The antagonist of the orbicularis oris muscle is the depressor anguli oris muscle. It is responsible for depressing the angle of the mouth, which opposes the action of the orbicularis oris muscle that closes and puckers the lips.

A muscle that lowers or depresses a part of the body is called a depressor muscle. These muscles function by contracting to reduce the angle between body parts or to move them downward. For example, the depressor anguli oris muscle is responsible for lowering the corners of the mouth. In general, depressor muscles play a key role in facial expressions and various movements throughout the body.
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.

Frowning primarily involves the contraction of the corrugator supercilii and the procerus muscles, which are located in the forehead and between the eyebrows. The corrugator supercilii pulls the eyebrows downward and together, while the procerus helps to wrinkle the skin over the bridge of the nose. Additionally, the depressor anguli oris, located at the corners of the mouth, contributes to the downward movement associated with frowning. Together, these muscles create the characteristic facial expression of displeasure or concern.
When the term "levator" is part of a muscle's action, it typically indicates that the muscle is involved in lifting or elevating a specific body part. For example, the levator scapulae muscle elevates the scapula (shoulder blade), while the levator anguli oris muscle elevates the angle of the mouth when smiling.
