What is the meaning of Filiform Papillae?
Filiform Papillae is widely used term in Dental Anatomy.
Filiform papillae are one of the four types of oral papillae found on the dorsal surface (top surface) of the tongue. They are slender, cone-shaped structures that cover the majority of the tongue’s surface and give it a rough texture. Unlike the other types of papillae, such as fungiform and circumvallate papillae, filiform papillae do not contain taste buds.
Functionally, filiform papillae play important roles in enhancing the tongue’s ability to manipulate and process food. They achieve this by increasing the surface area of the tongue and providing friction, which aids in the movement and manipulation of food during chewing and swallowing. Additionally, they also help in the mechanical cleansing of the oral cavity by increasing the effectiveness of saliva distribution.
Under a microscope, filiform papillae appear as finger-like projections that are composed of lingual epithelium and keratinized stratified squamous epithelium. These papillae are typically concentrated in the center and anterior regions of the tongue, gradually decreasing in density towards the back of the tongue.
