Final answer:
The vestibule is lined by stratified squamous epithelium, which provides protection against abrasion.
Step-by-step explanation:
The type of epithelium that lines the vestibule is stratified squamous epithelium.
Stratified squamous epithelium is a type of multi-layered epithelium with flattened cells at the surface. It provides protection against abrasion and is found in areas that are subject to wear and tear, such as the skin and the lining of the mouth and vagina.
Unlike ciliated pseudostratified epithelium with goblet cells, which is found in the respiratory tract and functions in moving particles, the vestibule does not require the movement of particles across its surface.
