Inguinal triangle
From Wikipedia, the free encyclopedia
Inguinal triangle is not labeled, but can be seen at center left, by tracing out the margins of the three surrounding structures:
inferior epigastric vessels: Run from upper left to center.
inguinal ligament: Runs from upper left to bottom right.
rectus abdominis muscle: Runs from upper left to bottom left, labeled rectus at upper left.
Inguinal triangle is not labeled, but region can be inferred, albeit less clearly than with the diagram above:
inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center.
inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom.
rectus abdominis muscle: runs from upper left to bottom left.
In human anatomy, the inguinal triangle (also known by the eponym Hesselbach's triangle), is a region defined by the the following structures:
- rectus abdominis muscle (medially)
- inguinal ligament (inferiorly)
- inferior epigastric vessels (superior and laterally).
It is the region in which direct inguinal hernias protrude through the abdominal wall.
