What is the bone called around your eye?

The eye socket, or orbit, is the bony cup surrounding your eye. Seven different bones make up the socket. The eye socket contains your eyeball and all the muscles that move it. Also inside the socket are your tear glands, cranial nerves, blood vessels, ligaments, and other nerves.

What part of the skull protects eyes?

Parietal bones form the roof of the cranium and curve down to form the sides of the cranium. Also forming the sides of the cranium are the two temporal bones, located behind the eyes.

How does the body protect the eyes?

Eyes are also protected by tears, which moisten them and clean out dirt, dust, and other irritants that get past the defenses of the eyelashes and eyelids. Tears also help protect against infection. With each blink, our eyelids spread a layer of mucus, oil, and tears over the cornea, which covers the front of the eye.

What is the name of the bony socket housing the eyeball?

The eye socket is also called the orbit.

What is the orbit lined with?

The walls that complete this pyramid are the medial, lateral, roof (superior), and floor (inferior) walls. The bones of the orbit are lined with periosteum called periorbita.

What houses the eyeball?

The sclera, the tough protective outer shell of the eyeball, is composed of dense fibrous tissue that covers four-fifths of the eyeball and provides attachments for the muscles that move the eye.

Why are orbital bones important to the eye?

Orbital bones provide a base within the skull for the eyeball to rest, allowing the eye to move and function properly. This structure is designed to provide strong protection for your eyes in the event of head trauma or injury, though sometimes the bones themselves can sustain a fracture.

Which is part of the eye holds the lens?

Small fibers called zonules are attached to the capsule holding the lens, suspending it from the eye wall. The vitreous cavity lies between the lens and the back of the eye. A jellylike substance called vitreous humor fills the cavity, nourishing the inside of the eye and helping the eye hold its shape.

Which is the most important part of the eyeball?

Other important structures in the eyeball include the iris and the lens. Much of the eyeball is filled with a transparent gel-like material, called the vitreous humour, that helps to maintain the spheroidal shape. Immediately beneath the sclera is an underlying vascular layer, called the uvea, that supplies nutrients to many parts of the eye.

Where are the muscles of the eye located?

These muscles move the eye up and down and side to side, and rotate the eye. The extraocular muscles are attached to the white part of the eye called the sclera. This is a strong layer of tissue that covers nearly the entire surface of the eyeball.
