The lens is attached to the ciliary body by ligaments.

Internal parts of the eye. The Choriod is modified to form the Iris and the Ciliary Body at the front of the eye. The space bounded by the lens ciliary body and retina is the largest compartment of the eye and is called the posterior cavity. It is a transparent mucous membrane which covers the internal palpebral surfaces and folds on to the anterior sclera and comea where it is continuous with the comeal epithelium.

The pupil appears as a black dot in the middle of the eye. The eye is connected to the brain and dependent upon the brain to interpret what we see. Six extraocular muscles in the orbit are attached to the eye.

The internal components of an eye are. Located behind the cornea is the pupil the part of the eye through which light can enter the interior of the eye. It is a transparent biconvex lens of an eye.

It is the innermost layer of the eye. The cornea allows light to enter the eye. The lens along with cornea refracts light so that it focuses on the retina.

The lens is attached to the ciliary body by ligaments. The size of the pupil determines the amount of light that enters. The extraocular muscles are attached to the white part of the eye called the sclera.

As light passes through the eye the iris changes shape by expanding and letting more light through or constricting and letting less light through to change pupil size. These layers regenerate very quickly helping the eye to eliminate damage more easily. The transparent structure inside the eye that focuses light rays onto the retina.

These muscles move the eye up and down side to side and rotate the eye. The iris is partly responsible for regulating the amount of light permitted to enter the eye. The eye sits in a protective bony socket called the orbit.

An eyelid is a thin fold of skin that covers and protects the eye. How the Eye Works. There are six extraocular muscles that control eye movements.

It is light sensitive and acts as a film of a camera. They eye is also full of liquid which is under pressure. The pupil is the opening in the centre of the iris that regulates the amount of light entering the eye.

This is a strong layer of. The conjunctiva helps to protect the eye ball and keeps it moist. The colored part of the eye.

The sclera also holds the internal organs of the eye in place so that they can actually function correctly. The lens then changes shape to allow the accurate focusing of light on the retina. The eyes sit in bony cavities called the orbits in the skull.

Eye Structure of the human eye Parts of the human eye The internal structure of the eye Pupil Iris Sclera Eye. The surface of the eye and of the inner eyelids is covered by a clear protective membrane called the conjunctiva. Along with vessels in the underlying choroid coat they supply blood to the cells of the inner layer.

The front visible part of the eye is made up of the whitish sclera a coloured iris and the pupil. This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye. The eye has many parts which work together to accomplish vision and to keep the structures required for vision safe from infection and injury.

The clear gelatinous substance filling the central cavity of the eye. A thin layer called the conjunctiva sits on top of this. The sclera contains this pressure and simultaneously keeps the iris the pupil the retina and the other parts of the eye in position so that the correct focal length is always maintained.

The lens along with cornea refracts light so that it focuses on the retina. The sclera provides structure and safety for the inner workings of the eye but is also flexible so that the eye can move to seek out objects as necessary. It is the innermost layer of the eye.

Depending on the intensity of the light the eye widens or narrows the pupil in order to control the amount of light passing through bright light small pupil dark light large pupil. Eye Parts and Functions. The five senses include sight sound taste hearing and touch.

Sight like the other senses is closely related to other parts of our anatomy. Click the parts of the eye to see a description for each. It is light sensitive and acts as a film of a camera.

The cornea is the clear outer part of the eyes focusing system located at the front of the eye. This black area is actually a hole that takes in light so the eye can focus on the objects in front of it. It is a transparent biconvex lens of an eye.

There are several layers of the cornea creating a tough layer that provides additional protection. The cornea is the outer covering of the eye. Glands of Moll are modified sweat glands at the edge of the eye lid.

Filled with blood capillaries It is rich in blood vessels that bring oxygen and nutrients to nourish the eyeball. Black-pigmented layer under the Sclera that prevents the internal reflection of light rays. Hover the diagram to zoom.
