Study Notes
Taste Buds Overview
- Taste receptors are distributed throughout the oral cavity, primarily found in taste buds located on the tongue.
- A taste bud comprises both taste cells and supporting cells.
- Each taste bud contains 50 to 150 taste cells that allow for the perception of taste.
Taste Cells Characteristics
- Taste cells are specialized non-neural epithelial cells with a polarized structure.
- The apical membrane of taste cells features microvilli that increase surface area for taste reception.
- Each taste cell contains specific apical protein receptors or channels that are dedicated to sensing a single type of taste.
- This one-to-one relationship enables the identification of various taste modalities, such as sweet, sour, salty, bitter, and umami.
