The same human<unk> , front imaged by x-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom) The<unk>  (plural<unk>  or<unk> es) is the lower part of the trunk, between the abdomen and the thighs (sometimes also called<unk>  region), together with its embedded skeleton (sometimes also called bony<unk> , or<unk>  skeleton). The<unk>  region of the trunk includes the bony<unk> , the<unk>  cavity (the space enclosed by the bony<unk> , the<unk>  floor, below the<unk>  cavity, and the perineum, below the<unk>  floor. The<unk>  skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony<unk> , called the<unk>  cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and the rectum, while the<unk>  floor at the base of the cavity assists in supporting the organs of the abdomen. In mammals, the bony<unk>  has a gap in the middle, significantly larger in females than in males. Their young pass through this gap when they are born.
