Question

Why don’t our tongues grow like other muscles since we’re always moving them?

In: Biology

Answer 1

Muscles grow because they need to. If you work your muscles hard and often, they will grow bigger, as long as nutrition is adequate.

Your tongue is a muscle. It is a very specialized muscle. We use it all the time (often), but we never use it harder than we did the day before. Therefore, the muscle of the tongue never needs to get bigger than it is because we will never require it to work harder than it needs to.
