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 ...
