The abdominal cavity and pelvic cavity are surrounded by muscles of the abdominal wall. The pelvis and the pelvic floor muscles seal the abdominal and pelvic cavity in caudal direction; in cranial direction, the abdominal cavity is bordered by the diaphragm. Dorsally, there are the posterior abdominal muscles, the back muscles, and the lumbar spine.
