MUSCULUS SACROSPINALIS Meaning and Definition

1. Musculus sacrospinalis, also known as the erector spinae or spinal erectors, is a group of muscles located on either side of the vertebral column in the human body. It is an important muscle group involved in maintaining posture, providing stability to the spine, and allowing for various movements of the back.

   The musculus sacrospinalis is divided into three distinct sections: the iliocostalis, longissimus, and spinalis muscles. The iliocostalis muscle is further divided into three parts: the iliocostalis cervicis, iliocostalis thoracis, and iliocostalis lumborum. Similarly, the longissimus muscle is divided into thoracis, cervicis, and capitis parts, while the spinalis muscle includes the thoracis and cervicis sections.

   Collectively, these muscles play a crucial role in extending and rotating the spine. They also help to laterally flex the spine and assist in maintaining an upright posture. Additionally, the musculus sacrospinalis is involved in movements such as bending forward (flexion), backward (extension), and sideways (lateral flexion).

   These muscles receive their blood supply from branches of the posterior intercostal arteries and the lumbar arteries and are innervated by the posterior rami of spinal nerves. They work in coordination with other muscles of the back, as well as the abdominal muscles, to provide stability, support, and controlled movement of the spine.

   Overall, the musculus sacrospinalis is a complex muscle group responsible for various movements and functions of the back, making it an essential component of the musculoskeletal system.

2. M. erector spinae; origin, from dorsal surface of sacrum, spines of lumbar vertebrae, and crest of ilium; then divides into iliocostalis and longisimus dorsi muscles; action, extends spinal column; nerve supply, posterior branches of spinal nerves.

Etymology of MUSCULUS SACROSPINALIS

The term musculus sacrospinalis comes from two Latin words: musculus meaning muscle and sacrospinalis, which is a combination of two words - sacro meaning sacrum and spinalis meaning spinal. In Latin, sacrum refers to the triangular bone at the base of the spine, and spinalis relates to the spine or the backbone. Therefore, musculus sacrospinalis is a Latin term that can be translated as the muscle of the sacrum and spine or the muscle of the sacrum and spinal column.
