Uterus \U"te*rus\, n. [L.]
-
(Anat.) The organ of a female mammal in which the young are developed previous to birth; the womb.
Note: The uterus is simply an enlargement of the oviduct, and in the lower mammals there is one on each side, but in the higher forms the two become more or less completely united into one. In many male mammals there is a small vesicle, opening into the urinogenital canal, which corresponds to the uterus of the female and is called the male uterus, or [NL.] uterus masculinus.
(Zo["o]l.) A receptacle, or pouch, connected with the oviducts of many invertebrates in which the eggs are retained until they hatch or until the embryos develop more or less. See Illust. of Hermaphrodite in Append.
Douglas Harper's Etymology Dictionary
"female organ of gestation, womb," late 14c., from Latin uterus "womb, belly" (plural uteri), from PIE root *udero- "abdomen, womb, stomach" (cognates: Sanskrit udaram "belly," Greek hystera "womb," Lithuanian vederas "sausage, intestines, stomach, lower abdomen," Old Church Slavonic vedro "bucket, barrel," Russian vedro).

The uterus (from Latin "uterus", plural uteri) or womb is a major female hormone-responsive reproductive sex organ of most mammals, including humans. One end, the cervix, opens into the vagina, while the other is connected to one or both fallopian tubes, (uterine tubes) depending on the species. It is within the uterus that the fetus develops during gestation, usually developing completely in placental mammals such as humans and partially in marsupials such as kangaroos and opossums. Two uteri usually form initially in a female and usually male fetus, and in placental mammals they may partially or completely fuse into a single uterus depending on the species. In many species with two uteri, only one is functional. Humans and other higher primates such as chimpanzees, usually have a single completely fused uterus, although in some individuals the uteri may not have completely fused. Horses, on the other hand, have bipartite uteri. In English, the term uterus is used consistently within the medical and related professions, while the Germanic-derived term womb is more common in everyday usage.
Most animals that lay eggs, such as birds and reptiles, including most ovoviviparous species, have an oviduct instead of a uterus. Note however, that recent research into the biology of the viviparous (not merely ovoviviparous) skink Trachylepis ivensi has revealed development of a very close analogue to eutherian mammalian placental development.
In monotremes, mammals which lay eggs, namely the platypus and the echidnas, either the term uterus or oviduct is used to describe the same organ, but the egg does not develop a placenta within the mother and thus does not receive further nourishment after formation and fertilization.
Marsupials have two uteri, each of which connect to a lateral vagina and which both use a third, middle "vagina" which functions as the birth canal. Marsupial embryos form a choriovitelline "placenta" (which can be thought of as something between a monotreme egg and a "true" placenta), in which the egg's yolk sac supplies a large part of the embryo's nutrition but also attaches to the uterine wall and takes nutrients from the mother's bloodstream.
Usage examples of "uterus".

He also mentions the instance of congenital atresia of the vagina with hernia of both ovaries into the left groin in a servant of twenty, and the case of an imperforate vagina in a girl of nineteen with an undeveloped uterus.
POLYPI OR POLYPOID TUMORS of the uterus are of three kinds, cystic, mucous and fibrous.
The cystic and mucous varieties may spring from any portion of the mucous surface of the uterus, but they are more frequently met with growing from the mucous membrane lining the cervical canal, and pendent from the mouth of the womb, as represented in Fig.
It so happened in this case that the peritoneum was extremely dilatable, and the uterus, with the child inside, made its way into the peritoneal sac.
Careful examination showed this to be a case of intramural twin pregnancy at the point of entrance of the tube and the uterus, while at the abdominal end of the same tube there was another ovum,--the whole being an example of triple unilateral ectopic gestation.
Those who sleep in warm rooms, or spend much of their time in bed, will continue to have congestion of the uterus, and habitual discharges from this enfeebled organ.

This term designates another unnatural position of the uterus, in which the fundus, or upper part of the organ, falls forward, as illustrated by Fig.
In its natural position, the fundus of the uterus is slightly inclined forward, and any pressure, or forward traction, is liable to cause it to fall still further in that direction.
The author allowed that the uterus was an animal, but he denied the alleged influence, as no anatomist had succeeded in discovering any communication between it and the brain.
