The anatomy of the eyelid may seem complex but if we dissolve its multi-layered structure it is actually quite simple.

Anatomy of the eye not labeled. The middle layer of the wall of the eye includes the choroid coat ciliary body and iris. In this article we shall look at the anatomy of the eyelids their layers vasculature and innervation. It is composed of light sensitive cells known as rods and cones.

These are the fibrous corneoscleral coat the uvea or uveal tract composed of choroid ciliary body and iris and the. The iris is the colored part of the eye that controls the amount of light that enters into the eye. The main purpose of the cornea is to help focus light as it enters the eye.

The cornea is located just in front of the iris which is the colored part of the eye. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye. Choroid Of The Eye.

Eye Anatomy 2 Label the iris pupil lens cornea optic nerve retina vitreous eyelash eyelid eyebrow and tear. Eye Anatomy 1 Label the eye diagram. A light sensitive layer that lines the interior of the eye.

And for a description of common vision problems see Refraction and Refractive Errors. The human eye contains about 125 million rods which are necessary for seeing in dim light. Cornea Of The Eye.

The eyelids are split into upper and lower portions which meet at the medial and lateral canthi of the eye. The opening between the two eyelids is called the palpebral aperture or opening. Our two eyes working together give us stereoscopic vision and depth perception.

The anatomy of the eye includes auxiliary structures such as the bony eye socket and extraocular muscles as well as the structures of the eye itself such as the lens and the retina. The main blood supply of the eye arises from the ophthalmic artery which gives off orbital and optical group branches. The retina is the light-sensitive tissue at the back of the eye.

How the Eye Sees. The White Of The Eye. The eye is made up of three basic layers or coats often known as tunics Fig.

Innervation of the eyeball and surrounding structures is provided by the optic oculomotor trochlear abducens and trigeminal cranial nerves. The pupil is the opening at the center of the iris. The eye is situated in the anterior portion of the orbit closer to the lateral than the medial wall and nearer the roof than the floor.

Cones on the other hand function best in bright light. It is capable of moving and follow the objects along with accommodating to near and far. Select One Anterior Chamber Ciliary Body Cornea Fibrous Tunic Iris Lateral Rectus Muscle Lens Medial Rectus Muscle Optic Disk Optic Nerve Pupil Retina Vascular Tunic Vitreous Nerve.

The optic nerve is the largest sensory nerve of the eye. The part of the eye that connects the choroid to the iris. Six extraocular muscles in the orbit are attached to the eye.

Cornea - The cornea is the clear dome-like structure on the front part of the eyeThe cornea delivers 23 of the refracting power to the eye. The choroid coat in the posterior five-sixths of the globe of the eye is loosely joined to the sclera and is honeycombed with blood vessels which nourish surrounding tissues. The extraocular muscles are attached to the white part of the eye called the sclera.

It carries impulses for sight from the retina to the brain. It is the white and opaque part of the eyeball. The eye sits in a protective bony socket called the orbit.

Structure containing muscle and is located behind the iris which focuses the lens. Human eye specialized sense organ in humans that is capable of receiving visual images which are relayed to the brain. Middle Layer of the Eye.

The eyelids are soft tissue structures that cover and protect the anterior surface of the eyeball. The superior rectus is an extraocular muscle that attaches to the top of the eye. The iris lies in front of the crystalline lens and separates the anterior chamber of the eye ball anything in front of the human lens from the posterior chamber anything behind the human lens.

Muscle - orbital part of the orbicularis oculi muscle. In fact the cornea is so clear that one may not even realize it is there. The sclera is outermost layer of the eyeball.

Pain light sensitivity or a feeling of grit in the eye are the usual symptoms. Anatomy of the Eye. Muscles responsible for moving the eyeball are attached to the eyeball at the sclera.

Aperture Of The Eye. Anatomy of the Eye. The inferior rectus is an extraocular muscle that attaches to the bottom of the eye.

These muscles move the eye up and down side to side and rotate the eye. A scratch on the clear part of the front of your eye called the cornea. In the back of the eye the optic nerve and certain blood vessels pierce the sclera.

Layer containing blood vessels that lines the back of the eye and is located between the retina the inner light-sensitive layer and the sclera the outer white eye wall. It is the most visible part of the eye. Anatomy of the Eye.

The Uvea Of The Eye. It moves the eye upward. It moves the eye downward.

The medial rectus is an extraocular muscle that attaches to the side of the eye near the nose. Conjunctiva - The conjunctiva is a mucus membrane that covers the surface of the eye and the inner part of the eyelids. The eyes also can see in varying light and in colour.

The sclera protects the eye and serves as an attachment for the extrinsic muscles. This is a strong layer of tissue that covers nearly the entire surface of the eyeball. The cornea is the transparent clear layer at the front and center of the eye.
