SACROSPINALIS Meaning and
Definition
-
The term "sacrospinalis" is a noun that refers to a group of muscles located in the back region of the human body. More specifically, it is a large muscle group situated on either side of the spine. The sacrospinalis is sometimes referred to as the erector spinae or the paraspinal muscles.
The sacrospinalis muscles play a crucial role in maintaining posture and providing stability to the spine. They are responsible for extending and straightening the back, as well as assisting in lateral movements, rotation, and flexion of the trunk. These muscles are complex and consist of three main muscles: the iliocostalis, longissimus, and spinalis.
The iliocostalis muscle runs along the side of the spine and is divided into three sections: the iliocostalis cervicis, thoracis, and lumborum. The longissimus muscle, also divided into three sections (longissimus capitis, longissimus cervicis, longissimus thoracis), is located medial to the iliocostalis. Lastly, the spinalis muscle runs closest to the spine and is further divided into three subsections: spinalis capitis, spinalis cervicis, and spinalis thoracis.
The sacrospinalis muscles are heavily involved in numerous daily activities that require back movement and stability, such as lifting, standing, and sitting. However, like all muscle groups, they are also susceptible to strain and injury, commonly associated with poor posture, repetitive movements, or excessive stress on the back.

Etymology of SACROSPINALIS
The word "sacrospinalis" is derived from Latin, combining two roots: "sacro-" and "spinalis".
1. "Sacro-" refers to the sacrum, the triangular bone at the base of the spine that is connected to the pelvis. It comes from the Latin word "sacrum", meaning "sacred" or "holy". The sacrum was considered sacred because it was believed to be the seat of the soul or life force.
2. "Spinalis" is derived from the Latin word "spina", which means "thorn" or "spine". It refers to the spine or vertebral column.
Therefore, "sacrospinalis" is a composite term combining "sacro-" (related to the sacrum) and "spinalis" (related to the spine).
