the foliate papillae are involved in the sensations of taste and have taste buds
embedded in their surfaces. The foliate papillae are clustered into two groups positioned on each side of the tongue, just in front of the V of the vallate papillae. Their name is descriptive, with each of these papillae having an elongated fold that looks like a leaf seen edge-on. Taste buds on these types are scattered over the surface of the fungiform papillae, and on opposed walls of the foliate papillae.it is normal to have one side larger than the other side.
