amount of flexion - or forward - the back is able to achieve and help protect the spinal cord. The rear longitudinal ligament consists of a dense group of smooth ligament fibers and contains several layers, depending on whether it is inside or between vertebrae. This liga is in something known as the vertebral channel, which is also called the backbone channel. The spinal channel is the space inside the bones, through which the spinal cord travels. It is a long ligament that leads from the upper part of the spine, coming from the vertebra known as the axis, except to the bottom of the spine, to the part of the body called the cross. It is wider and stronger, increasingly on the spine you go, specifically in the thoracic area of the spine. In the body of each of the vertebra, the ligament is thin; It is wider between the vertebrae, known as the disk space.
The function of the bonds is usually stabilization of the surrounding joints and bones. While the rear longitudinal ligament provides stability in the spine, it also affects the protection of the spinal cord. The spinal cord is essential for the movement and function of the whole body, so this special protection is important. In addition to protection, the rear longitudinal ligament also helps reduce the amount of flexion at the back. This prevents bending the back forward behind the safe range.
Along with the rear ligament, the back also has a front longitudinal ligament. It runs down the front of the spine. It is different from the shape of the rear longitudinal ligament, because it is not so wide in the gap between the vertebrae. It is located on the opposite side of the spine and helps reduce the back extension, which includes a person bending backwards to supplement the bend connected to the bending.
