Uterine glands or endometrial glands are tubular glands, lined by a simple columnar epithelium, found in the functional layer of the endometrium that lines the uterus. Their appearance varies during the menstrual cycle. During the proliferative phase, uterine glands appear long due to estrogen secretion by the ovaries.
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
In women of reproductive age, two layers of endometrium can be distinguished. These two layers occur only in the endometrium lining the cavity of the uterus, and not in the lining of the fallopian tubes where a potentially life-threatening ectopic pregnancy may occur nearby. [4] [5] The functional layer is adjacent to the

The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms every month, in preparation for pregnancy. It is shed off each month when there is no fertilized egg to support. [1] The decidua is under the influence of progesterone. Endometrial cells become highly characteristic.
About the fifth month a ring-like constriction marks the position of the cervix of the uterus, and after the sixth month the walls of the uterus begin to thicken. For a time the vagina is represented by a solid rod of epithelial cells. A ring-like outgrowth of this epithelium occurs at the lower end of the uterus and marks the future vaginal ...
The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1]
During embryological development of the first phase, two separate uterine, cervical and vaginal pockets develop, following which a transverse septum forms across the caudal aspect in the upper two thirds of the vagina, which will dissolve when the lower one third of the vagina (developed from the urogenital sinus) fuses with the upper two ...
