Variable Density of Silver-stained Fibrils in the Myocardium

RECENT investigations 1,2 of the distribution of nerves in human, rabbit and dog hearts have disclosed the presence of delicate, argyrophilic fibrils disposed circularly around myocardial fibres. Hirsch 1 named these fibrils the ‘perimysial plexus’, and suggested that they are the terminal post-gang...

Description
Summary:RECENT investigations 1,2 of the distribution of nerves in human, rabbit and dog hearts have disclosed the presence of delicate, argyrophilic fibrils disposed circularly around myocardial fibres. Hirsch 1 named these fibrils the ‘perimysial plexus’, and suggested that they are the terminal post-ganglionic fibrils of the parasympathetic and sympathetic nervous systems 2 .
