Preferred Label : uterus;
Uberon definition : the female muscular organ of gestation in which the developing embryo or fetus is
nourished until birth;
Uberon Development note : Two uteruses usually form initially in a female fetus, and in placental mammals they
may partially or completely fuse into a single uterus depending on the species. In
many species with two uteruses, only one is functional. Humans and other higher primates
such as chimpanzees, along with horses, usually have a single completely fused uterus,
although in some individuals the uteruses may not have completely fused [Wikipedia:Uterus];
Uberon Homology note : An infundibulum, uterine tube, uterus, and vagina also differentiate along the oviducts
of eutherian mammals.[well established][VHOG];
Uberon Taxon note : Most animals that lay eggs, such as birds and reptiles, have an oviduct instead of
a uterus. In monotremes, mammals which lay eggs and include the platypus, 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 uteruses, 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.;
