Human back

The back (Latin dorsum, Old High German hrukki, Sanskrit krúñcati ' curved ') is the back side of the body of animals and humans, that extends from the bottom of the neck to the area of the loin and the tip of the coccyx.

The back is the rear portions of the ribs from the spinal column and formed, the above and located next to these soft parts; colloquially the two shoulder blades resting the shoulder girdle are often to be counted. In the midline of the back extends a substantial groove in the backbone with the spinous processes will be visible on both sides bounded by a muscular bead. These long extensor muscles of the back are part of the local constant back muscles, which is divided into five sub-systems of muscle groups of different directions, which are used in combination the upright, upright holding, stretching, lateral bending and twisting of the spine ( and are collectively referred to as the musculus erector spinae ). In addition, the back muscles are more muscles involved especially when lifting and lowering of the ribs and in the movements of upper arm, shoulder and head.

Widespread deformation of the back are bending and imbalances that are often accompanied by tension from shoulders or neck. Often they are a consequence of unilateral posture, especially during prolonged sitting or screen work, or even in unfavorable sleeping positions. But the hunchback and the earlier frequent hump come before.
