It's the string like things on the back of the eye next to the optic nerve, it allows the eye to move around.
Human eye have ciliary muscles not eye muscles,which holds the eye lens in position.these muscles controls the focal length of eye lens.
They change the shape of the lens. (Novanet)
Extrinsic eye muscles move the eyeball in relation to the rest of the body, whereas intrinsic muscles move structures within the eyeball.A: The extrinsic muscles control the movement of the eyes.The extrinsic muscles are controlled by the somatic nervous system(voluntary) The intrinsicmuscles control the lens and pupil. The intrinsiceye muscles, (including the iris sphincter, radial pupilodilator muscles and the ciliarymuscle), are under the control of the autonomic nervous system(involuntary)
extrinsic muscles are strained
The extrinsic muscles of the eye control the movement of the eyeball and enable eye movements, such as looking up, down, and sideways. These muscles work together to coordinate eye movements and allow us to track objects and focus on different points in our visual field.
inferior oblique
The medial rectus muscles are primarily responsible for the convergence reflex. When focusing on a near object, these muscles contract to rotate both eyes inward, allowing them to converge and maintain single binocular vision.
yes they are, I studied this in college
Medial Rectus
eyebrows, eyelids, lacrimal apparatus, conjunctiva, and extrinsic eye muscles
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.
