The anatomy of kissing
Kissing is a complex behavior that requires significant muscular coordination; in fact, a total of thirty-four to thirty-six muscles working cooperatively. The most important muscle involved is the orbicularis oris muscle, which is used to pucker the lips and informally known as the kissing muscle. The tongue can also be an important part of the kiss. Lips have many nerve endings so they are sensitive to touch and bite.
