Die
Abbildung zeigt einen Frontalschnitt durch das mittlere Stockwerk des
Kehlkopfs, Cavitas laryngis intermedia oder Glottis, das zur Hälfte zu
sehen ist. Kranial wird es von der
Taschenfalte (Plica vestibularis), kaudal von der
Stimmfalte (Plica vocalis) begrenzt, seitlich ist der Raum zum
Ventriculus laryngis erweitert.
Hinweis: Zum besseren Verständnis dieses histologischen Schnittes trägt

This is the dye most commonly used to stain connective tissue.
| Structures | Colour |
| Nuclei | black-brown |
| Cytoplasm | yellow-brown |
| Connective-tissue fibres - Collagen - Reticular - Elastic |
red - yellow |
| Muscle tissue | yellow |
| Erythrocytes | yellow |
| Weigerts iron hematoxylin | This dye is one of the hematoxylins, but stains much more intensively than hemalaun. It is used with van Gieson’s dye to stain cell nuclei. |
| Picro-fuchsin or Picro-thiacid mixture | This dye solution simultaneously stains connective tissue red and muscle tissue yellow (simultaneous stain). |

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
We hope you will enjoy working with HistoNet2000 and learn a lot from it!
