The extraocular muscles are not found inside the eye, but rather attach to the eye. These muscles generate the various movements of the eyes, which grant the ability to direct one's gaze. This muscle group is distinct from the muscles inside the eye (the intraocular musculature, including the muscles of the iris that change the size of the pupil).

Muscles vary considerably in their size, location, and specific function. For instance, the muscles in the heart are much bigger than the ones in the eye and have a more vital role as in most cases a person would die if their heart muscle stopped working.

The extraocular muscles control movement of the eye as well as elevation of the upper eyelid. These small muscles are housed within the orbit and are innervated by 3 cranial nerves. Six of them work in unison to allow for medial, lateral, superior, and inferior rotation of the eye. One controls elevation of the upper eyelid.

Extraocular Muscles: The eyeballs in the human skull are capable of moving in various directions. This is because each eyeball contains various muscles called extraocular muscles which are capable of moving them when they contract. Answer and Explanation: 1

The eyes can move voluntarily and involuntarily using a system of of six muscles called the extraocular muscles. These allow for the following eye movements: depression and elevation, abduction and adduction, and extorsion and intorsion. Answer and Explanation:

The evolution of some eye muscles in humans has allowed for more precise and controlled vision. Answer and Explanation: 1 The eye is the sense organ responsible for delivering visual information to the brain, giving it a more clear perspective of its surroundings.

Extraocular Muscles: The extraocular muscles are the muscles attached to the outside of the eye and help control its movement. These muscles consist of the superior oblique muscle, inferior oblique muscle, superior rectus muscle, inferior rectus muscle, lateral rectus muscle, and medial rectus muscle.
