Epigastrium
Epigastrium
The Epigastrium (pronounced: epi-gas-tri-um) is a region of the human body located in the upper central region of the abdomen. It is one of the nine regions of the abdomen that was defined by anatomists and physicians in the 19th century.
Etymology
The term "Epigastrium" is derived from the Greek words "epi", meaning "upon", and "gaster", meaning "stomach". Thus, the term literally translates to "upon the stomach".
Anatomy
The Epigastrium is located between the subcostal plane and the transpyloric plane. It is superior to the umbilical region and is flanked by the right and left hypochondriac regions. The Epigastrium covers part of the stomach, the liver, the pancreas, and the duodenum.
