Figure 5.
Ultra high resolution CT scanning of a sample from C. olor. (a) A view of the central layer clearly shows oriented fibres. The darker fibres are of higher density than the grey amorphous embedding protein. (b) A close-up shows individual fibres. The fibres measured here are approximately 3 μm in diameter/9.5 μm in circumference. (c) A section through the sample shows three layers. The fibres of the outer layer are end-on. (d) The whole sample is seen, this time from a different viewpoint. The fibres of the central layer are now end-on and differential fibre orientation is confirmed.
