Etymology

In English, this muscle’s name is the greater muscle of the yoke-shaped bone. Zygomaticus comes from the Greek zygon meaning “yoke.” The term minor comes from the Greek meion meaning “lesser.” As is typical in anatomical terminology, this comparative reference clues you into the fact that this is a smaller version of a similar placed larger muscle.

Insertion

Blends with the fibers of the levator labii superioris as both muscles enter and blend with fibers of the superior lip

Action

Elevates the upper lip and works with other muscles in deepening the nasolabial furrow.

Nerve supply

Facial nerve (Cranial nerve VII)

Facial artery and transverse facial artery.
