THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The pelvic cavity is a bowl-like structure that sits below the abdominal cavity. The true pelvis, or lesser pelvis, lies below the pelvic brim (Figure 1).

Detailed explanation-2: -The hip is the area on each side of the pelvis. The pelvis bone is made up of 3 sections: Ilium. The broad, flaring portion of the pelvis.

Detailed explanation-3: -These muscles relax to allow micturition and defecation. During activities such as coughing or lifting heavy objects, the pelvic floor helps support the maintenance of intra-abdominal pressure. The pelvic floor consists of the urogenital triangle, the urogenital diaphragm, and the pelvic diaphragm.

Detailed explanation-4: -The pelvic outlet also called the inferior pelvic aperture, defines the lower margin of the lesser (true) pelvis. The pelvic cavity (the true pelvis) predominantly contains the urinary bladder, the colon, and the internal reproductive organs. This space is enclosed between the pelvic inlet and the pelvic outlet.
