A comparative histochemical and
morphometric study in two groups of homologous muscles
from different tetrapods (rat, pigeon, lizard and frog) was
performed. On the basis of their fiber diameters and
oxidative enzyme activities, an initial correlation between
fiber types of al1 animals is observed, although in the lizard
and frog muscles, another fiber type does exists that could
not be demonstrated in higher vertebrates. When more than
one histochemical techniques are used for the identification
of each tetrapod fiber types, the lack of correlation between
them becomes obvious. Thus, different animals groups,
each showing a characteristic muscle metabolic pattern,
could be distinguished.
