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

• A. Back of the tongue
• B. Front of the tongue
• C. Tip of the tongue
• D. Sides of the tongue

Answer: (A)

Bitter tastes are detected primarily at the back of the tongue because the posterior region contains many taste buds, especially in the circumvallate papillae, that are highly sensitive to bitter compounds. This placement helps protect you by signaling potentially toxic substances early, prompting you to spit or swallow less. While taste buds exist across the tongue, bitterness is strongest toward the rear, whereas the front is more associated with sweet and the sides with sour and salty, with some overlap.
