These colours can be derived from pigments, or, as in the Bali starling, structural colour, caused by light scattering off parallel collagen fibres.
12.
The most common application is to stain muscle fibres red and collagen fibres green or blue, Masson's trichrome being the most commonly used method.
13.
In addition, liver biopsies may have fine collagen fibres between the liver cells, and the amount of collagen may be estimated based on the staining method.
14.
In scars the collagen is arranged in parallel bundles of the collagen fibres whilst healthy scar free tissue has a basket weave structure ( Figure 1 ).
15.
Once a tendon is damaged the tendon will always be weaker, because the collagen fibres tend to line up in random arrangements instead of the stronger linear pattern.
16.
4 ) Fibrous Capsule :-Fibrous Capsule of Radicular Cyst is composed of mainly condensed parallel bundles of collagen fibres peripherally and a loose connective tissue adjacent to epithelial lining.
17.
The submucosa of the colon is composed almost entirely of collagen, both type I and type III . Several layers of collagen fibres make up the submucosa of the human colon.
18.
Arapaima scales have a mineralised, hard, outer layer with a corrugated surface under which lie several layers of collagen fibres in a " Bouligand "-type arrangement.
19.
They are primarily made of an elastic fibre called octopus arterial elastomer, with stiffer collagen fibres recruited at high pressure to help the vessel maintain its shape without over-stretching.
20.
This results in a separation of the collagen fibre by accumulating ground substance eventually the collagen fibres are fragmented and disintegrated and the affected focus takes the appearance and staining characteristics of fibrin.
