Specimen Nr. 11


Pyramidal cells, cerebral cortex (Human being)


Golgi silver stain



Important structures :

1.Cortex, layer V
2.Pyramidal cell


Cortex, layer V
Pyramidal cell

Pyramidal cell of cerebrum[bu]

1. Dendrites
2. Axon
3. Cell body

Silver impregnation

In silver impregnation an ammoniacal silver-hydroxide solution is absorbed by tissue structures and precipitated by a reducing agent.

This results in a black stain of:

Cortex, layer V
Pyramidal cell

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!
