Anatomy of the eyeball. The eyeball consists of three layers. Fibrous vascular pigmented and nervous retina. Functionally the most important layer is the retina which receives the external visual stimuli.

The posterior pole of the eyeball is connected with the optic nerve CN II which conveys the information from the retina to the brain. 1 Anatomy of the Eyeball The central points on maximum convexities of the anterior and posterior curvatures of the eyeball are called anterior and posterior poles Fig. The axis of the.

Eyeball spheroidal structure containing sense receptors for vision found in all vertebrates and constructed much like a simple camera. The eyeball houses the retina an extremely metabolically active layer of nerve tissue made up of millions of light receptors photoreceptorsand all of the structures needed to focus light onto it. ANATOMY OF THE EYE AND ITS FUNCTION Vision is wonderful but you could lose it if you have diabetes.

The main parts of the eye Macula Retina Iris Lens Pupil Cornea Iris Vitreous gel Optic nerve. The eyeball consists of three layers. The top layer is the fibrous layer consisting of the sclera and cornea.

The middle layer is the vascular pigmented layer also called the uvea. It consists of the choroid ciliary body and iris. The last layer is the retina or the nervous layer.

These muscles move the eye up and down 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.

Anatomy of the eye. The eyeball is filled with vitreous humor with the aqueous humor lying in the small anterior chamber of the eye. The eye itself is coated with three layers.

The sclera and cornea opaque and transparent layer respectively the choroid filled with blood vessels. The eyeball has three layers surrounding the vitreous body. The fibrous layer the vascular pigmented layer and the nervous layer.

The fibrous layer or the outer layer consists of the sclera and cornea. The sclera is a white outer layer that surrounds the posterior 56 of the eyeball. The sclera can also be divided into three layers.

The episclera the scleral stroma and the lamina fusca. 3D video anatomy tutorial on the anatomy of the eyeball. In this video the following structures are discussed.

The anatomy of the eyeball in humans includes a round pupil though the pupil may be square or elliptical in other animals. The iris lens retina and cornea are just a few parts of this complicated organ.

Once light enters the eye it forms an upside-down image on the back of the interior of the eyeball the retina. Anatomy of the Eye. The sclera is outermost layer of the eyeball.

It is the white and opaque part of the eyeball. Muscles responsible for moving the eyeball are attached to the eyeball at the sclera. At the front of the eyeball the sclera becomes the cornea.

The cornea is the transparent dome-shaped part of the eyeball. To keep this shape the eyeball needs a solid structure. The fibrous layer which is made of dense connective tissue and forms the skeleton of the eyeball.

This layer has two parts. The one that makes the outer layer of the smaller sphere called the cornea. And the one that makes the outer layer of the bigger sphere called the sclera.

Anatomy and physiology. Outer eye Eyelids protect the eyeball and distribute tears across the cornea closure by contraction of orbicularis ocuii muscle facial nerve opening by levator muscle oculomotor nerve lid margin comprises a row of lashes in front of a row of meibomian gland orifices separated by the grey line. 1132 Eyeball Anatomy Premium High Res Photos.

Structure Parts Eyeball Each eyeball is a cystic structure kept distended by the pressure inside it. Although generally referred to as a globe the eyeball is not a sphere but an ablate spheroid. The central point on the maximal convexities of the anterior and posterior curvatures of the eyeball is called the anterior.

Each eyeball may be a cystic structure kept distended by the pressure inside it. Although generally mentioned as a globe the eyeball isnt a sphere but an ablate spheroid. The central point on the maximal convexities of the anterior and posterior curvatures of the eyeball is named the anterior and posterior pole respectively.
