(Science: anatomy) The hollow muscular organ in female mammals in which the fertilized ovum normally becomes embedded and in which the developing embryo and foetus is nourished. In the nongravid human, it is a pear shaped structure, about 3 inches in length, consisting of a body, fundus, isthmus and cervix. Its cavity opens into the vagina below and into the uterine tube on either side at the cornu. It is supported by direct attachment to the vagina and by indirect attachment to various other nearby pelvic structures.
