muscles of the mouth
The scientific term for the muscles of the mouth is "mimetic muscles" or "facial muscles." These muscles are responsible for facial expressions and movements of the mouth, including actions like smiling, frowning, and speaking. Key muscles in this group include the orbicularis oris, buccinator, and zygomaticus.

No, the mouth is not classified as a sphincter. A sphincter is a circular muscle that constricts or closes an opening in the body, facilitating control over the passage of substances. While the mouth does have muscles that help control its opening and closing, it primarily functions as an entry point for food and air, rather than acting as a sphincter.

Closing the mouth of an inflated balloon helps to keep the air trapped inside. If the mouth is left open, the air can escape and deflate the balloon. Closing the mouth also helps to create pressure inside the balloon, keeping it inflated.
Actually... YES they CAN! The muscles of their jaws are VERY strong for CLOSING their mouths, but VERY WEAK for OPENING their mouths. This why the average man can hold the croc's mouth closed (once it is already closed) while someone else wraps duct tape around the snout, or the person holding the croc's mouth closed can tape it shut.
