- There are 6 muscles around the eye that are responsible for eye movement. They are called the superior rectus, inferior rectus, lateral rectus, medial rectus, superior obliqu … e and inferior oblique.There are two muscles that affect the iris (color of the eye), they are the iris sphincter and iris dilator muscles.   Extrinsic muscles are voluntary muscles,external to the eye, that control the direction the eye moves in e.g looking left or right.   Intrinsic muscles are wit … hin the eye, such as those that control the size of the pupil.

muscle yoke muscle's Muscles of the two eyes which simultaneously contract to turn the eyes in a given direction. Example: the medial rectus of the right eye and the lateral rectus of the left eye when turning the eyes to the left.oluntary muscles are those controlled by the conscious part of the brain, and are striated. These are the skeletal muscles that enable the body to move, and there are more than 600 of them in the human body. Their fibers are grouped together in sheaths of muscle cells.

Muscles, Nerves, and Blood Vessels in the Human Eye The following muscles help your eyes move around. 1  Levator palpebrae superioris: Originates on the sphenoid bone above the optic canal. It inserts into the superior tarsis and skin of the eyelid. 2  Superior oblique: Originates on the sphenoid bone and inserts into the sclera deep to the superior rectus muscle.

The Extraocular Muscles The movement of either eye into an up/right, up/left, down/right, down/left, up, down, right, or left position of gaze involves the linked and associated contractions and relaxations of multiple eye muscles, of the same eye and of the opposite eye, at the same time.

- Ocular myositis Eye muscle myositis is an idiopathic inflammation of the extraocular muscles in the absence of thyroid disease, ocular myasthenia gravis. A NATOMY: There are six EOMs the medial, lateral, superior and inferior recti, the superior and inferior oblique. ONCLUSION: The six tiny muscles that surround the eye and control its movements are known as the extraocular muscles (EOMs). The primary function of the four rectus muscles is to control the eye's movements from left to right and up and down. The two oblique muscles move the eye rotate the eyes inward and outward.

- Simultaneously, the intrinsic muscles of the eye serve to focus the eye and control the amount of light entering it. Each eye is held in place by three pairs of taut, elastic muscles (extrinsic muscles) that constantly balance the pull of the others.The superior rectus acts to roll the eyeball back and up, but it is opposed by the inferior rectus.imultaneously, the intrinsic muscles of the eye serve to focus the eye and control the amount of light entering it.

The Cranial Nerve Exam The three nerves that control the extraocular muscles are the oculomotor, trochlear, and abducens nerves, which are the third, fourth, and sixth cranial nerves. As the name suggests, the abducens nerve is responsible for abducting the eye, which it controls through contraction of the lateral rectus muscle.

Muscles of the Orbit There are 3 cranial nerves (CN) that control the muscles of the orbit. 1  Oculomotor nerve (CN III): This nerve controls the superior rectus (superior branch), inferior rectus (inferior branch), medial rectus (inferior branch), inferior oblique (inferior branch), and the levator palpebrae superior muscle. The origin is the Annulus of Zinn. 2  Rectus muscles are “straight” muscles. 3  Inferior rectus: In the neutral position, this muscle is responsible for depression, extorsion (outward, rotational movement) and adduction. 4  During adduction, the inferior rectus is responsible for extorsion, adduction and depression.

Anatomy of the Eye Extraocular Muscles: There are six muscles that are present in the orbit (eye socket) that attach to the eye to move it. These muscles work to move the eye up, down, side to side, and rotate the eye. The superior rectus is an extraocular muscle that attaches to the top of the eye. It moves the eye upward.
