The corrugator supercilii muscle is a small, [1] narrow, [citation needed] pyramidal muscle [1] of the face. [citation needed] It arises from the medial end of the superciliary arch; it inserts into the deep surface of the skin of the eyebrow. It draws the eyebrow downward and medially, producing the vertical "frowning" wrinkles of the forehead ...
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
It inserts in the fascia of the facial muscles and in the skin above the eyes and nose. [2] Some sources consider the occipital and frontal bellies to be two distinct muscles. However, Terminologia Anatomica currently classifies it as a single muscle, and also includes the temporoparietalis muscle as part of the epicranius.
One method is using Pitanguy's line, which is defined as running from 0.5 cm below the tragus to 1.5 cm above the lateral eyebrow. [1] Another method is to recognize that the temporal branch runs between the lines from the earlobe to the hairline and from the earlobe to the lateral eyebrow.
A tension headache usually feels like a band is wrapped tightly around your forehead, and the pain can extend to your scalp, according to the U.S. National Library of Medicine.
The muscle has no bony attachments. Its medial fibers are continuous with those of the procerus; its intermediate fibers blend with the corrugator and orbicularis oculi muscles, thus attached to the skin of the eyebrows; and its lateral fibers are also blended with the latter muscle over the zygomatic process of the frontal bone.
They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line.
The pain is usually constant, described as aching or burning, and often affects both sides of the face (this is almost never the case in patients with trigeminal neuralgia). The pain frequently involves areas of the head, face, and neck that are outside the sensory territories that are supplied by the trigeminal nerve.
