Ciliary body and iris of the eye
Numéro d’image : 11871880
| False-colour,low-power scanning electron micrograph (SEM) of the human eye,showing the ciliary body & iris. The deeply folded tissue at left & top is the ciliary body,which normally encircles & controls the lens of the eye,flattening it to focus distant objects onto the retina & making it more spherical to focus closer ones. In this view,seen from the back of the eye,the lens has been removed. As a result,one can see through to the less folded muscles of the iris,which control the aperture of the pupil (the black area at bottom right) & so the amount of light that reaches the retina. Magnification: x2.5 at 35mm size. Yellow tint. Reference: MICROCOSMOS,figure 2.9,page 19 | |
