The supravesical fossa is a depression upon the inner (i.e. peritoneal) surface of the anterior abdominal wall superior to the bladder
formed by a reflection of the
peritoneum
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesotheli ...
onto the superior surface of the bladder.
It is bounded by the
medial umbilical fold
The medial umbilical fold is an elevation of the peritoneum (on either side of the body) lining the inner surface of the lower anterior abdominal wall formed by the underlying medial umbilical ligament (the obliterated distal portion of the umbili ...
and
median umbilical fold
In human anatomy, the median umbilical ligament is an unpaired midline ligamentous structure upon the lower inner surface of the anterior abdominal wall. It is covered by the median umbilical fold.
The median umbilical ligament represents the re ...

The level of the supravesicular fossa varies according to the fullness of the bladder as the peritoneum is not firmly attached to the upper surface of the bladder (the only region where this is the case).

In anatomy, the abdominal wall represents the boundaries of the abdominal cavity. The abdominal wall is split into the anterolateral and posterior walls.
There is a common set of layers covering and forming all the walls: the deepest being the vi ...
