Hint: The eyes are the visual organs of the body. We use them to see objects around us. The eyes move in various directions in order to focus on an object or a scene perfectly. Their voluntary and involuntary movement occurs due to muscles. These muscles help the eye to move in various directions.
Complete answer:
There are six muscles that are present in the eye orbit, also known as the socket or cavity, that are responsible for the rotation of the eye. They are known as extraocular muscles.
- The muscles are lateral, medial, inferior, and superior rectus muscles that move the eye outwards, inwards, downwards, and upwards, and the inferior and superior oblique muscles that help in adjusting the movements.
Additional Information: - These muscles form the extraocular anatomy of the eye. The anatomy consists of the extraocular muscles, conjunctiva, lacrimal gland, Tenon’s capsule, sclera, and cornea.
- The nerves that are involved in the movement of the muscles are trochlear, oculomotor, and abducens. The nuclei of these nerves are present on the brain stem.
So, the correct answer is ‘6 muscles’.
Note: The intraocular anatomy of the eye consists of the anterior chamber, iris, pupil, lens, ciliary body, vitreous, retina, photoreceptors, macula, retinal pigment epithelium, choroid, uveal tract, optic nerve, optic chiasm, and visual cortex.
- The involuntary movement of the eye is controlled by the vestibulo-ocular reflex (VOR). It is a reflex that stabilizes the gaze during head movement with eye movement as the vestibular system is activated.
- The weakness of eye muscles is known as ophthalmoplegia.
