Anatomy, Eye

Anatomic Model Of The Human Right Eye Lateral View. The Eyeball Is Composed Of An Outer Fibrous Coat, Consisting Of The Sclera A White Opaque Tunic And, In Front, The Cornea, A Transparent Membrane Allowing To Focus The Image. The Middle Vascular Tunique, The Uvea, Consists Anteriorly Of The Ciliary Body In Incarnate, Muscle Governing The Shape Of The Lens, And The Iris In Blue, A Group Of Muscles Controling The Opening Of The Pupil Black Aperture. The Retina In Purple Covers The Inner Wall Of The Eyeball; Its Vascularization Can Be Investigated By An Ophtalmoscope. The Crystalline Lens, Organ Similar To An Optic Lens, Lies Behind The Iris; It Is Retained In Position By A Ligament, The Zonule Of Zinn Folded Area. The Lens Divides The Eyeball Into An Anterior Segment Anterior Chamber Between The Cornea And The Iris, Posterior Chamber Between The Iris And The Lens And A Posterior Segment, Called The Vitreous Space. The Latter Is Filled With A Gelatinous Substance, The Vitreous Body. The Inferior Rectus Muscle In Red Allow To Lower The Look. The Various Extraocular Muscles Are Posteriorly Bound Together To A Tendinous Ring, The Common Annular Tendon In Gray. It Also Receives The Optic Nerve In White, Transmitting The Visual Data To The Brain, In Which Penetrate The Central Artery In Red And Vein In Blue Of The Retina. (Photo By BSIP/UIG Via Getty Images)
