The musculus sacrolumbalis, commonly known as the erector spinae muscle, is a group of deep muscles located in the back. Specifically found in the lumbar region, these muscles span the area between the sacrum and the lower thoracic vertebrae. As part of the deep layer of the intrinsic back muscles, the musculus sacrolumbalis comprises three individual muscles: the iliocostalis, longissimus, and spinalis. Although each muscle has slightly different attachment points and functions, they work collectively to support and stabilize the spine, aiding in various movements and maintaining upright posture.
The musculus sacrolumbalis assists in extending the spine, allowing individuals to lean backward, arch their back, or stand upright. Additionally, these muscles aid in lateral bending and rotation of the spine. They play a crucial role in the overall movement and stability of the lumbar region.
Injury or strain to the musculus sacrolumbalis can result in lower back pain, limited motion, and discomfort. To prevent or address such issues, stretching and strengthening exercises targeting these muscles may be recommended. Physical therapists and healthcare professionals often employ techniques to rehabilitate and optimize the function of the musculus sacrolumbalis, especially in cases of back pain or postural problems.

The word "musculus sacrolumbalis" is a Latin term referring to a specific muscle in the human body. Here is the breakdown of its etymology:
1. Musculus: This is the Latin word for "muscle". It comes from the Latin term "musculus" meaning "little mouse" because the ancient Romans thought that certain muscles looked like small mice running under the skin when they contracted.
2. Sacrolumbalis: This term is a combination of two Latin words:
- Sacro: Derived from the Latin word "sacrum" which means "sacred" or "sacrum" referring to the triangular bone at the base of the spine (also known as the sacrum) which joins the hip bones.
- Lumbalis: Derived from the Latin word "lumbus" which means "loin" or "lower back".
