Which of the following correctly describes the function of the filiform papillae?

• A. Contains taste buds for flavor detection
• B. Provides a rough texture for tactile response
• C. Filters light entering the eye
• D. Transmits visual signals to the brain

Answer: (B)

The function of filiform papillae is correctly described by the option that states they provide a rough texture for tactile response. These structures are the most numerous type of papillae found on the tongue's surface, but they are unusual because they do not contain taste buds. Instead, their primary role is to enhance the tongue's mechanical ability. The keratinized surface of filiform papillae allows them to help grip food, assisting in the process of chewing and swallowing. Their presence contributes to the rough texture of the tongue, which is important for the tactile sensations during the intake of food. In contrast, options that mention taste detection or visual functions do not apply to filiform papillae, as they lack the necessary structures for taste perception and are unrelated to the visual system.
