TRIGONUM LUMBALE Meaning and
Definition
-
The term "trigonum lumbale" refers to a specific anatomical region located in the lower back, more specifically, in the lumbar (lower) region of the vertebral column. It is derived from the Latin words "trigonum," which means "triangle," and "lumbale," which refers to the lumbar region.
The trigonum lumbale is a triangular-shaped area that lies between the posterior abdominal wall and the fascia of the quadratus lumborum muscle. It is bordered by several anatomical structures, including the 12th rib superiorly, the internal oblique muscle laterally, and the erector spinae muscle medially.
Within the trigonum lumbale region, various anatomical features can be found. For example, important structures such as the kidney, associated blood vessels (including the renal artery and vein), and the ureter (the tube that carries urine from the kidney to the bladder) traverse through this area.
The trigonum lumbale plays a significant role in supporting and stabilizing the lower back and the surrounding structures. It is also involved in the functioning of the urinary system, as it houses the kidney and the ureter, facilitating the transport of urine. This region is of particular importance in medical fields such as anatomy, surgery, and urology, where a thorough understanding of its structure and function is essential for accurate diagnoses and effective treatment of various conditions that may affect the lower back or urinary system.
