Myotendinous junction in the dorsal parts of pereonites of premolt adult Ligia italica is an extensive anchoring junction. The entire zigzag folded basal and apical membranes of tendon and muscle cells, respectively, are engaged in this outstanding intercellular mechanical connection (3A). Prominent electron dense cytoplasmic plaques are evident along both cell membranes, separated by a thin layer of extracellular matrix (3B). MC muscle cell TC tendon cell.
