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 5μ for PAS staining. With the light microscopic photograph the proportion of muscle fibers of each muscle 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.
