Unlabeled diagram of the eye. Muscles of the eye are very strong and efficient they work together to move the eyeball in many different directions. They provide animals with vision the ability to receive and process visual detail as well as enabling several photo response functions that are independent of vision.

The cornea is located just in front of the iris which is the colored part of the eye. Click below to download our free unlabeled diagram of the eye. The Uvea Of The Eye.

Lens Of The Eye. The region of the eye between the cornea and the lens that contains aqueous humor. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina.

The sclera protects the eye and serves as an attachment for the extrinsic muscles. The main purpose of the cornea is to help focus light as it enters the eye. Conjunctiva Of The Eye.

Using a sharp scalpel cut through the sclera around the middle of the eye so that one half will have the anterior features of the eye the cornea lens iris and ciliary body and the other half will contain the posterior features most noticeably where the optic nerve is attached to the eye. Sclera cornea and conjunctiva. It converts light into electrical impulses.

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. Select One Anterior Chamber Ciliary Body Cornea Fibrous Tunic Iris Lateral Rectus Muscle Lens Medial Rectus Muscle Optic Disk Optic Nerve. The iris which is the colored part of the eye controls the amount of light that enters the eye.

- using the eye diagram blank below. They offer protection from excessive light or injury and maintain lubrication by distributing tears over the surface of the eyeball. The middle layer of the wall of the eye includes the choroid coat ciliary body and iris.

Some of these are visible from the outside like the iris and the pupil but others would require a cross-section diagram to even see in the first place. Macula Lutea Of The Eye. Take a look at the diagram of the eyeball above.

The anatomy of the eye is fascinating and this quiz game will help you memorize the 12 parts of the eye with ease. Eyes detect light and convert it into electro-chemical impulses in neurons. It consists of following parts.

The central artery and vein runs through the center of the optic nerve. The eye sits in a protective bony socket called the orbit. Central Artery and Vein.

Middle Layer of the Eye. Iris the colored part of the eye it controls the amount of light that enters the eye by changing the size of the pupil lens a crystalline structure located just. Anatomical structure of Eye.

The fluid produced in the eye. Cornea Of The Eye. Located in the retina between the choroid and the retinal pigmented epithelium RPE layer.

It is enclosed within the eye sockets in the skull and is anchored down by muscles within the sockets. 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. Anatomically the eye comprises two components fused into one.

Provides support to the retina and functions as the basement membrane of the RPE layer. Our Label the Eye worksheet covers all of these and more. Choroid Of The Eye.

Our eyes are highly specialized organs that take in the light reflected off our surroundings and transform it into electrical impulses to send to the brain.

Behind the eye your optic nerve carries. The human eye is a roughly spherical organ responsible for perceiving visual stimuli. Here is a tour of the eye starting from the outside going in through the front and working to the back.

In higher organisms the eye is a complex optical system which collects light from the surrounding environment regulates its intensity through a diaphragm focuses it through an adjustable assembly of lenses to form. Here you can see all of the main structures in this area. Ciliary body choroid and iris.

People have three types of cones L cones that sense long wavelengths reds yellows M cones that sense medium wavelengths greens and S cones that sense medium wavelengths violets blues.
