Salt taste buds are located on which part of the tongue?

• A. Tip of the tongue
• B. Back of the tongue
• C. Sides in front of the tongue
• D. Sides in back of the tongue

Answer: (C)

Salt tastes are detected by taste buds located on the anterior (front) sides of the tongue. The taste receptor cells in these buds respond to sodium ions, letting Na+ ions enter and depolarize the cell, which then sends signals to the brain. This front-side region is where salty flavors are most effectively picked up, which is why the common descriptor places salt on the sides near the front of the tongue. Keep in mind that taste perception is distributed and not strictly confined to rigid zones, but the front-side area is the best-described location for salt.
