Abstract

Morphometrical, histochemical and ultrastructural characteristics of rhea muscles were investigated in limb M. Gastrocnemius pars interna and M. Iliofiburalis. The fibres were larger and the extracellular area was superior in GN than in IF muscle, which presented maximum average diameter of 55 µm. Only one type of fibre was found in rhea muscles. Limb muscles were acid-labile and alkali-stable to m-ATPase, presented moderate to high SDH activity and high glycogen content. The ultrastructural observation of rhea myofibrils showed contracted and stretched areas, as well as abundant glycogen and numerous mitochondria, mainly in IF muscle.
