Medical histology applies microscopy to the human body, seeking to discover. Thinking in histology runs along these lines. How does one prepare. What kinds of microscopy can be applied? How does one. analyse and describe the images yielded at different orders of magnification. Does the microscopic appearance of the tissue or. What experiments can one do to test ideas on how structure. The answers comprise a large body of knowledge graced in several ways. First. histology is colourful. Secondly, almost everything seen is actually there. Third, one handles and. Fourth, the structures can be interpreted. So much is now known of the roles of cells and. Powerpoint.

Observation and recording by means of the microscope, and. A drawback to using our eyes. Memory is unreliable. C MICROSCOPY1 Microscopy in general. The main distinction is between light microscopy and electron microscopy. The usual light microscope uses a visible light source with a system of. The image of this object is then magnified by two sets of lenses, the. Total magnification is then the product of these. X 1. 0 = 4. 00. The resolution or resolving power - how. This limit to resolution is determined mostly by the wavelength of the light. The only way to improve resolving power is to reduce substantially the. This is achieved by the electromagnetic beam of the. The beam is focused through the object suspended on its. Chapter 3. 0. K). Caution! the link takes you there , but 'back' brings you only to the start of the last. Chapter that you linked to.]The resolutions so far achieved in biology with transmission electron microscopy. TEM/EM) are of the order of 1 nm at a magnification of X 2 0. The other. forms of microscopy - phase- contrast, interference, fluorescence, confocal. X- ray diffraction) - will be discussed in Chapter. Microscopy for the student (may not apply in toto to the. The usual class microscope has eyepieces/oculars magnifying X 1. X 4, X 1. 0, X 4. X 9. 5 (oil immersion) lenses. Normally the three lower- power lenses are kept mounted on the nosepiece. Every time it is used, the microscope should be set up to the best. How to do this is described briefly below. Keep in mind the limit to resolution. In practical terms. The section has some thickness, so that the fine- focusing. Essentially, though, we are getting a. For what the structure looked like in the third dimension, the. Artefacts (appearances not due to the original nature of. Gross examples arise from: (l) clumsy excision from. Setting up the microscope(a) Ask for and read the instruction booklet for the 'scope.(b) Familarize yourself with the parts and controls of the microscope, in. Before plugging in the microscope, check to feel how the switch and. Plug in, switch on, and adjust the rheostat up one third of its. Otherwise, use artificial light provided by an electric bulb behind a. Light intensity. can be increased by bringing the lamp nearer to the mirror, if the lamp is not. If the condenser in use (nearly always), use the plane side of the mirror. Raise the condenser to very near the underside of the. Place a clean, stained slide on the stage and using the coarse and fine. X l. 0 objective.(h) With the condenser racking knob focus the light source on the specimen. This has happened when the specimen itself is in focus and some aspects of the. If this feature of the light source is. Do not. lower the condenser way out of focus as a means to reduce the light intensity.(i) The iris diaphragm should now be closed just to the point where glare is. Further closure will make the field too dark and reduce resolving. The microscope is now set up for use, but the requirements change for each. Higher power objectives require more light thus the iris will need. Note that the objective lenses are of different lengths, and they are not. Be careful when switching in a higher power lens that it. Clean the lenses only with. If the X 4. 4 objective will not focus to a clear image, check first that. Use of the 'oil immersion' lens..
