Specimen Nr. 03D

Specimen:

Adrenal gland (Suprarenal gland) (Human being)

Staining:

Hopa

Magnification:

50x

Important structures :

1.Cortex of adrenal gland
2.Zone fasciculata of adrenal cortex
3.Zona reticularis of adrenal cortex
4.Chromaffin cells in medulla of adrenal (suprarenal) gland
5.Capillary
Von der Nebennierenrinde sind der untere Abschnitt der senkrecht ausgerichteten Zellsäulen der Zona fasciculata und die an das Nebennierenmark grenzende Zona reticularis zu erkennen. Mark und Rinde sind sehr gut vaskularisiert: um die Zellen sind zahlreiche Kapillaren zu sehen.

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.

Das Nebenrindenmark sezerniert die Katecholamine Adrenalin und Noradrenalin.

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!
