Description
Abstract
Autonomic ganglia are relays in the
distribution of nerve fibres in the peripheral nervous
system. In the pelvis there are local ganglion formations
in the pathway of nerve fibres to and from pelvic viscera
and vasculature: in rodents these are the male anterior
major pelvic ganglion and the female paracervical
ganglion (Frankenhauser's ganglion). They are unusual
in that they contain both sympathetic and parasympathetic
ganglion cells. Homologous formations
occur in humans. Since the best studied examples
of these ganglionic formations are rodent ganglia the
latter are reviewed in terms of their gross anatomy,
cell morphology and immunohistochemistry. The
synaptology, and neurotransmitter and neuropeptide
contents of the neurona1 perikarya and nerve terminals,
of the ganglia are discussed in relation to the concepts of
coexistence and chemical coding in autonomic ganglia
in general. The neuropeptide content of the nerve fibres
projecting to their visceral targets is described and
discussed in functional terms. Conclusions are drawn
with respect to the contributions made by study of these
ganglia to further understanding of the organisation of
the autonomic nervous system in general. The possible
link between the autonomic nervous system and the
endocrine system is discussed with respect to control of
pelvic visceral activities.
