The graticule shows the latitude and longitude of points on the surface. In this example meridians are spaced at 6Â° intervals and parallels at 4Â° intervals. In geography, latitude is a geographic coordinate that specifies the northâsouth position of a point on the Earth's surface.
In the lower back, the damaged disc can cause pain to travel to the hips, buttocks, legs and feet. In the cervical spine, pain can radiate from the neck, down the arm and to the fingers. Approximately 90 percent of bulging discs occur in the lower back, or lumbar area, of the spine.
Injury to the disc may occur when neck motion puts too much pressure on the disc. One of the most painful injuries that can occur is a herniated disc. In this injury, the tear in the surface of the disk is so bad that part of the inside of the disk squeezes out. A tear or rupture can occur anywhere around the disc.
