[Catecholamine-containing sympathetic spinal neurons innervating the feline heart].

The present study determined that a population "nonclassical" sympathetic neurons in cats spinal cord contains catecholamines. They are localized in the central, dorsomedial, and lateral regions of the ventral horn of T1-T5 segments of the spinal cord. Electrophysiological study indicated that axonal conduction velocity is 7.3 +/- 0.5 m/s (ranging from 3.6 to 17.2 m/s). Possible functional roles of catecholamine-containing neurons of spinal cord include involvement in sympathetic control of cardiac cycle duration.

[Localization of neurons, making projections via the postganglionic nerves of the stellate ganglion].

Distribution of neurons, forming cardiac nerves of the cat stellate ganglion, has been investigated. The inferior cardiac nerve conducts inotropic influences to the heart. It is formed by the neurons localized in the caudal part of the ganglion. The caudal anastomosis conducts chronotropic influences to the heart. It is formed by the neurons localized in the inferior part of the ganglion and the ventral horn of the spinal nucleus and nucleus intercalatus. Axons of the preganglionic neurons pass through the ganglion and are not interrupted.
