orbicularis oculi muscle
musculus orbicularis oculi latin

Her orbicularis oculi muscle making her eyes wide, she says, "Why do you ask?"

The orbicularis oculi muscles are often examined in patients with facial paralysis.

The orbicularis oculi muscle, a muscle around the eye.

This technique causes akinesia of orbicularis oculi muscle without associated facial paralysis.

Facial nerve, which supplies the orbicularis oculi muscle is blocked in addition for intraocular surgeries.

It is located at the medial end of the eyebrow, beneath the frontalis and just above orbicularis oculi muscle.

In typical form, the twitching usually starts in the lower eye lid in orbicularis oculi muscle.

Few printed anatomies include it (Netter, et al.) and many authorities consider it to be part of the orbicularis oculi muscle.

The difference between these operating techniques is the extra repositioning and fixation of the orbicularis oculi muscle in the composite facelift procedure.

Marginal fibres of the palpebral part of the orbicularis oculi muscle is known as "Riolan's muscle".

It becomes noticeable only when the orbicularis oculi muscle becomes weak as in, for example, bilateral facial palsy associated with Guillain-Barré syndrome.

The tape keeps the orbicularis oculi muscle around her eye, the zygomatic major at the corner of her mouth, it keeps all her facial muscles relaxed.

For example, in modeling a human face edge loops should follow the orbicularis oculi muscle around the eyes and the orbicularis oris muscle around the mouth.

His name is also associated with "Horner's muscle", the lacrimal portion of the orbicularis oculi muscle that is sometimes referred to as the "tensor tarsi muscle".

Aging of the face is most shown by a change in position of the deep anatomical structures, which are the platysma muscle, cheek fat and the orbicularis oculi muscle.

Weakness of extraocular muscle groups including, the orbicularis oculi muscle as well as facial and limb muscles may be present in up to 25% of patients with CPEO.

The Hotz-Celsus technique involves the removal of strip of skin and orbicularis oculi muscle parallel to the affected portion of the lid and then the skin is sutured.

In humans, the movements of oculomotor muscles ("eye-blink reflex" or "eye-blink response" assessed using electromyographic recording of orbicularis oculi muscle and by oculography) could be used as a measure.

Apparently, as the authors point out, when you grin, you work both the zygomaticus muscle, which connects the corners of the mouth to the cheekbone, and the orbicularis oculi muscle surrounding the eye.

Compare with a real smile, which raises the lips with the action of zygomaticus major and zygomaticus minor muscles and causes "crow's feet" around the eyes using the orbicularis oculi muscles.

The afferent sensory signals are transmitted by the trigeminal nerve, and the efferent signals come back to orbicularis oculi muscle via the facial nerve, which in turn reflexively contracts causing blinking.

A Duchenne smile involves contraction of both the zygomatic major muscle (which raises the corners of the mouth) and the orbicularis oculi muscle (which raises the cheeks and forms crow's feet around the eyes).

Ptosis associated with CPEO may be corrected with surgery to raise the lids, however due to weakness of the orbicularis oculi muscles, care must be taken not to raise the lids in excess causing an inability to close the lids.

Many docs are injecting a minuscule amount of Botox into the center of the lower lashline's orbicularis oculi muscle to create "a widening of the eye and more of an almond shape," says Boston derm Dr. Ranella Hirsch, who performs the procedure.

Electromyogram (EMG) activity of the orbicularis oculi muscle, which controls eyelid closure, is considered to be the most prominent and sensitive component of blinking (Lavond et al., 1990) and is, thus, the most common behaviorally-derived dependent variable in studies of EBC.
