Important structures :

1.Nucleus of oocyte (primary ovarian follicle)
2.Follicular epithelium (primary ovarian follicle)

Die Abbildung zeigt einen Primärfollikel im Rindenstroma eines Ovars. Das die Oozyte umgebende Follikelepithel ist ein einschichtiges kubisches Epithel. Die Zona pellucida (Glashaut) zwischen der Zellmembran der Oozyte und dem Follikelepithel ist gut erkennbar, ebenso die bindegewebige Hüllschicht um den Primärfollikel.

Azan (Heidenhain)

Azan dye is a multiple or trichromatic staining method. It differentiates extracellular connective-tissue fibres, tissues, and cell components.

Structures Colour
Nuclei red
Cytoplasm reddish
Connective-tissue fibres
- Collagenic
- Reticular
- Elastic

blue

unstained or reddish
Muscle tissue red-orange

Dyes:

Azokarmin Azokarmin is a red dye used mainly to stain cell nuclei.
Aniline blue-
orange G
This dye is used for counterstaining.

HistoNet2000 - Help

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!
