The intention of this book is to offer a comprehensive description and
discussion of autonomic nerve function in the vertebrates from several
points of view. Sections on anatomy, biochemistry of the transmitter
substances and the structure, physiology and pharmacology of the
different types of autonomic neurons have been included, together with
chapters dealing with the autonomic nervous control of some organs and
organ systems in the different vertebrate groups. Although knowledge in
several of these areas is based primarily on studies of mammals, a
certain emphasis has been placed on the autonomic nerve functions in the
non-mammalian vertebrates to describe, from a comparative physiological
point of view, the adaptations and possible "phylogenetic trends" in the
development of the autonomic nerve functions in the vertebrates. It is
very obvious that the literature created by the vigorous research
activities within the fields of autonomic nervous anatomy,
histochemistry, biochemistry, pharmacology and physiology is vast
indeed, and not all aspects of the subject may have received fair
treatment in the present volume. With an analogy from astronomy, it is
hoped that the mass compressed into this book has reached the level of
an energy-emitting neutron star, rather than the black hole which would
be the result of compressing too large a mass.
