New Study Maps Abdominal Aorta and Pelvic Nerves in Detail
A team of researchers from the Medical University of Graz, the University of Graz, and the Technical University of Graz has published a detailed study on the abdominal aorta and its branches. The study provides a comprehensive overview of the blood vessel and nerve structures in the pelvic region, which are crucial for various bodily functions.
The abdominal aorta, the largest artery in the human body, originates from the thoracic aorta and supplies oxygenated blood to various organs and limbs. It branches into several vital vessels, including the superior mesenteric artery, which nourishes most of the small intestine and the first half of the large intestine. The inferior mesenteric artery handles the remaining large intestine's blood supply.
The abdominal aorta also gives rise to the common iliac arteries, which supply blood to the legs. These arteries further branch into the external iliac arteries, which run through the pelvis and supply blood to the pelvic region. The internal pudendal artery, a branch of the internal iliac artery, is responsible for supplying blood to the penis, enabling erections.
The study also delves into the nerve structures of the pelvis. The sacral plexus, a network of nerves originating from the sacral plexus, serves the pelvic area, genitals, buttocks, and parts of the legs and feet. The sciatic nerve, the largest nerve in the human body, also branches from the sacral plexus and runs through the buttocks and down the back of the thigh. Additionally, the testicular arteries, which supply blood to the testes, originate from the abdominal aorta.
The research team also explored the venous system, highlighting the role of veins like the external iliac veins in returning oxygen-depleted blood back to the heart via the inferior vena cava.
This comprehensive study sheds light on the intricate network of blood vessels and nerves in the pelvic region, providing a deeper understanding of the body's cardiovascular system and its functions. The findings could contribute to improved diagnostics and treatments for conditions related to the abdominal aorta and pelvic nerves.
