The Kiss
The anatomy of a kiss
It may feel like the most natural thing in the world, but kissing is far from easy. To undertake the task, six major muscles around the mouth help to pucker up the upper lips, pull up the corners of the mouth, and pull down the lower lips. And don’t forget the effort it takes to cross your fingers that it’s worth it.
It’s not just the mouth; the whole body is involved in the act of kissing. When lips hit lips, five of the 12 pairs of cranial nerves, responsible for smell, taste, vision and facial expressions, are excited. Blood vessels expand, cheeks flush, pupils dilate, and the heart pumps a higher level of oxygen to the brain.
