[Ultrastructure of nerve endings of varying function in the wall of the frog urinary bladder].
Sensory and effector nerve endings were presented at ultrastructural level. Four morphological types of receptor terminals were identified that vary in peculiarities of neurilemma, organelle composition, matrix structure etc. These types were suggested to be ultrastructural equivalents for different functional states. Several types of myoneural and neuro-neural synapses and their morphological peculiarities were described. The endings explored are a part of apparatus of nervous regulation of complicated and variable functions of an organ with relatively simple structure.
