The term "arteria epigastrica superior" is a mouthful, but its spelling can be broken down using the International Phonetic Alphabet (IPA). The first syllable "ar-" is pronounced like the letter "R" with a schwa sound "ə" in front of it. "Teria" is pronounced "tɛria." "Epi" is pronounced "ɛpi," and "gastrica" is pronounced "gæstrica." Lastly, "superior" is pronounced "supɪriər." So, with this breakdown, we can easily see how the word is spelled and pronounce it correctly.
The arteria epigastrica superior, also known as the superior epigastric artery, is a small blood vessel that is responsible for supplying oxygenated blood to the upper abdomen. It is one of the two terminal branches of the internal thoracic artery (ITA), the other being the musculophrenic artery.
Originating from the ITA, which itself is a branch of the subclavian artery, the arteria epigastrica superior courses downwards towards the abdominal wall. It runs parallel and next to the sternum, before eventually dividing into multiple branches that supply the surrounding tissues.
The arteria epigastrica superior is crucial in supplying blood to the upper abdominal muscles, the rectus abdominis muscle, and the overlying skin and connective tissues. These structures rely on a constant supply of oxygen and nutrients to maintain their normal function.
In medical procedures such as coronary artery bypass grafting or breast reconstruction surgery, the arteria epigastrica superior can be an important artery for grafts or flaps due to its close proximity to the chest wall. Therefore, preserving its integrity during surgery is crucial to prevent complications and ensure optimal blood supply to the relevant areas.
Overall, the arteria epigastrica superior plays a significant role in the vascular supply of the upper abdomen, providing vital nourishment to various muscles and tissues in this region.
Origin, the inner terminal branch of mammaria interna; distribution, abdominal muscles and integument, falciform ligament; anastomoses, epigastrica inferior and hepatica.
