Zygomaticus minor muscle

Zygomaticus minor muscle (shown in red).

The Zygomaticus minor muscle is a muscle of the human body, specifically located in the face. It is one of the muscles responsible for facial expression, and is primarily involved in the action of smiling.

Structure[edit | edit source]

The Zygomaticus minor originates from the malar bone and extends to the orbicularis oris muscle, where it inserts. It is a slender and narrow muscle, located between the Zygomaticus major and the Levator labii superioris.

Function[edit | edit source]

The primary function of the Zygomaticus minor is to elevate the upper lip, aiding in the expression of happiness, such as when smiling or laughing. It also assists in exposing the upper teeth during such expressions.

Clinical significance[edit | edit source]

Damage to the Zygomaticus minor can result in facial paralysis, leading to an inability to fully express emotions through facial expressions. This can be a symptom of Bell's palsy or other neurological disorders.
