lat·er·al in·gui·nal fos·sa[TA]
a depression on the peritoneal surface of the anterior abdominal wall lateral to the ridge formed by the inferior epigastric artery; it corresponds to the position of the deep inguinal ring, and is the site of an indirect inguinal hernia.
Synonym(s): fossa inguinalis lateralis [TA]
One of two vertical valleys in the peritoneum along each side of the anterior abdominal wall. The medial inguinal fossa is the depression between the medial and lateral umbilical folds; direct inguinal hernias typically protrude through the abdominal wall in the lower end of this fossa. The lateral inguinal fossa is the depression lateral to the lateral umbilical fold; the lower end of this fossa becomes the deep inguinal ring, the internal end of the inguinal canal.
