A cervical smear primarily samples the squamous epithelium of the ectocervix and vagina. This epithelium is composed of several maturational layers, each represented by distinct cell types in cytology. Basal cells are the deepest, regenerative layer. Parabasal cells represent early maturation and are common in atrophic smears. Intermediate cells are predominant in reproductive-age women and reflect active maturation under hormonal influence. Superficial cells are the final, fully mature cells with pyknotic nuclei. In contrast, endometrial cells are not part of the squamous epithelial lining; they are glandular cells originating from the lining of the uterine cavity. They may appear in cervical smears, especially during menses or the early proliferative phase of the menstrual cycle, but they are not a normal component of the squamous epithelial spectrum routinely seen. Their presence outside the expected timeframe can be clinically significant.
