Vaginal Histology Catalog

The vaginal wall is composed of mucosa, muscularis, and adventitia. The vaginal mucosa forms many horizontal folds, and the mucosal epithelium is a non-keratinized stratified flat epithelium, which is thicker. 
Generally, although the lower layer cells contain transparent keratin particles, they do not show keratinization. 

Vaginal Epithelium

In patients with vaginal prolapse, keratinization may occur in the local epithelium. The shedding and renewal of vaginal epithelium and certain periodic changes are affected by ovarian hormones. 

Estrogen promotes thickening of the vaginal epithelium and allows cells to synthesize large amounts of glycogen. The vaginal epithelium is thickest in the late period of hyperplasia of the menstrual cycle. 
Representation of Vaginal epithelial cells

Vaginal epithelial cells shed significantly

When the level of estrogen in the late endometrial secretion decreases, the vaginal epithelial cells shed significantly and the epithelium becomes thinner. 

Clinically, the smear of vaginal epithelial cells can be observed to understand the endocrine function of the ovary.

In addition to vaginal epithelial cells, there are exfoliated cells in the cervix and endometrium, so vaginal smear examination is also a method for diagnosing genital tract tumors
After the vaginal epithelial cells are shed, the intracellular glycogen is decomposed into lactic acid by the lactobacilli in the vagina, so that the vaginal secretions remain acidic and have a certain antibacterial effect. 

After menopause, the mucosa of the obstructive channel shrinks, the epithelium becomes thinner, the number of shed cells is less, the pH of the vaginal fluid rises, and the bacteria are prone to multiply and cause vaginitis. 

The superficial layer of the mucosal lamina propria is denser connective tissue, rich in capillaries and elastic fibers, and the deep layer is rich in venous plexus.

Adult vaginal mucosa

The vaginal muscle layer is smooth muscle, which is weak, and the muscle bundles are spiral, arranged in a lattice, and the elastic fibers in the connective tissue are rich. 

This structural feature of the vaginal muscle layer makes the vaginal wall easy to expand. There is a circular sphincter composed of skeletal muscle outside the vagina, called urethral vaginal sphincter. The outer membrane is dense connective tissue rich in elastic fibers.

Microbiology FAQs. Course and Journal

Microbiology (Academic Subject and Medical Department) Meaning of Microbiology : Microbiology is one of the branches of biology. It is to study the morphological structure, growth and reproduction of various micro-organisms (bacteria, actinomycetes, fungi, viruses, Rickettsia, mycoplasma, chlamydia, spirochete protozoa and single-cell algae) at the molecular, cellular or population level. It is also a name of medical department that studies and applies the subject. It also studies physiological metabolism, genetic variation, ecological distribution and taxonomic evolution and other basic laws of life activities, and apply it to science in the fields of industrial fermentation, medical hygiene and bioengineering. Microbiology is a science that studies the laws of life activities and biological characteristics of various tiny organisms.   Discipline Name:     Microbiology Subject:     Biology Definition:     One of the branches of biology studying micro organisms

Herpes Virus Infections Biological Traits Immunity and Pathogenicity

Infections Biological Traits Pathogenicity of  Herpes Virus Herpes simplex virus (HSV) is a typical representative of herpes virus. It is named because herpes simplex occurs in the acute phase of infection.  It can cause a variety of human diseases, such as gingivostomatitis, keratoconjunctivitis, keratoconjunctivitis, encephalitis, and reproductive system infections and newborn infections. After infecting the host, a latent infection is often established in nerve cells. After activation, asymptomatic detoxification will occur. The chain of transmission will be maintained in the population and it will circulate repeatedly.
