Microscopic Photos of Reproductive System Tissue Slides 4 years, 1 month ago The wall of the vagina lacks glands and consists of mucosal, muscular, and adventitial layers. The vaginal mucosa epithelium is stratified squamous, with a thickness of 150-200 μm in adults. Stimulated by estrogens, the epithelial cells synthesize and accumulate glycogen. Bacteria metabolize glycogen to lactic acid, causing a relatively low pH within the vagina, which protects against pathogenic microorganisms. The lamina propria of the mucosa is rich in elastic fibers. The mucosa typically contains lymphocytes and neutrophils in large quantities.The vagina’s muscular layer comprises two indistinct layers of smooth muscle, disposed as circular bundles next to the mucosa and as thicker longitudinal bundles near the adventitial layer. The adventitia’s dense connective tissue is also rich in elastic fibers, making the vaginal wall strong and elastic. The outer layer contains an extensive venous plexus, lymphatics, and nerves.
