title: The continuity of thick filaments between sarcomeres in honey bee flight muscle.
abstract: One of the most frequently discussed problems of insect flight muscle morphology is the structure of the thick filaments, especially at the Z line. Many attempts have been to solve these problems but no unequivocal answers have been given so far. It is well known that physiological specialisation is accompanied by certain anatomical features in the myofibrillar level; the myofibrils have very short I bands in the resting state and the muscle acts under nearly isometric conditions. In this paper, a fresh approach is used to demonstrate the fine structure at the Z line in honey bee flight muscle.
