The uterus is held in position within the pelvis by ligaments, which are part of the endopelvic fascia. These ligaments include the pubocervical ligaments, the cardinal ligaments, and the uterosacral ligaments. It is covered by a sheet-like fold of peritoneum, the broad ligament. From outside to inside, regions of the uterus include:

Cervix uteri – "neck of uterus"
External orifice of the uterus
Cervical canal
Internal orifice of the uterus
Body (Latin: Corpus)
Uterine cavity
Fundus

Layers
The uterus has three layers, which together form the uterine wall. From innermost to outermost, these layers are the endometrium, myometrium, and perimetrium.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 sloughed during the menstrual cycle or estrous cycle. During pregnancy, the uterine glands and blood vessels in the endometrium further increase in size and number and form the decidua. Vascular spaces fuse and become interconnected, forming the placenta, which supplies oxygen and nutrition to the embryo and fetus.The myometrium of the uterus mostly consists of smooth muscle. The innermost layer of myometrium is known as the junctional zone, which becomes thickened in adenomyosis.The perimetrium is a serous layer of visceral peritoneum. It covers the outer surface of the uterus.Surrounding the uterus is a layer or band of fibrous and fatty connective tissue called the parametrium that connects the uterus to other tissues of the pelvis. Commensal organisms are present in the uterus and form the uterine microbiome.
General measures should be recommended for all patients, including moving to an air-conditioned environment if possible, avoiding sweat-provoking activities and occlusive clothing, and taking frequent, cool showers. The use of topical antibacterials (including antibacterial soaps) may shorten the duration of symptoms in miliaria rubra even in the absence of obvious superinfection. Other topical agents that may reduce the severity of symptoms include anti-itch preparations such as calamine or menthol- or camphor-based preparations, and topical steroid creams. Caution should be used, however, with oil-based preparations (ointments and oily creams as opposed to water-based or aqueous lotions) that may increase blockage of the sweat glands and prolong the duration of illness. Other agents have been investigated including supplemental vitamin A and C and vitamin A based medications, but little scientific evidence supports any of the above treatments in reducing the duration of symptoms or frequency of complications. In most tropical areas, the local dispensaries sell prickly heat powder, a talc admixture containing drying milk proteins (labilin) and Triclosan to fight bacterial infection. These include cooling menthol to help alleviate difficulty getting to sleep. This is an effective treatment; the powder stays on the skin longer and treats bacteria dispersed into bed linens, providing a reasonably dry refuge area for healing. Miliaria often covers large areas, and generous use of cortisone may be contraindicated for reasons stated on package warnings. Regular talcum powder does not reduce the rash, but can alleviate burning and itching.
