[Morphostructure of myoneural synapses of the lingual musculature]

The human and the rabbit tongue with different histologycal techniques are studied. Most muscle fibers of the tongue shown one or various motor end-plates derivated from a single axon. It is not frequent a polisynaptic innervation. The muscular polo of the synapse have few nyofibrils, nucleus and sarcoplasma without differentiation. Does not exit differences between the motor end-plates of the tongue from the man and the rabbit.
