title: Fine structure of the neurons of the geniculate ganglion of the cat.
abstract: The geniculate ganglion of adult cat was studied electron microscopically. The results revealed that the neuronal soma displays different cytoplasmic features and the neurons were classified into two types: light cells and dark cells. Light neurons contained individual clumps of Nissl substance distributed randomly throughout the cytoplasm, dark neurons were characterized by densely packed stacks of Nissl substance in the peripheral cytoplasm. The unipolar cell process showed several ultrastructural peculiarities which differ from multipolar nerve cell axons.
