The muscle fibers in the origin regions of the triceps muscle of Passer domesticuswere characterized histochemically on the basis of their myofibrillar adenosine triphosphatase (mATPase) activity after acidic and alkaline preincubations. Muscle fibers were identified as type II (alkaline-stable/acid-labile mATPase activity) and type III (alkaline-stable/acid-stable mATPase activity). The number of type II fibers was higher in the muscle studied (83%) and this was found to be significant.
