Histomorphometric, histochemical, comparative study of skeletal muscle in male and female albino rat

Abstract

Histomorphological and histochemical study, by light microscopy, was undertaken on the skeletal muscle of the albino rat different sex (male and female). The body weight and muscle (biceps barchii in arm and biceps feomris in thigh), were weighted, measured and stained with Hematoxylin and eosin, Masson's Trichrome stain. The results revealed there's significant differences in weight of body, weight of skeletal muscle (biceps barchii in arm and biceps feomris in thigh), and diameter of muscle bundle, was increased in male rat to the female and there is significant difference between them . By the other hand the results of number of muscle fiber measuring of skeletal muscle in both sexes showed no significant changes.
