Definition

Noun: 1. A slight depression in the midline of the abdomen just below the sternum (breastbone): This is a specific anatomical landmark on the surface of the body. It is the surface marking of a region where a cluster of nerves, the celiac plexus (often called the solar plexus), is located internally. A blow to this area can affect these nerves.

Usage Notes

• The epigastric fossa is a precise anatomical term used in medicine and biology. It is not used in everyday conversation.
• It is synonymous with the common term pit of the stomach.
• Its location is described as being in the epigastrium, which is the upper central region of the abdomen.

Examples

• Noun:
  • During the physical examination, the doctor palpated the epigastric fossa for any tenderness.
