What does the Superior Epigastric Artery supply?

The Superior Epigastric Artery primarily provides blood supply to the rectus abdominis muscle. This artery is a continuation of the internal thoracic artery and travels downwards, supplying the upper portion of the anterior abdominal wall. The rectus abdominis, a key muscle responsible for flexing the lumbar spine, relies on this arterial supply for oxygenation and nutrient delivery, making the connection between the artery and the muscle crucial for its functions during various physical activities, such as lifting or twisting. This, in turn, plays a significant role in core stability and movements involving the trunk. Understanding this specific supply can enhance comprehension of abdominal vascularization and muscle function within the human anatomy context.
