The transversalis fascia is a layer in the make-up of the posterior inguinal wall. It is the deepest, thinnest, and least important layer in terms of the prevention of herniation. It is a segment of the wider endoabdominal fascia. The true posterior wall of the inguinal canal is formed, in varying degrees, by the muscles or aponeuroses of the internal oblique and transversus abdominis. Plainly, Daedalus was not needed to show surgeons and anatomists how to make a labyrinth out of a rabbit hole!

D006550	Hernia, Femoral	A groin hernia occurring inferior to the inguinal ligament and medial to the FEMORAL VEIN and FEMORAL ARTERY. The femoral hernia sac has a small neck but may enlarge considerably when it enters the subcutaneous tissue of the thigh. It is caused by defects in the ABDOMINAL WALL.

D006552	Hernia, Inguinal	An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.

D000071938	Fasciotomy	Surgical incision on the FASCIA. It is used to decompress compartment pressure (e.g. in COMPARTMENT SYNDROMES; circumferential burns and extremity injuries) or to release contractures (e.g. in DUPUYTREN'S CONTRACTURE).	Fasciectomy
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
