Note the noncornified stratified squamous epithelium of the vagina and vaginal portion of the cervix "ectocervix". Find the well developed cervical mucous glands and the abrupt change of stratified squamous to simple columnar epithelium near the external os of the cervical canal, the junction between endocervix and ectocervix. This region of epithelial transition is clinically important since it is here that many carcinomas of the cervix develop. This is a low power view of a section through vagina. The vaginal mucosa is thrown up into numerous folds, or rugae, which consist of a stratified squamous epithelium supported by a well-vascularized lamina propria. A muscularis layer, comprised of smooth muscle tissue, and an outer adventitial layer, both poorly preserved in this specimen, form the wall of the vagina.

Flashcards - Ch. 5 Epithelial Tissue

The female reproductive system includes paired ovaries, which produce female germ cells oocytes or eggs and the female hormones estrogen and progesterone. The ovary consists of a cortex, which houses the maturing eggs in follicles, and a medulla, in which blood vessels and nerves enter the structure. Mature eggs are ovulated from the ovary into the oviduct. The egg is received by the funnel shaped infundibulum of the oviduct and travels down the tube through the ampulla, isthmus, and intramural portions of the oviduct to enter the uterus. The uterus is lined by a special mucus membrane, the endometrium, which undergoes cyclic changes in preparation for the implantation of the fertilized egg. The uterus runs continuous with the cervix, which in turn leads into the vagina. The mammary glands are the major accessory glands.

Epithelium

Click to see full answer. Keeping this in consideration, where is stratified epithelial tissue found in the body? Transitional epithelia are found in tissues that stretch and it can appear to be stratified cuboidal when the tissue is relaxed, or stratified squamous when the organ is distended and the tissue stretches. It is sometimes called urothelium since it is almost exclusively found in the bladder, ureters and urethra.
