Glycogen in the neurohypophysis of toads

Summary

Studies with the electron microscope revealed the presence of glycogen granules in the neurohypophysis of toads (Bufo arenarum Hensel). The glycogen appeared as scattered particles or as clusters formed by these particles within the nerve fibers. The scattered granules were intermingled with the neurosecretory granules and with the microvesicles. Chemical assays showed the presence of glycogen in the neurointermediate lobe of the toad's hypophysis.
