Abstract

  • 1.

    1. Localization of catecholamines in the lungs of the lizard revealed innervation of the smooth muscle bands by fine fluorescent varicose nerves containing noradrenaline.

  • 2.

    2. Blood vessels in the wall of the lung were surrounded by a dense plexus of fluorescent nerve bundles.

  • 3.

    3. Adrenergic ganglion cells were a rare feature in the lung wall, although there were numbers of ganglion cells containing autofluorescent granules.

  • 4.

    4. Groups of small monoamine-containing cells, often surrounded by fluorescent nerves, were located on the septal muscle of the lung.

  • 5.

    5. These histochemical results are correlated with the physiological and pharmacological properties of the lizard lung.
