Chapter 1: Histology & Its Methods of Study
In preparing tissue for routine light microscopic study, which procedure immediately precedes clearing the specimen with an organic solvent?
Which of the following staining procedures relies on the cationic and anionic properties of the material to be stained?
b. Periodic acid-Schiff reaction
c. Hematoxylin & eosin staining
e. Metal impregnation techniques
In a light microscope used for histology, resolution and magnification of cells are largely dependent on which component?
c. Eyepieces or ocular lenses
e. The control for illumination intensity
Cellular storage deposits of glycogen, a free polysaccharide, could best be detected histologically using what procedure?
d. Hematoxylin & eosin staining
e. Periodic acid-Schiff reaction
Adding heavy metal compounds to the fixative and ultrathin sectioning of the embedded tissue with a glass knife are techniques used for which histological procedure?
a. Scanning electron microscopy
b. Fluorescent microscopy
e. Transmission electron microscopy
Resolution in electron microscopy greatly exceeds that of light microscopy due to which of the following?
a. The wavelength of the electrons in the microscope beam is shorter than that of a beam of light.
b. The lenses of an electron microscope are of greatly improved quality.
c. For electron microscopy the tissue specimen does not require staining.
d. The electron microscope allows much ...
