ARTERIA SIGMOIDEA Meaning and
Definition
-
Arteria sigmoidea refers to the sigmoid artery, a major blood vessel that supplies oxygenated blood to the sigmoid colon and parts of the rectum. It is a branch of the inferior mesenteric artery, which is responsible for providing blood to the large intestine.
The sigmoid artery typically arises from the left side of the inferior mesenteric artery, immediately above the bifurcation of the aorta. It traverses the sigmoid mesocolon and follows a course parallel to the sigmoid colon. As it travels, it gives off branches that form an intricate network of blood vessels, ensuring an adequate blood supply to the sigmoid colon and rectum.
The artery sigmoidea plays a crucial role in maintaining the health and proper functioning of the sigmoid colon and rectum. It provides the necessary oxygen and nutrients to sustain the cells and tissues in these regions. Additionally, the sigmoid artery is responsible for carrying away waste products and carbon dioxide for elimination from the body.
Disruptions in the blood flow through the arteria sigmoidea can have severe consequences. Conditions like ischemic colitis or bowel infarction may occur when the artery becomes blocked or experiences reduced blood flow. These conditions can lead to tissue damage and potentially life-threatening complications, highlighting the importance of a healthy and well-functioning arteria sigmoidea.

Etymology of ARTERIA SIGMOIDEA
The word "arteria sigmoidea" has its etymology rooted in Latin and Greek.
The term "arteria" comes from the Latin word "arteria", which means "airpipe" or "artery". In ancient Greek, "arteria" referred to the windpipe, but in the context of anatomy, it started to be used to describe the blood vessels.
The word "sigmoidea" is derived from the Greek term "sigma" (Σ), which represents the letter "S" in the Greek alphabet. This letter is named after its resemblance to the Greek letter sigma. In anatomy, "sigmoidea" is used to describe structures that have a shape resembling the letter "S".
Therefore, "arteria sigmoidea" describes an artery with a curved or S-shaped structure.
