The myometrium is the middle layer of the uterine wall, consisting mainly of uterine smooth muscle cells (also called uterine myocytes [1]) but also of supporting stromal and vascular tissue. [2] Its main function is to induce uterine contractions .
The arcuate vessels of the uterus are a component of the blood supply of the uterus.They are arteries and veins that branch from the uterine arteries and veins, respectively, with additional anastomoses from the ovarian arteries and veins, [2] and penetrate and assume a circumferential course in the myometrium.
From innermost to outermost, these layers are the endometrium, myometrium, and perimetrium. [7] The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer; the functional layer thickens and then is shed during the menstrual cycle or estrous cycle.
The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
The endometrium is the innermost lining layer of the uterus, and functions to prevent adhesions between the opposed walls of the myometrium, thereby maintaining the patency of the uterine cavity. [12] During the menstrual cycle or estrous cycle, the endometrium grows to a thick, blood vessel-rich, glandular tissue layer.
The uterus, part of the female reproductive system, is composed of the myometrium and the endometrium. The myometrium is made of smooth tissue and the endometrium lines the uterus. The endometrium is important in pregnancy because it is involved in the development of the placenta and it is where the fertilized egg implants itself during ...
The primary function of an interstitial cytotrophoblast is to anchor the growing fetus to the maternal uterine tissue. These cells may invade the whole endometrium and the proximal third of the myometrium. Once these cells penetrate through the first few layers of cells of the decidua, they lose their ability to proliferate and become invasive.
Oxytocin receptors are expressed by the myoepithelial cells of the mammary gland, and in both the myometrium and endometrium of the uterus at the end of pregnancy. The oxytocin-oxytocin receptor system plays an important role as an inducer of uterine contractions during parturition and of milk ejection.
