General Objective
An introduction to the use of the virtual microscope.
Specific Objective and Learning Activities
To learn the correct use of virtual microscopy using computers and to employ various virtual histological databases for enhancing learning as well as for revision purposes.
In Histology, you are expected to study the features of histological preparations as virtual images, which were scanned from real stained sections, which were mounted on glass slides and listed in the Learning Activities. In these classes you may encounter structures and terminology not defined in lectures. You will need to read about these structures in your textbooks.
Learning Activity
Read sections in your course manual on General Hints on Staining Procedures and Routine Staining Protocols.
Virtual Slides: ANAT2241 The Virtual Microscope
Introduction
Histological sections, which are slices of tissue usually from 5 - 8µm thick (see Dimensions below), can be examined efficiently as follows:
- Use the Slide Catalogue in your course handbook to determine:
- The animal from which the section is taken.
- The stains used (thereby defining the colours of the major tissue components). Note that stains are not examinable.
- Low power sketches or notes made may help you to remember the main histological features of a section, e.g., which major tissue components are present.
- Note the 2-D shapes in the section and the major tissue components present and try to determine the approximate 3-D shape of the whole organ from which the section was taken. Is the section cut randomly through the organ? Is there an obvious lumen in the section?
Abbreviations
- XS - cross section
- TS - transverse section
- LS - longitudinal section
- LM - light microscope or light micrograph
- EM - electron microscope, or electron micrograph
- 2-D = 2-dimensional
- 3-D = 3-dimensional
Dimensions
1mm = 103 micrometres (µm) = 106 nanometres (nm)
A micrometre is often called a "micron" (µm); 1µm = 10-6m
Resolving Powers
- Unaided eye - approx. 0.1 mm = 100µm
- Light microscope - approx. 0.1 µm = 100nm
- Electron microscope - approx. 1 nm
What are Virtual Slides?
High magnification scanned digital images of tissue sections on glass slides acquired using a x40 microscope lens stored in a multi-resolution file format and viewed in a web browser window with software capacity to “click and drag” and “zoom in” on the image, which simulates the examination of glass slides with a real microscope, but with the added benefits of always having optimal focus and contrast, with orientation maintained and avoiding section-to-section variability. This allows all students to examine the same scanned tissue section.
Computer Requirements
- Virtual slides requires a Flash Player (Adobe) plug-in to be installed in the browser application and will not function without this player.
- Flash Player will not function on any Apple iPad (iPad or mini-iPad). It can function on their laptop and desktop computers.
- All practical class computers have this player installed.
- If you are using your own desktop or laptop computer this plug-in may need to be installed before virtual slides will display.
- Ensure that you are downloading and installing the latest player version and only from the official Adobe website (http://get.adobe.com/flashplayer).
- Note - you should also be using the latest available browser software.
- If you install this plug-in yourself you may need to shutdown and restart the browser application before it will function.
