Vaginal lubrication - Vaginal discharge. 1  The lubricative fluid contains water, pyridine, squalene, urea, acetic acid, lactic acid, complex alcohols and glycols, ketones, and aldehydes. [1] 2  Vaginal fluid is slightly acidic and can become more acidic with certain sexually transmitted diseases. The normal pH of vaginal fluid is between 3.8 and 4.5, whereas male semen is typically between 7.2 and 8.0 (a neutral substance has a pH of 7.0). Production

Those keratinocytes found in the basal layer of the skin are sometimes referred to as basal cells or basal keratinocytes.
Keratinocytes = cells of the skin producing keratin; so called prickle or MALPIGHIAN cells. Stratum basale = basal layer. is, together with the stratum spinosum, responsible for cell reproduction in this layer; this layer consists of tall cylindrical cells (Epitheliocytus basalis) and melanocytes.tratum spinosum = prickle cell layer. is multi-layered and consists of polygon-shaped cells joined together by desmosomes (visible in the electron microscope as thickening of the cell membrane). In this layer the keratinocytes are joined by tonofibrils (a filament of proteins) like a network.
