The term "plexus haemorrhoidalis superior" refers to a specific anatomical structure in the human body, primarily found in the rectum and anus. This complex network of blood vessels, often referred to as the superior hemorrhoidal plexus or superior rectal plexus, is an integral part of the circulatory system in this region.
The plexus haemorrhoidalis superior is responsible for supplying blood to the upper part of the rectum and surrounding tissues. It is formed by the convergence of several different blood vessels, primarily the superior rectal artery and its tributaries. This intricate network of blood vessels is located within the submucosa layer of the rectum.
The plexus haemorrhoidalis superior plays a crucial role in maintaining the health and functionality of the rectal and anal area. It ensures an adequate blood supply, which is essential for the nourishment and oxygenation of the tissues. Furthermore, it helps to regulate blood flow and pressure, preventing congestion or pooling of blood.
Issues related to the plexus haemorrhoidalis superior can lead to various medical conditions, such as hemorrhoids. Hemorrhoids occur when the blood vessels in this plexus become swollen or inflamed, resulting in discomfort, pain, and sometimes bleeding.
Understanding the anatomy and function of the plexus haemorrhoidalis superior is important for medical professionals involved in the diagnosis and treatment of conditions affecting the rectal and anal area.
Superior hemorrhoidal p., a sympathetic p. on the artery of the same name, derived from the inferior mesenteric and distributed to the rectum.
