These innervate the muscles of facial expression: Temporal - frontalis, orbicularis oculi and corrugator supercilii. Zygomatic - orbicularis oculi. Buccal - orbicularis oris, buccinator and zygomaticus.

Objective This study sought to critically examine the corrugator supercilii muscle (CSM) in situ, in relation to surrounding bony and soft tissue landmarks.
Corrugator Supercilii Muscle Anatomy The corrugator supercilii muscle is a facial muscle located in the forehead region. It plays a crucial role in facial expressions, particularly in frowning and creating vertical wrinkles between the eyebrows. The corrugator supercilii is a small, narrow, pyramidal muscle close to the eye.
The wrinkles are caused due to loss of skin and muscle fiber elasticity and repeated and habitual contraction of the underlying muscles of facial expression (e.g. corrugator supercilii (CS) muscle ...
Human facial muscles are unique in that they do not cross joints and they function either to open and close the apertures of the face or to tug the skin into intricate movements producing facial expressions. Compared to other skeletal muscles of the body, little is known about the microscopic archit …
Complete resection of the corrugator super-cilii muscle has been advocated for both forehead rejuvenation and in the surgical treatment of migraine headaches.1-3 Unequal corrugator supercilii muscle removal and/or in-complete corrugator supercilii muscle resection after forehead rejuvenation can lead to undesir-able sequelae such as dimpling, depressions, and residual corrugator activity ...
Introduction The corrugator supercilii muscle (CSM) has traditionally been recognized as a primary depressor of the eyebrows, playing a key role in expressing negative emotions and contributing to the formation of glabellar lines. However, recent studies indicate that the CSM may exhibit movements contrary to those previously documented, suggesting a more complex functional role. This research ...

Introduction The corrugator supercilii muscle (CSM) is traditionally described as a small, narrow muscle that originates from the medial end of the supraorbital ridge and inserts into the skin above the middle of the orbital arch [1]. It is com-monly associated with brow depression and the formation of vertical glabellar lines, contributing to expressions of anger or concentration in six (91% ...

Orbicularis oculi is a paired facial muscle that surrounds each orbit and the adjacent periorbital region.

A plexus mainly from the inferior ramus partly from the middle ramus of the temporal branch of the facial nerve enters the corrugator supercilii muscle in the supraorbital area. Because the temporal branch had multiple interconnection among its own rami, selective blocking of the middle ramus cannot promise the elimination of the frown line.
In certain facial surgeries, particularly those involving the eyebrows or forehead, knowledge of the Corrugator Supercilii's location and function is crucial to avoid unintended damage to the muscle, which could result in altered facial expressions or asymmetry.
This is because the anatomy of facial expression is tied directly to the limbic system—the emotional center of the brain. A real laugh is an involuntary physical reaction. A fake one is a motor cortex command. Your brain knows the difference, even if you can't explain why.
The corrugator supercilii is a small but powerful facial muscle that plays a key role in facial expressions, particularly frowning and squinting. When trigger points develop in this muscle, they can cause deep forehead pain, eye strain, and tension headaches, often mimicking migraines, sinus pressure, or eye fatigue.
