Putative neurosecretory cells of the cestode Hymenolepis microstoma.
Putative neurosecretory cells were observed with the electron microscope in the nerve cords of the neck region of Hymenolepis microstoma. The cells show evidence of glandular activity by the large numbers of dense-core vesicles produced by the Golgi apparatus. The axons contain synaptoidlike structures with surrounding clouds of vesicles; features analogous to known neurosecretory release sites.
