THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The lesser pelvis contains the pelvic colon, rectum, bladder, and some of the sex organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis.

Detailed explanation-2: -The internal genitalia are those organs that are within the true pelvis. These include the vagina, uterus, cervix, uterine tubes (oviducts or fallopian tubes), and ovaries. The external genitalia lie outside the true pelvis.

Detailed explanation-3: -The pelvic 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.

Detailed explanation-4: -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.
