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 uterine cavity. This layer is built up after the end of menstruation during the first part of the ...

Vertical section of mucous membrane of human uterus. The uterus has three layers, which together form the uterine wall. 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.

The earliest forms of laminar organization are shown in the diploblastic and triploblastic formation of the germ layers in the embryo.In the first week of human embryogenesis two layers of cells have formed, an external epiblast layer (the primitive ectoderm), and an internal hypoblast layer (primitive endoderm).
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.
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
In the development of the human embryo this takes place by day eight. It is formed when the inner cell mass, also known as the embryoblast, forms a bilaminar disc of two layers, an upper layer called the epiblast (primitive ectoderm) and a lower layer called the hypoblast (primitive endoderm), which will eventually form into fetus.
