What are the 6 eye muscles called?
There are seven extraocular muscles – the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. Functionally, they can be divided into two groups: Responsible for eye movement – Recti and oblique muscles.
Do eyes contain muscles?
The human eye has six eye muscles. They are split into two primary groups: the recti muscles and the oblique muscles. The four recti muscles are the lateral rectus, the medial rectus, the inferior rectus, and the superior rectus while the two oblique muscles are the inferior oblique and the superior oblique.
What muscle is found in the eye?
The intraocular muscles include the ciliary muscle, the sphincter pupillae, and the dilator pupillae. [1] The ciliary muscle is a smooth muscle ring that controls accommodation by altering the shape of the lens, as well as controlling the flow of aqueous humor into Schlemm’s canal.
Can you control eye muscles?
Three cranial nerves are responsible for controlling the eye muscles. These are the third cranial nerve (oculomotor nerve), the fourth cranial nerve (trochlear nerve), and the sixth cranial nerve (abducens nerve). The secondary names of these nerves kind of give away what muscles they control.
Which eye muscle is the strongest?
The superior rectus muscle forms its origin on the annulus of Zinn and inserts along the superior edge of the eye.

Do eye muscles weaken with age?
The muscles that squeeze the eyelids shut decrease in strength with age. This decrease in strength, combined with gravity and age-related looseness of the eyelids, sometimes causes the lower eyelid to turn outward from the eyeball. This condition is called ectropion.
What are the muscles of the eye and their functions?
There are six muscles responsible for the different movements of both eyes. They are the lateral, medial, inferior, and superior rectus, and the inferior and superior oblique muscles. Each one of these extraocular muscles has specific functions which allow each eye to move in certain directions.
How many muscles does the human eye have?
Each eye has six muscles that control its movements: the lateral rectus, the medial rectus, the inferior rectus, the superior rectus, the inferior oblique, and the superior oblique.
What are the muscles around the eye?
The orbicularis oculi muscle is a ringlike band of muscle, called a sphincter muscle, that surrounds the eye. It lies in the tissue of the eyelid and causes the eye to close or blink. At the same time, it compresses the nearby tear gland, or lacrimal gland, aiding the flow of tears over the surface of the eye.
What is the function of the eye muscles?
As one of the extraocular muscles, the superior rectus plays an important role in the movement of the eye. The primary function of this muscle is to elevate the eye so that the eyeball moves in an upward direction. The muscle also allows the eye to move in a medial direction, meaning that the eye rotates toward the middle of the body.
