Morphology and histochemistry of primary flight muscles in Rhinolophus mehelyii

S Cebesoy


Two primary flight muscles of Rhinolophus mehelyii were studied using morphological and histochemical analysis. Two fast-twitch fiber types are histochemically identified in pectoralis muscles of R. mehelyii. These were classified as type IIa and type IIb according to glycine-calcium-formalin
preincubation staining protocol for myosin ATPase. The primary flight muscles, serratus ventralis included type I, type IIa and type IIb fibers. Type I fibers were highly oxidative, as stained dark for NADHTR.
Type IIa fibers exhibited relatively weak staining properties for NADH-TR and SDH, indicating an intermediate oxidative capacity. Type IIb fibers showed low oxidative capacity, as indicated by weak reaction for NADH-TR.
