Q.Trace the path of a ray of light from its entry into the eye to the formation of an image on the retina, naming every structure it passes through.

[!TLDR] Light path: cornea → aqueous humour → pupil → lens → vitreous humour → retina, forming a real, inverted image that is converted to nerve impulses and sent via the optic nerve to the visual cortex. [!ANSWER] Cornea → aqueou …

A ray of light entering the eye first passes through the transparent cornea, which contributes most of the eye's total refractive (light-bending) power, then through the watery aqueous humour filling the anterior chamber, then through the pupil, whose diameter the iris has adjusted according to the ambient light level, then through the lens, which makes the fine adjustment of focus through accommodation, then through the gel-like vitreous humour filling the posterior chamber, and finally strikes the retina, where it forms a real, inverted image. The photoreceptors of the retina convert this image into nerve impul …

List every structure in strict anatomical order from the front of the eye to the retina, then c …

Do not omit the aqueous and vitreous humours — both fluids are genuine structures the light passes through, not empty spa …
