[Pre- and postganglionic pathways conducting central sympathetic chrono- and inotropic effects to the heart of the cat].
In anesthetized cats, the preganglionic input to the stellate ganglion involved Th3 and Th4 white rami. The chronotropic influences to the heart travelled through caudal anastomose whereas inotropic those--through inferior cardiac nerve. Neurons of these nerves are distributed over the ganglion stellate in different sites. The data obtained suggest that the pathways relating central sympathetic influences, are specialized.
