The level of noradrenaline in terminals and varicosities after the ligation performed in the sympathetic ground-plexus.
It is well-known that the ligation of nerve trunk induces an intensive accumulation of noradrenaline proximally to the ligation. A similar ligation, performed in the sympathetic ground-plexus, induces no changes in the segments of terminal fibres situated proximally.
