Abstract

In order to study of muscle fiber proportion of masticatory muscle, 6 rabbits masticatory muscles (masseter, temporal, internal pterygoid, external pterygoid) were excised. Muscle specimens were fixed in 10% neutral buffered formalin fixer and sectioned $5{\mu}$ for PAS staining. With the light microscopic photograph the proportion of muscle fibers of each muscle were computed. The results were as follow; 1. Average classical red fiber proportion of rabbit masticatory muscles was 85.7% 2. Masseter muscle revealed 90.3% of classical red fiber in the rabbit masticatory muscles.
