Study Notes
- The corpus luteum undergoes regression, transforming into the corpus albicans. The first regression sign is the condensation of the lutein pigment, which appears reddish. The corpus albicans is a connective tissue scar that remains after the regression.
- Uterine tubes (oviducts) are bilateral structures that extend from the ovary to the uterine horns. They consist of an infundibulum, ampulla, isthmus, and outer serosa.
- The mucosa of the infundibulum is lined by a simple columnar or pseudostratified columnar epithelium, which has microvilli and secretes nutrients. The tubes have numerous folds and finger-like projections called fimbriae, which are highly vascularized and collect oocytes during ovulation.
- The myometrium is a thick layer of smooth muscle fibers arranged in a circular and longitudinal manner, with large arteries, veins, and lymphatics between them. It increases in size and number during pregnancy.
- The uterus is the implantation site of the fetus, consisting of horns, a body, and a cervix. The endometrium consists of a superficial functional zone and a deep basal area. It is made up of a simple columnar or pseudostratified columnar epithelium, and is highly vascularized and innervated. Simple branched tubular glands and caruncles are also present.
- The cervix has a sinuous lumen and a histological structure composed of a mucosa/submucosa, muscularis, and serosa. The mucosa is divided into an endocervix and exocervix, and is lined by a columnar epithelium with many goblet cells and simple tubular glands. The muscularis is made up of two layers of smooth muscle fibers, and muscle and elastic fibers are necessary for restoring the structure of the cervix after childbirth.
