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 basal layer contains stem cells which regenerate the functional layer. [1]
These structures are the future scrotum and labia majora in males and females, respectively. The genital tubercles of an eight-week-old embryo of either sex are identical. They both have a glans area, which will go on to form the clitoral glans (females) or penile glans (males), a urogenital fold and groove, and an anal tubercle.
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.

The upper parts of the uterus remain separate, but the lower parts are fused into a single structure. Found in dogs, pigs, elephants, whales, dolphins, [37] and tarsiers, and strepsirrhine primates among others. Simplex The entire uterus is fused into a single organ. [35] It is found in higher primates, including humans, chimpanzees, and monkeys.
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.
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.
One ovum is released and it passes through the fallopian tube into the uterus. Hormones produced by the ovaries prepare the uterus to receive the ovum. The lining of the uterus, called the endometrium, and unfertilized ova are shed each cycle through the process of menstruation. If the ova is fertilized by sperm, it attaches to the endometrium ...
Endometrial tissue most often grows on or around reproductive organs such as the ovaries and fallopian tubes, on the outside surface of the uterus, or on the tissues surrounding the uterus and the ovaries . [3] It can also grow on other organs in the pelvic region like the bowels, stomach, bladder, or the cervix. [10]
