This investigation was carried out on retractor bulbi, lateral and medial rectus muscles of six adult dogs. Tissues were collected from near the center of individual muscle bellies. These were stained for m-ATPase at varying pHs during preincubation, NADH-TR, Alpha-GPDH, Modified Mason trichrome and Hematoxyline and Eosin. Muscle fibers were classified as type I and type II, based on their reaction for m-ATPase. The retractor bulbi muscle was composed entirely of type II, oxidative, muscle fibers, with no glycolytic fibers. The rectus muscles presented a stratified composition, with superficial muscle fiber bundles containing a mixture of type II fibers oxidative and glycolytic, and central bundles of type I, mixed with type II. It was observed that there was less interstitial tissue in the center of the muscle bellies. Large diameter nerve fibers were also observed in the central layers.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D018482	Muscle, Skeletal	A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.
