Zygomaticus minor

The Zygomaticus minor (pronounced: zy-go-mat-ik-us min-or) is a muscle of the human body, specifically located in the facial region.

Etymology

The term "Zygomaticus" is derived from the Greek word "zygon", which means "yoke". The term "minor" is a Latin word meaning "smaller". Thus, the Zygomaticus minor is the smaller muscle of the two zygomaticus muscles in the face.

Anatomy

The Zygomaticus minor originates from the zygomatic bone, specifically the malar bone, and extends to the orbicularis oris. It is one of the muscles involved in facial expression, particularly in conveying emotions such as smiling or frowning.

Function

The primary function of the Zygomaticus minor is to elevate the upper lip, aiding in expressions of sadness and contempt. It works in conjunction with the zygomaticus major muscle, which is responsible for pulling the corners of the mouth upward and backward, as in smiling.
