b. Uterus. The uterus is the site where all but the first few days of embryo
development takes place. After eight weeks of embryonic development, it is known as
(1) Main subdivisions. The uterus is shaped like a pear, with the stem
(cervix) facing downward and toward the rear. The fundus is the portion of the uterus
above the openings of the uterine tubes. The main part, or body, is the portion between
the cervix and the fundus. The uterus usually leans forward with the body slightly
curved as it passes over the top of the urinary bladder. The cervix opens into the upper
end of the vagina.
