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.

∙ 13y agoSix Extrinsic eye muscles attached to the exterior surface of each eyeball control eye movement and make it possible for the eye to follow a moving object.
Summary of actions of each extrinsic eye muscle:
Lateral rectus- moves eye laterally
Medial rectus- moves eye medially
Superior rectus- Elevates eye and turns it medially
Inferior rectus- Depresses the eye and turns it medially
Inferior oblique- Elevates eye and turns it laterally
Superior oblique- Depresses eye and turns it laterally

What control the movement of these muscle?
YOU!
What is the difference between the voluntary and the involuntary muscle movement?
A voluntary muscle performs movement on command. Involuntary muscle performs with out conscious command.
Would the ratio of motor neurons to muscle fibers be the greatest at the muscle that control the eye?
Yes, th ration of motor neurons to muscle fibers are greatest for the muscles that control eye.
What is the function of the eye-movement muscle?
makes the eye move in circles,up,down,left,and right
What nerves control movement?
the neuron that controls our eye movement and it ism important
What are the symptoms of a hemifacial spasm?
There are many symptoms of a hemifacial spasm. They include muscle movement in the patient's eyelid and around the eye. The muscle movement can vary in intensity.
What type of tissue is the skeletal muscle?
Skeletal muscle is a striated muscle used to control movement of specific body parts
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.
What is the name of muscle hormone control for peristalsis movement?
the prinamial jiction
What muscles control movement of the eyeball?
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 oblique and inferior oblique. There are two muscles that affect the iris (color of the eye), they are the iris sphincter and iris dilator muscles. There is one more muscle inside the eye called the cilliary muscle which is responsible for changing the shape of the lens of the eye and allows a change in focus from distance to near.
What is the Muscle that is predominantly responsible for a movement?
The muscle type responsible for body movements is skeletal muscle. This type of muscle is under voluntary control (unlike cardiac and smooth muscle) meaning that we can consciously control the movements we make. The specific skeletal muscle responsible for movement will depend on what movement is being made.
What is intrinsic eye muscle?
There are many muscles in the eye that control it. The four major muscles are the superior and inferior rectus (control up and down movement) and the lateral and medial rectus (control outer and inner movement). There are also two minor muscles, namely the inferior oblique (controls motion up and out or "extorsion") and superior oblique (controls motion down and in or "intorsion"). In additional to muscle which control movement, the lens of the eye is attached to a muscle called the ciliary body which controls anatomic movements and shape/focusing power of the lens. As we get older, this process of focusing, or accommodation gets weaker and most adults over 40 require reading glasses (magnifiers). Finally, the iris or colored part of the eye is a muscle which can contract and expand and control the amount of light which enters the eye in various illuminated environments.
