Which muscle is responsible for protruding the tongue?

Genioglossus
Tensor veli palatini
Stylopharyngeus
Cricothyroid

The correct answer is: Genioglossus

The genioglossus muscle is responsible for protruding the tongue because it is attached to the front and sides of the tongue and pulls the tongue forward. The other options, including the tensor veli palatini, stylopharyngeus, and cricothyroid muscles, are not responsible for protruding the tongue. The cricothyroid muscle helps in controlling the pitch of the voice, while the tensor veli palatini and stylopharyngeus muscles are involved in functions related to the soft palate and pharynx. Therefore, they do not have a direct role in protruding the tongue.
