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.
