part: conjunctiva a transparent membrane covering the eyeball and under surface of the eyelid
part: eyeball the ball-shaped capsule containing the vertebrate eye
part: ocular_muscle__eye_muscle__eyemuscle one of the small muscles of the eye that serve to rotate the eyeball
part: cornea transparent anterior portion of the outer covering of the eye; it covers the lens and iris and is continuous with the sclera
part: uvea the part of the eye that contains the iris and ciliary body and choroid
part: iris muscular diaphragm that controls the size of the pupil; it forms the colored portion of the eye
part: pupil contractile aperture in the iris of the eye
part: crystalline_lens__lens biconvex transparent body situated behind the iris in the eye; it focuses light waves on the retina
part: lens_capsule a tenuous mesoblastic membrane surrounding the lens
part: central_artery_of_the_retina__arteria_centralis_retinae__arteriacentralisretinae a branch of the ophthalmic artery; enters the eyeball with the optic nerve
part: ciliary_artery__ciliaryartery__arteria_ciliaris one of several arteries supplying the choroid coat of the eye
part: lacrimal_artery__arteria_lacrimalis an artery that originates from the ophthalmic artery and supplies the lacrimal gland and rectal eye muscles and the upper eyelid and the forehead
part: lacrimal_vein__vena_lacrimalis drains the lacrimal gland; empties into the superior ophthalmic vein
part: lacrimal_apparatus the structures that secrete and drain tears from the eye
part: lacrimal_gland__lachrymal_gland__lachrymalgland__tear_gland any of the glands in the eyes that secrete tears
part: lacrimal_duct__lachrymal_duct__lachrymalduct__tear_duct any of several small ducts that carry tears from the lacrimal glands
part: lacrimal_sac__tear_sac__dacryocyst either of the two dilated ends of the lacrimal ducts at the nasal ends of the eyes that fill with tears secreted by the lacrimal glands
part: retina the light-sensitive membrane covering the back wall of the eyeball; it is continuous with the optic nerve
part: neuroepithelium epithelium associated with special sense organs and containing sensory nerve endings
part: fovea_centralis__foveacentrali__fovea area consisting of a small depression in the retina containing cones and where vision is most acute
part: parafovea area of the retina immediately surrounding the fovea
part: macula_lutea__macula__macular_area__maculararea__yellow_spot a yellowish central area of the retina that is rich in cones
part: visual_cell one of the cells of the retina that is sensitive to light
part: blind_spot__blindspot__optic_disc__opticdisc__optic_disk__opticdisk the point where the optic nerve enters the retina; not sensitive to light
part: retinal_cone__retinalcone__cone__cone_cell visual receptor cell sensitive to color
part: iodopsin a violet photopigment in the retinal cones of the eyes of most vertebrates; plays a role in daylight vision
part: retinal_rod__retinalrod__rod__rodcell visual receptor cell sensitive to dim light
part: visual_purple__rhodopsin__retinal_purple__retinalpurple a red photopigment in the retinal rods of vertebrates; dissociates into retinene by light
part: sclera__sclerotic_coat__scleroticcoat whitish fibrous membrane (albuginea) that with the cornea forms the outer covering of the eyeball
part: pupillary_sphincter__pupillarysphincter__musculus_sphincter_pupillae a ring of smooth muscle surrounding the iris
