title: Formaldehyde induced catecholamine fluoroscence in the mouse inferior laryngeal paraganglion.
abstract: The presence of high concentrations of catecholamines is shown in the mouse's inferior laryngeal paraganglion by means of fluorescence histochemistry. In mice, the entire organ is composed of 20 to 25 small, intensely fluorescent cells of oval shape (about 15 mum in diameter). The paraganglion is well provided with capillaries. The identification of catecholamines in the inferior laryngeal paraganglion, originally described as nonchromaffin (parasympathetic) paraganglion, presents additional evidence that all paraganglia store biogenic amines, are related to the sympathetic nervous system, and belong to the APUD cell series.
