The caudal neurosecretory system. A critical evaluation of the two-hormone hypothesis
Abstract:
Recent information on the caudal neurosecretory system (urophysis) is collated, with special reference to cellular biology including neural relations, activity and chemistry 8 the biological principles associated with the urophysis, pharmacological analysis of the receptors for these principles, and their possible functions in a physiological sense. The existence of at least two principles, urotensins I and II, is well established. They differ pharmacologically and chemically and may arise from different cell types. At present, osmoregulation, cardiovascular regulation and reproduction are the most likely aspects of organismal physiology wherein these principles may be involved.
