title: The nucleoside phosphatase method as a marker for the recognition of the autochthonous plexuses in blood vessel walls and the possible connection of the latter with acupuncture mechanisms.
abstract: The innervation of the blood vessels of the palatal mucosa of the frog is investigated histochemically. Besides vaso-motor nerves, fibers from the autochthonous plexuses also invest the vessels. Electron microscope studies of the latter show them to be non-nervous in structure contrary to previous belief. It is suggested they may influence vessels in a humoral manner and possibly play a part in acupuncture effector mechanisms. The electron micrographs are considered to reveal structure previously designated "terminal reticulum".
