Answer :
Final answer:
The "kissing muscles" refers to the orbicularis oris, which controls lip movements, and the buccinator muscle, located in the cheeks.
Explanation:
The two facial muscles that are commonly known as the "kissing muscles" are the orbicularis oris and buccinator muscles. The orbicularis oris is a circular muscle that wraps around the mouth, controlling the movements of the lips. It is vital for functions such as puckering the lips during kissing.
The buccinator muscle, on the other hand, is located in the cheeks. It helps flatten the cheek against the teeth and is used when blowing air out of the mouth, sucking, and chewing, helping to keep the food within the oral cavity while eating.
Both muscles demonstrate the complexity of our facial expressions and movements associated, especially with the intimate act of kissing. Their significant representation on the cerebral cortex emphasizes humans' fascination with these expressions and actions.
