Summary
The pars intermedia of the pituitary in Bufo arenarum Hensel is innervated by two types of fibers, both coming from the adjacent neurohypophysis: 1. The neurosecretory nerve endings, originating in the neurohypophysis and found along the limit of the pars intermedia with the neurohypophysis. 2. The common nerve endings, which penetrate the pars intermedia as a single bundle from the neurohypophysis and distribute throughout the gland.
The present observations report morphological evidence that in the pars intermedia of the pituitary gland in the toad a double nervous control might be involved.
