What is the Difference Between Fungiform and Filiform Papillae?
🆚 Go to Comparative Table 🆚Fungiform and filiform papillae are two types of papillae found on the human tongue, and they have distinct structures and functions:
Fungiform Papillae:
- Shaped like mushrooms or fungus.
- Found scattered across the tongue's surface, with 200 to 400 papillae present.
- Contain taste buds on their upper surface, which can distinguish between sweet, sour, bitter, salty, and umami tastes.
- Also senses temperature and helps with speech, swallowing, and singing.
- Innervated by the seventh cranial nerve, specifically via the submandibular ganglion, chorda tympani, and geniculate ganglion ascending to the solitary nucleus in the brainstem.
Filiform Papillae:
- Conical in shape, with the vertex pointed caudally.
- Most common type of papillae, found on the rostral, dorsal, and lateral surfaces of the tongue.
- Do not contain taste buds.
- Function as a coating mechanism for the tongue, creating a rough texture on the surface that helps with chewing, speaking, and cleansing the mouth.
In summary, fungiform papillae are mushroom-shaped and contain taste buds, while filiform papillae are cone-shaped and do not contain taste buds. Both types of papillae play essential roles in the sensory and motor functions of the tongue.
Comparative Table: Fungiform vs Filiform Papillae
Fungiform and filiform papillae are two different types of lingual papillae on the tongue. Here is a table comparing their differences:
Feature | Fungiform Papillae | Filiform Papillae |
---|---|---|
Shape | Club-shaped | Cone-shaped |
Location | Tip of the tongue | Anterior 2/3 of the tongue |
Taste Buds | Contains taste buds | Does not contain taste buds |
Taste Sensation | Can distinguish 5 tastes (sweet, sour, bitter, salty, umami) | N/A |
Core | Contains connective tissue | Contains irregular connective tissue cores with keratin-containing epithelium |
Other Features | Not available | Contains elastic fibers, giving them a firmer and more elastic nature |
Fungiform papillae are club-shaped and found on the tip of the tongue, while filiform papillae are cone-shaped and found on the anterior 2/3 of the tongue. Fungiform papillae contain taste buds, which can distinguish the five tastes: sweet, sour, bitter, salty, and umami. In contrast, filiform papillae do not contain taste buds and have a core of irregular connective tissue with keratin-containing epithelium. Additionally, filiform papillae contain elastic fibers, giving them a firmer and more elastic nature compared to other types of papillae.
