The Orbicularis Occuli Muscle controls the movement of your eyelids. It is located in the face and it closes the eyelids. It is the only muscle capable of this.
If the orbicularis occuli muscle loses it's function, then there would be no way
whatsoever to close the eye. In extreme cases, if the muscle does not work, necessitating eye drops at the minimum is used for the removal of the eye in extreme cases.
The palpebral (eyelids) portion acts involuntary in sleep or blinking. It closes the eyelids gently. The orbital (sockets) portion therefore develops conscious control. When the whole of the muscle is in action, the skin of the temple, cheek and forehead is brought toward the medial angle of the orbit and the eyelids are firmly closed. That occurs in photophobia (cannot withstand light/fear of light). Therefore, the skin that is drawn upon is thrown into folds.
Every time the eyelids close because of the orbicularis muscle, the medial palpebral ligament is tightened. Therefore, the wall of the lacrimal sac is drawn lateralward and forward, therefore, a vacuum is made in it and the tears are sucked along the lacrimal canals. The lacrimal draws the eyelids and ends of the lacrimal canals medialward. And that compresses them against the globe of the eye's surface. That is it's favourite position to produce tears.

What else can I help you with?
Name a muscle that closes the eye?
Orbicularis oculi muscle
What muscle roles your eye counter clockwise?
The primary muscle responsible for moving the eye counterclockwise is the superior oblique muscle, which is innervated by the trochlear nerve (cranial nerve IV). Additionally, the lateral rectus muscle, innervated by the abducens nerve (cranial nerve VI), assists in this movement by pulling the eye outward. Together, these muscles coordinate to achieve the desired counterclockwise rotation of the eye.
What is the main depressor of the eyelid?
The main depressor of the eyelid is the orbicularis oculi muscle. This muscle encircles the eye and is responsible for closing the eyelid. Its contraction enables blinking and helps to protect the eye from irritants and excessive light. Additionally, the levator palpebrae superioris muscle works to raise the eyelid, balancing the functions of these muscles.
Can the Ciliary Muscle be under person's conscious control?
The straight answer is YES. You can try it yourself by closing one eye and making the computer screen blurry (thats your ciliary muscle working). However the muscle's primary control is involuntary (you may find yourself fighting it as you try to make the screen blurry). There is debate about the topic because it is a smooth muscle and it is innervated by autonomic nerves, both of which are typically exclusively involuntary. Also be careful: on exams answer NO, since typical questions will be asking for the primary function.
What does the inferior oblique muscle of the eye do?
The inferior oblique muscle of the eye, abducts, elevates and laterally rotates the eye
What muscle gives the eye its color?
The iris gives the eye it's color. It is not a muscle.
What is affected first when drinking eye muscle leg muscle or arm muscle?
eye muscles according to traffic school.
Which muscle closes the eye and produces blinking and squinting?
The Orbicularis oculi muscle squints the eye.
What is the composite sphincter muscle encircling each eye?
Orbicularis oculi is a wide flat muscle that encircles the eye.
Which extrinsic eye muscle originates from the sphenoid bone?
The extrinsic eye muscle that originates from the sphenoid bone is the superior rectus muscle. This muscle is responsible for elevating the eye and helps in adduction and intorsion. It is one of the six extraocular muscles that control eye movements.
Is you eye socket a muscle?
yes you eye socket be dah pimpedist muscle in da whole bods
Is the eye an involuntary muscle?
The intrinsic muscle are involunary and respond to light intensity and required focal langth without conscious intervention. The extrinsic muscle of the eye are volunary and move the eye to look around under conscious control. The eye itself is ofcourse not a muscle at all.
