uterus[u´ter-us] (pl. u´teri) (L.)
The upper part of the uterus, or fundus uteri, is broad and flattened; the middle part (body), or corpus uteri, is large and open; and the lower part, or cervix uteri, is narrow and tubular and opens downward into the vagina. Two fallopian tubes enter the uterus at the upper end, one on each side. The walls of the uterus are composed of muscle, and its lining is mucous membrane. The muscular substance of the uterus is called the myometrium, and the inner lining is called the endometrium. Between puberty and menopause, the lining goes through a monthly cycle of growth and discharge, known as the menstrual cycle. menstruation is the time in the cycle when the tissue prepared by the uterus for a possible embryo or fertilized egg is unused and passes out through the vagina.
The menstrual cycle is interrupted by pregnancy when a mature ovum is fertilized by a spermatozoon. Fertilization usually takes place in the fallopian tube; the fertilized ovum continues moving along the tube and comes to rest in the uterus, where it implants in the endometrium. The endometrium then serves to anchor the placenta, which filters nutrients from the mother's blood into the blood of the growing fetus. (See also reproduction and female reproductive organs.)

uterus/uter·us/ (u´ter-us) pl. u´teri [L.] the hollow muscular organ in female mammals in which the blastocyst normally becomes embedded and in which the developing embryo and fetus is nourished. Its cavity opens into the vagina below and into a uterine tube on either side.

uterus(ut'e-rus) [L. uterus, womb]
The uterus is a muscular, hollow, pear-shaped organ situated in the midpelvis between the sacrum and the pubic symphysis. Before child-bearing, it is about 3 in. (7.5 cm) long, 2 in. (5 cm) wide, and 1 in. ( 2.5 cm) thick. Its upper surface is covered by the perimetrium, and it is supported by the pelvic diaphragm supplemented by the two broad ligaments, two round ligaments, and two uterosacral ligaments. It is usually tilted forward over the top of the urinary bladder. The upper portion of the uterus, between the openings of the fallopian tubes, is the fundus; the large central portion is the body; and the narrow lower end is the cervix, which projects into the vagina. The cavity of the uterus is widest in the fundus. The canal of the cervix is narrow, opens into the uterine cavity at the internal os, and into the vagina at the external os.
The wall of the uterus consists of the outer perimetrium, middle myometrium, and inner endometrium. The uterine and ovarian arteries supply blood to the uterus.
Anteflexion: The uterus bends forward. Anteversion: The fundus is displaced forward toward the pubis, while the cervix is tilted up toward the sacrum. Retroflexion: The uterus bends backward at the junction of the body and the cervix. Retroversion: The uterus inclines backward with retention of the normal curve; this position is the opposite of anteversion.See: hysterectomy; pregnancy

uterusThe female organ in which the fetus grows and is nourished until birth. The uterus is a hollow, muscular organ, about 8 cm long in the non-pregnant state, situated at the upper end of the VAGINA and lying behind and above the URINARY BLADDER and in front of the RECTUM. It is suspended by LIGAMENTS from the walls of the pelvis. The lining of the uterus is called the endometrium. Under the influence of hormones from the ovaries this thickens progressively until shed during menstruation. In pregnancy, the uterus expands considerably with the growth of the fetus until it rises almost to the top of the abdominal cavity.
uterusthe enlarged posterior portion of the OVIDUCT in which the embryo implants and develops in VIVIPAROUS (1) species. The human uterus is also called the womb.
Patient discussion about uterus
Q. Is it safe to have sex with a woman with cancer of the uterus? My 45-years old wife was told she have cancer in the uterus, and will have an operation soon. Meanwhile, should we use a condom during sex? Can the tumor pass from her to me (like AIDS or HPV)?
but if your wife would undergo an operation, maybe you need to be off-of-that-sex 1-2 days prior to operation day, just to make sure there's no super infection that will bother the operation plan.
