The correct answer is:
b) Levator labii superioris
The levator labii superioris muscle is primarily responsible for elevating the upper lip. This is supported by several points in the search results:
1. From source [1]: “Elevating and everting the upper lip: levator labii superioris, levator labii superioris alaeque nasi, risorius, levator anguli oris, zygomaticus major and zygomaticus minor muscles.”
2. From source [2]: “The LLS elevates and everts the upper lip, particularly during smiling.”
3. From source [3]: “Levator labii superioris is one of the muscles of facial expression. Literal meaning: The muscle that lifts the upper lip.”
While the other muscles mentioned in the options have different primary functions:
– Orbicularis oris: Closes the lips
– Zygomaticus major: Elevates and lateralizes the corner of the mouth (for smiling)
– Buccinator: Compresses the cheekTherefore, the levator labii superioris is the muscle specifically responsible for elevating the upper lip.
