Technical Name for the Human Eye Socket – The Anatomy of the Eye

This article was influenced by people who were searching for the term “Technical Name for the Eye Socket” and in order to answer this question, Macular Degeneration Support dediced to provide some information on the anatomy of the eye as well.

The eye, our gateway to the world.  If you close your eyes and try to visualize what it would be like without seeing, chances are you could sense “blackness”, but for the seeing person, it is difficult to comprehend what it is like not seeing.  Having our eyes in working order and being able to be aware of our surroundings in a visual way is something that many people take for granted.  However, for those who have never had vision, there’s very little that we can do to describe or even give them an understanding of seeing.  It must be terrifying for those individuals diagnosed with an eye disease such as macular degeneration to be faced with the thoughts of gradually losing their vision.

For those who were searching, the technical name for the human eye socket is the orbit.  This is the bony cavity that the eyeball sits in with all its associated muscles, blood vessels and nerves.

On the outside of the eye, you have the eyelid and the eye lashes.  The eyelids protect the eyes from foreign material such as dust and dirt.  Plus, when you blink, the eyelids are responsible for spreading tears produced by the tear ducts over the surface of the eye.  This allows your eyes to remain moist and comfortable.  The eyelashes help filter out foreign matter from the eye as well.

The next part in the anatomy of the eye is the conjunctiva.  This is the thin, clear layer of skin that covers the front of the eye, including the sclera and the eyelids.  This serves the purpose of keeping foreign matter and bacteria from getting behind the eye.

Around the inside of the eye is the ciliary body.

The white part of the eye is called the sclera.  This part of the eye is relatively tough and is what gives the eye its shape.  Connected to the sclera is the six extraocular muscles which move the eye left, right, up, down and diagonally.

When it comes to this part of the eye, you may not even realize that you have it.  The front of the eye is covered by a clear layer at the front and centre of the eye known as the cornea.  This part of the eye helps focus incoming light.  After light passes through the cornea, it has to travel through a clear, watery fluid.  This part of the eye is called the aqueous humor.  As the aqueous humor circulates through the front part of the eye, it maintains pressure within the eye.

The colored part of the eye is known as the iris.  The iris will dilate or expand in certain lighting conditions, making the pupil bigger or smaller.  This will control the amount of light that enters the eye.  On bright days, the iris will change so that the pupil of the eye is very small, preventing large amounts of light from entering the eye.  In the dark, the pupil of the eye enlarges to allow the eye to collect more light.

Light will then pass pass through the pupil of the eye and continue through the lens.  The lens of the eye acts the same as the lens of a camera.  The lens of the eye focus light and has the ability to change shape to allow it to focus on objects nearby or further away.  Once the light passes through the lens it continues to the retina by passing through a clear, jelly-like fluid inside the eye called the vitreous.

The retina is a contained at the back of the eye and it is a composed of a thin, light-sensitive lining.  The lens focuses the light properly on the surface of the retina to produce a clear picture of what is being seen.  The surface of the retina must be flat and smooth in order to work properly.  The retina is nourished by a series of small retinal blood vessels.

At the center of the retina is the macula.  This is the portion of the eye that has a high concentration of photoreceptor cells that converts the light that passes into the eye into nerve signals sent to the brain.  At the very center of the macula is the fovea, which is the area of the eye responsible for a persons sharpest vision.  Macular degeneration damages this portion of the retina thus causing a loss of central vision.  Wet macular degeneration tends to be caused with the choroid, or a layer of blood vessels behind the retina that supplies oxygen and nutrients leak and cause  damage to the macula.

Once the retina converts the light into nerve signals, these are sent through the optic nerve at the back of the eye to the brain.

Here is a complete diagram showing the anatomy of the eye, minus the technical name for the human eye socket – the orbit.
