The retina contains light-sensitive receptor cells; the optic nerve carries impulses to the brain; the sclera is a tough outer layer with a transparent cornea at the front; the iris controls pupil size; ciliary muscles and suspensory ligaments change the lens shape for focusing light; accommodation is the process of changing the lens shape to focus on near/far objects.
La retina del ojo contiene células receptoras sensibles a la luz; el nervio óptico transmite impulsos al cerebro; la esclerótica es una capa externa resistente con una córnea transparente en la parte frontal; el iris regula el tamaño de la pupila; los músculos ciliares y los ligamentos suspensorios cambian la forma del cristalino para enfocar la luz; la acomodación es el proceso de enfocar objetos cercanos o lejanos cambiando la forma del cristalino.
| Front | The eye: retina: optic nerve: sclera: iris: cilary muscles and suspensory ligaments: accommodation: |
|---|---|
| Back | -retina contains receptor cells sensitive to light -optic nerve carries impulses from retina to the brain -sclera is a tough outer layer which has a cornea the front (transparent) -iris controls the size of the pupil therefore amount of light reaching the retina -they change the shape of the lens in order to focus light into the retina -accommodation is the process of changing the shape of the lens to focus on things far/close. |
