[Development of heart innervation in Xenopux tadpole and relationship with organ function].
Cardial innervation is studied through specific techniques. It is set up in 9 to 18 mm tadpoles. The rhythm of the aneural heart progressively increases. The initial automatic working is of ventricular type. The ventricular action potential acquires its typical form after the establishment of innervation. At the same time, cardial rhythm settles down at 110 beatings/minute.
