Tongue and Lip Sensory Powers: More Than Just Taste Buds

Our tongues and lips have an incredible density of nerves, giving them remarkable tactile capabilities. In fact, looking at an object can make us vividly imagine what it would feel like to lick or touch it with our lips. This is why babies put everything in their mouths and get important stimulation from this act. While we eventually stop this behavior as we get older, it's still a strange and fascinating aspect of our anatomy.
