Back muscles

Back muscles are arranged in several layers, so they are divided into deep and superficial, which, in turn, are arranged in two layers.

By the middle line of the back is a longitudinal groove back (sulcus dorsi). Along it are easily palpable spinous processes by palpation of the cervical VII and all lying below the vertebrae. On either side of the furrow is noticeable relief of back extensor spine.
