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 ...

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.

This layer is absent in placenta accreta. [2] Micrograph of decidualized endometrium due to exogenous progesterone. H&E stain. The decidua has a histologically-distinct appearance, displaying large polygonal decidual cells in the stroma. These are enlarged endometrial stromal cells, which resemble epithelium (and are referred to as "epithelioid").
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 ...
The one-celled zygote, a eukaryotic cell formed by a fertilization event between two gametes at the start of embryonic development, undergoes cleavage by mitosis as it travels through the fallopian tube to the uterus. As the zygote undergoes cell division to form two, then four, then eight and then 16 cells (typically by day four after ...
The cytoplasm of uterine epithelial cells contains typical organelles found in other cells, including a nucleus, which is located towards the bottom of the cell with one or more prominent nucleoli, mitochondria, golgi apparatus, endoplasmic reticulum, free ribosomes, lysosomes, vesicles and lipid droplets.
