Extract

The fine structure of the flame cells, tubules and excretory pore of the miracidium of Fasciola hepatica are described. The tubules are formed from the flattened surfaces of cells rolled round and joined at their tips by a desmosome. Vesicles are present in the wall of the tubule, possibly indicating secretory activity. Clubshaped microvilli are present only in the terminal region near the excretory pore. Possible functions of the system are discussed.
