What is Longissimus?

Longissimus muscle with its three subdivizes is part of the muscle group Erector Spinae at the back. Alternatively known as Satrospinalis, the muscles Erector Spinae runs parallel to the spine from the skull base to the base of the spine. Longissimus Subdivize is laterally to semispinalis, other SPINAE muscle, Longissimus Toraracis, Longissimus cervicis and Longissimus Capitis.

Longissimus capitis is the highest muscles Longissimus. It comes from attaching tendons on the transverse processes of the first four or five thoracic vertebrae, as well as the processes of the lower three or four cervical vertebrae. From there it runs up the neck on both sides of the spine and inserts into the mastoid process, the bony meaning on the underside of the temporal bone on each side of the skull. The task of this muscle is to bend the head and neck to the side to which the contractual muscles placed.

Next down in the vertebral column is Longissimus cervicis, the second largest group Longissimus. Found just below the chapter and slightly medially, afterIt also looks at the transverse processes of the first four or five thoracic vertebrae, which appear from long tendons. Cervicis, however, is inserted through tendons into the second to sixth cervix. Its action is to bend the head and neck to the side and also help in extending the upper spine.

The largest of Longissimus's muscles is Longissimus Thoracis, which covers almost the entire length of the back. It shares its origin with IlioCostalis lumborum, another muscle of satospinalis, which results from the transverse processes of the lumbar vertebrae. From there, the muscles stretch to the thoracic spine, where it attaches to all thoracic vertebral and the lower nine or ten ribs.longissimus thoracis works bilaterally or on both sides to extend the entire vertebral column.

together with muscle groups IlioCostalis and spinalis and their accompanying tendons is the predominant function of the Longissimus group to extend the spine or pull the fuselage back from the positionsy forward. Because most of the extensions occur in the Lumbo-Toracic area in the spine or in the middle to the lower back, these muscles in this area are larger together, shorter and narrower as they approach the top of the spine. The Erektor Spinae muscle group can become quite close between individuals sitting across the table all day; This effect can be fought by incorporating the lower back and also a broadcast core strengthening into a regular exercise program.
