The spelling of the medical term "arteria sacralis lateralis" can be tricky to decipher. The word is composed of four distinct parts, each with their own pronunciation. "Arteria" is pronounced /ɑrˈtɪəriə/, while "sacralis" is pronounced /sækˈreɪlɪs/. "Lateralis" is pronounced /lætəˈrælɪs/ with a slightly different stress pattern. The final component, "sacralis lateralis," means the artery is located on the side of the sacrum bone. Though it may be difficult to spell and pronounce, this term is essential for medical professionals to use when discussing the human body's arterial system.
The term "arteria sacralis lateralis" refers to one of the main blood vessels located in the human body. Specifically, it is an anatomical structure that can be found in the pelvic region, originating from the common iliac artery.
The "arteria sacralis lateralis" is responsible for supplying oxygenated blood to various structures in the pelvic region, including the sacrum and the nearby areas. It branches off from the common iliac artery, which is a major blood vessel that bifurcates into the internal iliac artery and the external iliac artery. The lateral sacral artery arises directly from the posterior division of the internal iliac artery and usually consists of two branches.
This blood vessel has a crucial role in providing the necessary nutrients and oxygen to the surrounding tissues to maintain their proper function. It assists in the blood supply to the sacrum, which is a triangular bone situated at the bottom of the vertebral column, forming the back of the pelvis. Additionally, the lateral sacral artery contributes to the blood supply of adjacent structures, including the pelvic wall muscles and some of the gluteal muscles.
Understanding the anatomy and function of the "arteria sacralis lateralis" is important for healthcare professionals, particularly surgeons and radiologists, as it can have significant implications for surgical interventions and diagnostic procedures in the pelvic region.
