• \Body wall structure\This structure surrounds the abdominopelvic cavity and has two regional parts: the wall of abdominal proper segment of trunk and the pelvic wall, but excludes the pelvic floor and the thoracic diaphragm.\This structure is comprised of the anterior and posterior abdominal wall.\The posterior abdominal wall consists of the posterior abdominal wall musculature including the quadratus lumborum, psoas major and psoas minor and crus of lumbar part of diaphragm; the lumbar vertebrae bodies and transverse processes; the posterior part of abdominal peritoneum; and the abdominal wall including the transversus abdominus, internal and external oblique muscles posterior to the mid-axillary line. This definition is sometimes referred to as the posterior wall of abdomen proper as it excludes the more superficial layers of muscle and skin of the back: the middle layer of the thoracolumbar fascia (medially attached to the transverse process of the vertebra), and the lateral raphae constitute the posterior boundary of the posterior wall of abdomen and separate it from more caudal structures which are part of the lumbar region of back.\Structure of lumbar intervertebral disc\...

• \An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Joint structure\...
