Sigmoid arteries

The inferior mesenteric artery and its branches, the sigmoid artery at the bottom right of the picture

The arteriae sigmoideae ("sigmoid arteries") are arteries (arteries) of the abdominal cavity. Usually three Aa go. sigmoideae as the 2nd to 4th branch from the inferior mesenteric artery (lower intestinal artery ), but two of these arteries can also start off from the mesenteric artery in a common starting section and only split shortly afterwards. Its job is to supply parts of the large intestine , mainly the sigmoid colon .
