Introduction Flashcards
1
Q
Basophilic
A
A tissue/structure that has affinity to a basic dye (hematoxylin)
2
Q
acidophilic
A
A tissue/structure that has affinity to an acidic dye (eosin)
AKA Eosinophilic
3
Q
Periodic-acid Schiff (PAS)
A
stains molecules rich in carbohydrates (glycoproteins, proteoglycans)
4
Q
Silver stains
A
for reticular fibers, nerve cell processes
5
Q
Masson’s trichrome
A
three-colored stain that distinguishes cells from their surrounding extracellular matrix
6
Q
Metachromasia
A
change in dye color within a cell/tissue due to interaction between basic dye (e.g. toluidine blue) and polyanions
7
Q
Ground section
A
Bone
Mineralized tissues require specialized techniques for microscopic viewing
- no organic tissue
- air spaces (formerly organic) are dark
- fine detail visible
8
Q
Demineralized Bone Section
A
- no mineralized tissue
- stains well with H&E
- fine detail less visible
