What are the six things attached to each eye that control and coordinate the movements of the eye?
The six extraocular muscles control and coordinate the movements of the eye: the lateral rectus, medial rectus, superior rectus, inferior rectus, superior oblique, and inferior oblique muscles. Each muscle is responsible for a specific movement of the eye in different directions.
Superior oblique muscle is contracted which way will rotate?
When the superior oblique muscle contracts, the eye will rotate in a downward and outward direction. This movement is known as intorsion and abduction of the eye. It helps to move the eye downwards and away from the nose.
Can you go blind from having Superior Oblique Myokymia?
Superior Oblique Myokymia is a rare condition characterized by involuntary twitching of the eye muscles, specifically the superior oblique muscle. It is not known to cause blindness, but it can lead to visual disturbances and discomfort. Treatment options such as medications or surgery can help manage symptoms.
What muscle turns the eye inferior and medially?
The inferior rectus muscle is responsible for turning the eye downward and medially.
What cranial nerve is responsible for moving the eye laterally?
There are three cranial nerves that innervates muscle to move the eye. The main cranial nerve that controls eye movement is occulomotor nerve (CN III). It is responsible for inferior rectus, superior rectus, medial rectus, and inferior oblique. Lateral rectus muscle is innervated by abducens nerve (CN VI). Superior oblique muscle is innervated by trochlear nerve (CN III).

What is the Trochlea of the superior oblique muscle of the eye?
The Trochlea Nerve (cranial nerve 4) controls the superior oblique muscle of the eye. It turns the eye laterally and downwards.
What is the Ipsilateral antagonist of right inferior oblique ocular muscle?
The ipsilateral antagonist of the right inferior oblique muscle is the right superior oblique muscle. The superior oblique muscle acts to depress and abduct the eye, while the inferior oblique muscle acts to elevate and abduct the eye.
What are the extrinsic eye muscles?
Superior Rectus Medial Rectus InferiorRectus Superior Oblique Inferior Oblique Lateral Rectus
Why does superior oblique tendon pass through the trochlea?
The superior oblique muscle passes through the trochlea to change the direction of its pull, allowing it to have a more efficient and effective action on the eye. This unique anatomical arrangement helps the eye move smoothly and coordinate its movements for binocular vision.
Which muscle type allows you to direct your eyeballs?
The muscles are called the extraocular muscules, and they are the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique.
What is Superior oblique myokymia?
Superior oblique myokymia is a rare eye condition characterized by involuntary, rhythmic contractions (twitching) of the superior oblique muscle of the eye. This can lead to symptoms such as episodic vertical or torsional diplopia (double vision) and may be triggered by stress, fatigue, or caffeine. Treatment options include medications, botulinum toxin injections, and in severe cases, surgical intervention.

What eye muscle control the movement of the eye?
A total of six muscle move each eyeball, 4 rectus muscels and 2 obliques. The superior, inferior, lateral and medial rectal muscle all pull the eye to be looking more in ther own direction. The superior oblique pulls the eye to look down and laterally and the inferior oblique pull the eye to look um and medialy.
How many muscles in one eye?
Orbital muscles of the eye include: Superior Oblique Inferior Oblique Superior rectus inferior rectus lateral rectus medial rectus Levator Palpebrae superioris (controls eyelid) So 17 muscles control the movement of the eyeball.
Name Four muscles of the eye?
You can choose four of the six: Superior rectus, Inferior rectus, Medical rectus, Lateral rectus, Superior Oblique and Inferior Oblique.
