We just learned about the Taste Buds.
Another part of the tongue is the Filiform Papillae.
The lingual papillae that we learned about come in a few different shapes and sizes.
One of those is the filiform papillae, which are small and cone shaped, with small threads at the top.
These papillae do not have any taste buds, they are only used by the tongue for feeling, and to give the tongue a rough feeling.
The tongue has more filiform papillae than any other type of papillae.
