Studies on sympathetic B and C neurons and patterns of preganglionic innervation

摘要: The sympathetic ganglion of the toad consists two kinds neurons, sB and sC neurons which axons are B C fibers, respectively. receive a monosegmental innervation preganglionic fibers whereas mono- or multisegmental fibers. pre- postganglionic divided into fast (sB neuron) slow (sC conduction system. velocity is proportional to that synaptically connected neuron in systems. In system, faster than relation reversed antidromic orthodromic responses as well electrical membrane properties were analyzed compared with those neurons. both time constant synaptic potential decay was always longer membrane. potentials abolished at levels −10 mv −7 on average, respectively, indicates equilibrium these almost same. changes excitability soma axon after single response long cathodal current compared.
