Summary

The functional conditions of cutaneous receptors in the frog's extremity is maintained at the expense of the energy provided by respiratory phosphorylation and glycolysis. As proved by experiments with the registration of the afferent impulsation in the peripheral portion of the sciatic nerve, submersion of the extremity in the ATP solution provokes an increase in the frequency and amplitude of spontaneous impulsation.

Exclusion of respiratory phosphorylation in the skin of extremity by means of 2,4-dinitrophenol, as well as exclusion of glycolysis by monoiodoacetic acid results in the decline of the ATP.

This impulsation is partially restored by amplitude and the frequency of the recorded impulses.

Conversely, exclusion of glycolysis by sodium fluoride, intensifies the impulsation, while lactic acid restores the impulsation to the initial level.
