The lower part of the trunk is the pelvis. This consists of the two hip bones (ossa coxae) and contains the internal pelvic organs. The abdomen is located between the rib cage (height of the tip of the sternum) and the pelvis (up to the inguinal ligament). Within the abdomen is a fluid-filled cavity - the abdominal cavity or abdomen. The diaphragm forms the upper limit of the abdominal cavity. Below it it is bounded by the hip bone and the pelvic floor. The back extends from the loin or coccyx to the lower part of the neck. This includes the spine, the rear parts of the ribs and soft tissues such as connective tissue and back muscles. The thorax is formed by the thoracic spine, the sternum and the ribs. The respiratory musculature attaches itself to the outside and inside of the rib cage.
