The reflex regulation of the activity of the heart in fishes

Communication I. Reflex action on the heart from stimulation of the afferent fibers of the mesentery and intestine

  • Physiology
  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Summary

The author studied the reflex control of the fish heart which has only one path of effector innervation, viz., the vagus nerves. Literature and personal data show that inhibitory tone in the heart is absent in fish. In stimulating intestinal receptors there appears, depending upon the strength of the afferent stimulation, inhibition or accleration of the cardiac activity.

Hence both effects may be considered as the result of an active impulse of the vagus nerve on the heart.
