Anatomy of the Muscles of the Face

muscles of the face

If you’ve ever wondered which muscles on your face control your facial expression, read this article. You’ll learn the anatomy of the muscles that make our facial features look as natural as possible. Among the most important of these are the corrugator supercilii, Orbicularis oculi, and Zygomaticus major. In addition, this article will provide information about the nasalis, or the muscle at the base of our nose.

Orbicularis oculi

The Orbicularis oculi is a pair of facial muscles. The palpebral orbicularis shortens the canaliculi of the nasolacrimal duct system and pulls the lacrimal sac laterally and forward to create a vacuum and draw tears into the lacrimal sac. This muscle develops during the twelfth week of pregnancy from the mesoderm of the eyelids and the second pharyngeal arch. Blood supply is provided by the facial artery and the ophthalmic artery.

Zygomaticus major

The zygomaticus major is the largest muscle in the face. Its anatomic description is somewhat complicated. Its origin is anterior to the malar eminence, while its course is more cranial. This article explains how to locate the zygomaticus major muscle on the face. This information will be useful for clinical and cadaver studies. Read on for a more detailed description of this muscle.


The Nasalis muscles are the facial muscle attached to the nasal cartilage on each side of the midline. The muscle consists of two parts: the transverse and alar portions. The transverse portion originates from the maxilla and extends towards the dorsum of the nose, where it inserts into the aponeurosis. The alar portion originates from the lateral incisor and extends downward into the nasal bridge. Together, these two muscles serve to open and close the nose.

Corrugator supercilii

The corrugator supercilii muscles are found on the forehead. These muscles receive arterial blood supply from the ophthalmic and superficial temporal arteries. Dissection of the muscle in humans reveals the anatomy and function of these muscles. In 84% of cases, the muscle has a lateral attachment to the underlying bony anatomy. A surgical procedure to remove the muscle may result in facial rejuvenation or treatment of migraine headaches.


The suprahyoid muscles of the face are a group of four thin muscle groups that attach to the hyoid bone. They help elevate and depress the mandible during swallowing. These muscles also receive arterial supply from the facial, occipital, and lingual arteries. The stylohyoid muscle, located in the posterior belly of the digastric muscle, is responsible for initiating the swallowing action.


The epicranial muscle is the uppermost layer of the cranium and comprises two parts, the frontalis and the occipitalis. The frontalis controls the movements of the forehead and the occipitalis controls the backward movement of the scalp, raising the eyebrows. The two sections work in cooperation with a tendon. The frontalis and occipitalis form a complex, three-layered structure.
