Skeletal Muscle - Edema

    Narrative
    Skeletal muscle - Edema in a male F344/N rat from a chronic study. Muscle fibers and muscle bundles are separated by expanded interstitial spaces filled with pale pink material.

    Skeletal muscle - Edema in a male F344/N rat from a chronic study (higher magnification of Figure 1). There are separated muscle fibers and muscle bundles due to an accumulation of pale pink interstitial material.

    Skeletal muscle - Edema in a male F344/N rat from a chronic study. A longitudinal section of skeletal muscle shows expansion of the interstitial spaces due to an accumulation of poorly stained edema fluid.
