Photographic reconstruction of a tongue section stained with
the Azan technique and observed with the objective of 10x.
In the superior part of the microphotography is located the
epithelium
that covers the gustative papillae (with form of leaf),
containing numerous
gustative corpuscles.
The
excretory conduits
of the
Von Ebner´s glands
end in the zone separating the papillae. Underneath the
epithelium is placed a blue-stained
lamina propria,
formed by conjunctive tissue. Below it are observed bundles
of
striated muscle fibers,
arranged transversely and
longitudinally,
and separated by
conjunctive tissue
septa. Details of these structures are observed at higher
magnification in other microphotographies (framed zones red,
green, yellow, and blue)
