Gastrointestinal motility results from coordinated contractions of the tunica muscularis, the
muscular layers of the alimentary canal. Throughout most of the gastrointestinal tract …

The enteric nervous system is one of the three divisions of the autonomic nervous system,
the others being the sympathetic and parasympathetic. In contrast to the other divisions, it …

Evidence that adenosine triphosphate or a related nucleotide is the transmitter substance
released by non-adrenergic inhibitory Page 1 Br. J. Pharmac. (1970), 40, 668-688. Evidence …

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 …

1) The anatomy of the autonomic nervous system in teleost fish, amphibia, reptiles, and birds
is essentially similar to that seen in mammals. However, a sacral parasympathetic system is …

To explore the involvement of NO in normal peristalsis, the effects of inhibitors of NO
synthase, including N ω-nitro-L-arginine (l-NNA) and N ω-nitro-L-arginine methyl ester (l …

The peristaltic reflex is a fundamental behavior of the gastrointestinal (GI) tract in which
mucosal stimulation activates propulsive contractions. The reflex occurs by stimulation of …

It is now well established that there are intramural inhibitory neurons which are neither
adrenergic nor cholinergic in the gastrointestinal tract of a wide range of vertebrate species …

1. Micro‐electrodes were used to examine transmission from intrinsic and extrinsic nerves to
single cells of the longitudinal and circular muscle coats of colons from guinea‐pigs and …

Mammalian gastrointestinal muscle is supplied by non-adrenergic, intrinsic inhibitory
neurons. The substantial evidence which exists to suggest that adenosine triphosphate is …
