Skeletal striated muscle

Abstract

Skeletal striated muscle exhibits a well-defined structural organization, observable through Masson staining at 10x magnification. In longitudinal sections, parallel muscle fibers are seen, joined by endomysium composed of collagen, stained blue. In transverse sections, muscle fascicles are surrounded by blue-stained connective tissue, which corresponds to the epimysium (surrounding groups of fascicles), perimysium (around a single fascicle), and endomysium (around individual myocytes). This arrangement highlights the anatomical and functional complexity of skeletal muscle tissue.
