histology basics Flashcards
whole mounts
when a structure, a tissue fragment, or whole organism are relatively thin and translucent, they may be preserved and mounted on the glass slide intact
sections
extremely thin slices of a specimen mounted on a glass slide
longitudinal section
tissue or organism bone is cut along its length
cross section
a tissue or small organism is cut perpendicular to its length
oblique section
tissue is cut at an angle
smears
tissue smears may be protected from liquid or soft tissues or rubbing tissue across the surface of the glass slide
hematoxylin and Eosin staining
most common staining regimen
hematoxylin
binds to nucleic acids, staining them blue purple
eosin
binds to proteins, staining them red-pink
