[Features of the motor innervation of striated muscle tissue of the esophagus].
By means of neurohistological, histochemical and ultramicroscopical techniques it has been revealed that motor innervation of the oesophageal striated muscle tissue in rats and rabbits is performed by amyelinated nervous fibers, that terminate as nervous-muscle synapses. Ultrastructural peculiarities of these synapses are presented as a large amount of synaptic vesicles in the axonal terminal, as a poor ramification of secondary synaptic folds, as a considerable amount of mitochondria in the adjoining sarcoplasm. Reaction to acetylcholinesterase demonstrates that most of the motor nervous terminals belong to the racemose type. They are situated in the oesophageal musculature chaotically and have less area than synapses of the muscle of the locomotor apparatus.
