Specimen Nr. 01A

Specimen:

Tongue (Rabbit)

Staining:

Hopa

Magnification:

13x

Important structures :

1.Foliate papilla
2.Taste buds
3.Striated muscle tissue
4.Lamina propria of mucosa
5.Serous end pieces
6.Excretory duct
Die in Reihen angeordneten Papillae foliatae (Blattpapillen) des Kaninchens bestehen aus zwei oder mehreren parallelen Erhebungen bzw. Einsenkungen. Sie sind durch tiefe Gräben, in die die Ausführungsgänge der serösen Drüsen (von Ebner-Drüsen) einmünden, voneinander getrennt. An den Seitenrändern der Papillae foliatae befinden sich die Geschmacksknospen. Unter dem geschichteten Plattenepithel liegt die Lamina propria mucosae und verschiedene angeschnittene quergestreifte Muskelfaserbündel. Letztere sind durch Bindegewebe voneinander getrennt. Häufig liegen Ansammlungen seröser Drüsenstücke dazwischen.

Myocytes grey-blue to grey-green
Erythrocytes yellow-orange

Dyes:

HOPA = Hemalaun, Orange G, Phosphormolybdenic acid, Aniline blue

Cell nuclei are stained with hemalaun or Weigerts iron-hematoxylin and then counterstained with a dye mixture of orange-phosphormolybden with aniline blue.

Die Zunge ist ein Muskelkörper aus quergestreifter Muskulatur, der von Mundschleimhaut überzogen ist. Die Schleimhaut des Zungenrückens besteht aus geschichtetem Plattenepithel mit Papillen für die Geschmacks- und Berührungsempfindung.

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!
