The orbicularis oris muscle is often referred to as the "kissing muscle." This muscle surrounds the mouth and forms the lips, playing a crucial role in puckering the lips for kissing.
The orbicularis oris works in conjunction with the buccinator and pharyngeal constrictor muscles, forming a functional unit called the "buccinator mechanism." This mechanism is essential for various orofacial functions, including:
- Swallowing
- Sucking
- Whistling
- Chewing
- Vowel pronunciation
- Kissing
It is important to note that the orbicularis oris muscle is not the only muscle involved in kissing. Other muscles, such as the zygomaticus major, contribute to the expression and movement of the lips during a kiss. However, the orbicularis oris muscle is considered the primary muscle responsible for puckering the lips.
