Organelles, Inclusions, and Points of Interest

Hello,
   Class topics for January 17 2013 include the visible organelles and cellular inclusions (slides 20, 21, 30, 8, 90, 59, 70, 92).  The number and shape of all of these can be used for identification.

Basophilic is a technical term used by histologists. It describes the microscopic appearance ofcells and tissues, as seen down the microscope, after a histological section has been stained with a basic dye. The most common such dye is haematoxylin.
Basophilic describes the appearance of structures seen in histological sections which take up basic dyes. The structures usually stained are those that contain nucleic acid such as the cell nucleusand ribosomes.


An acidophile (or acidophil, or, as an adjectival form, acidophilic) describes is a term used by histologists to describe a particular staining pattern of cells and tissues when using haematoxylin and eosin stains. Specifically, the name refers to structures which "love" acid, and take it up readily.
It describes the microscopic appearance of cells and tissues, as seen down the microscope, after a histological section has been stained with an acidic dye. The most common such dye is eosin, which stains acidophilic organisms red and is the source of the related term eosinophilic.
