The term "arteria jejunalis" refers to the artery that supplies the jejunum, which is the second part of the small intestine. The IPA phonetic transcription for this word would be [ɑrˈtɪriə jeˈdʒunəlɪs]. The first part of the word "arteria" is spelled with a "t" instead of a "d," which may cause confusion for some as it sounds similar to "artery." The second part of the word "jejunalis" is spelled with a "j" instead of a "g," which can also be confusing due to the similarity in sound between the two letters.
Arteria jejunalis, also known as the jejunum artery, is a medical term used to describe one of the branches of the superior mesenteric artery. It is an important blood vessel that supplies oxygenated blood to the jejunum, which is the second part of the small intestine. In the human body, the superior mesenteric artery arises from the abdominal aorta and gives off several branches, one of which is the jejunal artery.
The arteria jejunalis runs along the mesentery, a fold of tissue that supports and suspends the intestines in the abdominal cavity. It travels parallel to the jejunum, providing a rich blood supply to this portion of the small intestine. This arterial blood supply is crucial for supplying oxygen and nutrients to the cells within the jejunum, facilitating proper digestion and absorption of nutrients.
The arteria jejunalis typically gives off numerous smaller branches, which form an intricate network of blood vessels within the jejunum. These branches help to ensure adequate perfusion and oxygenation of the intestinal wall. Additionally, the jejunal artery anastomoses or connects with neighboring arteries, such as the ileal arteries and the pancreaticoduodenal arteries.
Understanding the anatomy and function of the arteria jejunalis is important in medical disciplines such as surgery and radiology. Surgeons must be knowledgeable about the blood supply to the jejunum when performing procedures involving this part of the small intestine. Radiologists may also evaluate the blood flow in the arteria jejunalis and its branches using imaging techniques to diagnose conditions such as intestinal ischemia or malabsorption disorders.

The word "arteria jejunalis" consists of two roots: "arteria" and "jejunalis".
1. Arteria: The word "arteria" comes from the Latin term "arteria" which means "windpipe, artery". It was derived from the Greek word "artēria", meaning "windpipe" or "airpipe". In ancient anatomy, this term was used to describe the blood vessels that carry oxygenated blood away from the heart, distinguishing them from the veins.
2. Jejunalis: The term "jejunalis" comes from the Latin word "jejunus" which translates to "empty, fasting". In anatomy, it specifically refers to the jejunum, which is the middle portion of the small intestine. This term was likely used to describe an artery that supplies blood to the jejunum.
