This is a slender band of muscle on each side of the face that arises from the zygomatic bone, inserts into the upper lip. Its' action is smiling.
The Zygomaticus is the primary muscle used in smiling.
zygomaticus major and minor
Zygomaticus major and zygomaticus minor are facial muscles of the human body. Yellow marrow is found in long bones of the human body.
A synergist muscle of the zygomaticus is the risorius muscle. While the zygomaticus major and minor are primarily responsible for elevating the corners of the mouth during smiling, the risorius assists by pulling the mouth laterally, enhancing the expression of joy or amusement. Together, these muscles contribute to facial expressions, particularly in the lower part of the face.
The zygomaticus muscle is located in the face and is responsible for controlling facial expressions, particularly in smiling. It runs from the cheekbone to the corners of the mouth, allowing for upward movement of the lips.

Zygomaticus
The antagonist of the zygomaticus muscle, which is responsible for smiling by elevating the corners of the mouth, is the platysma. The platysma can pull down on the corners of the mouth, contributing to expressions of sadness or tension. Additionally, other muscles like the depressor anguli oris also function to counteract the actions of the zygomaticus.
