The corrugator supercilii muscle acts upon the skin of the forehead superior to the middle of the supraorbital margin, [1] drawing the eyebrow inferomedially to produce vertical wrinkles of the forehead [3] just superior to the nose. [1] It is the "frowning" muscle, and may be regarded as the principal muscle in the expression of suffering. [4]
Lowering eyebrows (e.g., scowling, frowning) Skin underneath eyebrows: Inferior: Corrugator supercilii: Frontal bone: Skin underneath eyebrow Flaring nostrils: Nasal cartilage (pushes nostrils open when cartilage is compressed) Inferior compression; posterior compression: Nasalis: Maxilla: Nasal bone: Raising upper lip: Upper lip: Elevation ...
The movements of the muscles in the forehead produce characteristic wrinkles in the skin. The occipitofrontalis muscles produce the transverse wrinkles across the width of the forehead, and the corrugator supercilii muscles produce vertical wrinkles between the eyebrows above the nose. The procerus muscles cause the nose to wrinkle. [6]
The neck is just like the face; repeatedly making a muscle movement that creates a wrinkle will ultimately cause that wrinkle to become permanent, points out Alexandra Bowles, MD, a board ...
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.
An eyebrow is an area of short hairs above each eye that follows the shape of the lower margin of the brow ridges of some mammals.In humans, eyebrows serve two main functions: first, communication through facial expression, and second, prevention of sweat, water, and other debris from falling down into the eye socket.
Complications are said to be rare and minor when a forehead lift is performed by a surgeon trained in the technique. However, it is possible for the surgical process to damage the nerves that control eyebrow and forehead movements. Hair loss can also occur along the scar edges in the scalp when an incision is made through the hairline.
