Study Notes
Taste Buds
- Microscopic, onion-shaped structures found on the tongue, soft palate, pharynx, and larynx.
- Composed of gustatory cells, gustatory hairs, and supporting cells.
Gustatory Cells
- Contain one gustatory hair extending through a taste pore.
- Located at the apical end of the taste bud.
Gustatory Receptors
- Situated on gustatory hairs, crucial for taste perception.
- Basal ends synapse with sensory neurons; axons integrate into cranial nerves VII (facial), IX (glossopharyngeal), or X (vagus) based on taste bud location.
Papillae
- Structures on the tongue housing taste buds; contribute to the tongue's rough texture.
- Four types include Vallate, Fungiform, Foliate, and Filiform.
Vallate Papillae
- Largest type of papillae; arranged in an inverted V at the back of the tongue.
- Contains taste buds, contributing significantly to taste sensation.
Fungiform Papillae
- Mushroom-shaped papillae widely scattered across the tongue's surface.
- Contains taste buds within its rounded structures.
Filiform Papillae
- Slender, pointed projections that do not contain taste buds.
- Responsible for the rough texture of the tongue, aiding in food manipulation.
Foliate Papillae
- Located primarily on the lateral margins of the tongue.
- Contains taste buds and is more pronounced in children.
