In the profile or vertical section the body may be divided into three horizontal sections, the upper containing the cage of ribs, the central containing the abdominal mass, located between the false ribs and the crest of the pelvis, and the lower containing the pelvis, the lower portion of the abdomen and the extremity of the back.

The upper and lower masses are remarkable for their bony character. The upper, like a cage made of the ribs, the sternum, the clavicles and the scapula, all supported by the spine, encloses the vital organs. The muscles that clothe this form are greatly affected by this bony cage in the production of the planes. The only bony form in the central mass is the column of vertebrae in the small of the back. In the lower mass the bones are heavy and deep-seated instead of external, only coming to the surface at crest of the pelvis, the coccyx, and the head of the femur or hip bone; aside from the crest of the pelvis and head of the femur, which form the two bony points in the buttresslike form on each side, the bones affect the external form less than above. The muscles producing the external planes come from a deeper origin in consequence, and are less affected externally by the bones within.
