Specific Point Wide Area
Note:
1) Some cases have photos taken from more than one slide. They may differ a little bit.
2) Not all the features “written in the practical sheet” are shown in the slides, but only the ones important and the ones that I could see. (the best I can do)
1,2,3,..etcNumbers are used in identifying the needed histological layers.
Zooming“higher magnification”
Inflammatory cells:
1)Lymphocyte
2)Neutrophil
3)Monocyte (macrophage)
4)Eosinophil
Fibrobast regenerates collagen.
When macrophages unite together the form multinucleated “Giant cells”.
