Preferred Label : myometrium;
Uberon definition : the smooth muscle coat of the uterus, which forms the main mass of the organ and surrounds
and supports the endometrium;
Uberon synonym : tunica muscularis (myometrium);
Uberon related term : uterine myometrium; uterine smooth muscle;
Uberon Function note : The myometrium stretches (the smooth muscle cells expand in both size and number)
during pregnancy to allow for the harboring of the pregnancy, and contracts in a coordinated
fashion during the process of labor. After delivery the myometrium contracts to expel
the placenta and reduce blood loss.;
Uberon Homology note : In all mammals, the uterus develops as a specialization of the paramesonephric or
Müllerian ducts, which gives rise to the infundibula, oviducts, uterus, cervix, and
anterior vagina. Morphogenetic events common to development of all uteri include:
1) differentiation and growth of the myometrium, 2) differentiation and morphogenesis
of the endometrial glands, and 3) organization and stratification of endometrial stroma.
Uterine development is initiated in the fetus, but is only completed postnatally with
differentiation and development of the endometrial glands.[well established][VHOG];
