Light micrograph of numerous squamous cells from the epithelial lining of the cervix. The sample of cells was removed during the mid-cycle menstrual stage. During the menstrual cycle the stratified squamous epithelium undergoes cyclical changes that includes slight keratinisation of the superficial cells. Here,the cells are of roughly uniform size,with a large cytoplasm and a small,central nucleus. Throughout the cycle the superficial cells produce glycogen,which is metabolised by commensal bacteria (Lactobacillus sp.) to produce lactic acid that inhibits growth of disease-causing microorganisms.
