This lecture covers the practical aspect of the third week, focusing on downloading and using the Biolucida application to study histological sections. The instructor demonstrates how to navigate through histological collections, identifying different epithelial layers, recognizing cellular characteristics, and discussing the importance of glycogen-rich epithelium in the cervix. The lecture also delves into the structure of the cervix, highlighting the junction between stratified and simple epithelium, the presence of Nabothian cysts, and the role of the cervical surface in HPV infection. Detailed observations of epithelial layers, glandular structures, and vascular components provide insights into the histology of the cervix and its functional significance.
