It is the space in the uterus that is lined by a layer of mucus membranes.
The endometrium is the innermost layer of the uterus that contains the lining which is responsible for accepting and nourishing a fetus during the pregnancy process. The lining of this cavity changes with every monthly cycle in response to the primary female hormones produced by the ovaries: estrogen and progesterone. Normal Uterus. The uterus is a inverted pear shaped muscular organ located in the middle of the female pelvis, between the bladder and the rectum. It is suspended by ligaments in the abdominal cavity. These often appear localized on the outside surface of the uterus or may be attached to the outside surface by a pedicle. Submucosal (submucous) fibroids are located inside the uterine cavity beneath the inner lining of the uterus. Intramural fibroids are located within the muscular wall of the uterus.  The female reproductive system is located in the pelvis. Uterus is the site of fertilization and for the growth of embryo the normal uterine cavity and endometrial lining are very important in the maintenance of pregnancy. Endometrial cavity has a triangular shape and its base is formed by the fundus internal surface. The uterine cavity and the lining of endometrial are both necessary so that pregnancy is maintained and a child is conceived. The endometrial cavity, or endometrium, is the space in the uterus that is lined by a layer of mucus membranes, which renew themselves monthly as part of a healthy female reproductive cycle. One of the most common issues involving endometrial cells is endometriosis. Medical professionals refer to the space surrounded by a layer of mucus membranes that lines the uterus as the endometrial cavity. The cells that make up this layer are called endometrial cells. In humans, the cells of the cavity renew themselves monthly, as part of the reproductive cycle of healthy women. From Wikipedia, the free encyclopedia. An interstitial pregnancy is a uterine but ectopic pregnancy; the pregnancy is located outside of the uterine cavity in that part of the fallopian tube that penetrates the muscular layer of the uterus. The term cornual pregnancy is sometimes used as a synonym, but remains ambiguous as it is also applied to indicate the presence of a pregnancy located within the cavity in one of the two upper horns of a bicornuate uterus. 1 Subserosal-on the outside surface of the uterus. 2  Intramural-within the muscular wall of the uterus. 3  Submucous-bulging in to the uterine cavity. 4  The only type that is supposed to have a large impact on reproductive function (unless they are large or numerous) is the submucous type that pushes in to the uterine cavity.  The part of the Fallopian tube that is located in the uterine wall and connects the remainder of the tube to the endometrial cavity is called its interstitial part, hence the term interstitial pregnancy; it has a length of 1–2 cm and a width of 0.7 cm. The term cornual pregnancy is sometimes used as a synonym, but remains ambiguous as it is also applied to indicate the presence of a pregnancy located within the cavity in one of the two upper horns of a bicornuate uterus. The mucus membranes that are found lining the uterus is the endometrial cavity. This cavity is like slit which is flattened antero-posteriorly. Endometrial cavity has a triangular shape and its base is formed by the fundus internal surface. The uterine cavity and the lining of endometrial are both necessary so that pregnancy is maintained and a child is conceived. The endometrium lining is formed periodically and is shed if a pregnancy doesn't occur
