Degradation in muscle fibre: connective tissue junctions in the spotted trevalla (Seriolella punctata) examined by scanning electron microscopy

Abstract

The junctions between the muscle fibres and the connective tissues of the myocommata in the spotted trevalla (Seriolella punctata Forster) were investigated by scanning electron microscopy. In prerigor muscle, the fine collagen fibrils which arise from the myocommata to form the muscle cell envelope were evident. After the fish were stored several days in ice, progressive deterioration was observed in these fibrils. The structure and the degradation was similar in nature to that reported previously in blue grenadier
