Lens of the eye. False-colour scanning electron micrograph of fibre-like cells that form the lens of the human eye. The transparency of the lens (width 4 millimetres) is due to the absence of nuclei in its cells,& to the crystalline precision of their arrangement. The zip-like rows of ball-&-socket joints that bind these cells together may also play a part. In cross-section lens cells are flattened hexagons,arranged in regular stacks. The cells of the lens are called fibres because of their dimensions,with lengths of 10 millimetres and diameters of 5 micrometres. Magnification: x880 at 6x7cm size | |
