1. | Elastic fibres |
Die braunrot angefärbten elastischen Fasern des Stratum papillare und Stratum reticulare der Skrotalhaut liegen eingestreut zwischen den kaum angefärbten kollagenen Bindegewebsfasern sowie den glatten Muskelzellen. An der Grenze zur Epidermis sind die elastischen Fasern dünner und oft senkrecht verlaufend, zur Subcutis hin dagegen dicker und meist parallel zur Oberfläche ausgerichtet.

A special staining technique used to identify elastic fibres. The table below shows the dyes which selectively stain elastic fibres.
Dyes | Colours of Elastic Fibres |
Orcein | red-brown |
Resorcin-fuchsin | blackish-blue to violet |
Aldehydfuchsin | red to violet |
hemalaun |
dye for staining cell nuclei |
nuclear fast red |
used as a counterstain with Weigerts elastica dye |
Die Spezialmethode zur Anfärbung von elastischen Fasern ist die Elastika-Färbung nach Weigert. Farbstoffe sind Orcein oder Resorcinfuchsin - Kernechtrot. Die elastischen Fasern werden dabei braunrot bzw. schwarzblauviolett angefärbt, während retikuläre und kollagene Fasern, Muskelgewebe, Knorpel, sowie das Zytoplasma der Zellen nicht angefärbt werden.

1. Organization of the screen surface
Right side: histologic specimen
Left side: information about the specimen (above) and general program functions (below)
2.Histologic specimen
Pull the mouse across the histologic specimen for training purposes. A small square with exclamation marks (dynamic labels) will appear where there is an important structure. You should then decide what structure this could be. To check your result, simply click the appropriate square, and the correct label will appear. The option “marked” allows you to see all labels for all structures simultaneously. These can be removed by clicking “unmarked”. This reactivates the dynamic labels.
3. Complementary information
Info: general information about the specimen, as well as a list of the dynamic labels
Drawing: schematic drawing of the specimen
Staining: information about the staining method for this specimen
Knowledge: short texts with basic histologic information, presently deactivated
4. General Program Functions
Home: returns you to the “start” page
Tutor: how to contact the HistoNet Team
Help: Instructions for Use appear
Exit: closes down the HistoNet program
Boxes: goes back to the other specimen of a topic
VM: provides virtual microscopy
