Psoas major
is a long fusiform muscle located on the side of the lumbar region of the vertebral column and brim of the lesser pelvis. It joins the iliacus muscle to form the iliopsoas.
Between the peritoneum and the muscular wall there is an extraperitoneal layer of fat and deep fascia called the ________
transversalis fascia.
The transverse fascia (or transversalis fascia) is a thin aponeurotic membrane which lies between the inner surface of the transverse abdominal muscle and the parietal peritoneum.
It forms part of the general layer of fascia lining the abdominal parietes, and is directly continuous with the iliac fascia, internal spermatic, and pelvic fasciae.
In the inguinal region, the transverse fascia is thick and dense in structure and is joined by fibers from the aponeurosis of the transverse abdominal. It becomes thin as it ascends to the diaphragm and blends with the fascia covering the under surface of this muscle.
The peritoneum /ˌpɛrᵻtəˈniːəm/ is the serous membrane that forms 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 mesothelium supported by a thin layer of connective tissue.
