Well-developed mentalis muscles result in a dimple in the chin. The lower lip receives the majority of its vertical support from the mentalis muscle (MT), which is the only muscle that lifts the lower lip and chin.
<h3>What is a mentalis muscle?</h3>
The lower lip receives the majority of its vertical support from the mentalis muscle (MT), which is the only muscle that lifts the lower lip and chin.
At the end of the chin, there is a pair of muscles called the mentalis. It serves as the lower lip's main muscle. The mentalis extends vertically from the lower lip to the bottom portion of the chin and arises from the mandible (lower jaw). For the lower lip to pout, this muscle gives it stability.
Together, these muscles shape facial emotions involving the lips, chin, and cheeks. The mentalis muscle lifts everts and protrudes the lower lip while wrinkling the chin's skin to convey uncertainty and contempt.
Therefore, the correct answer is option A. a dimple in the chin.
