The cardiac ganglion, which includes nine neurons, attaches into the dorsal wall of the guts. The get more info anterior neurons innervate the guts, Whilst one other posterior neurons make synaptic contact with Those people anterior neurons. The posterior neuron functions given that the pacemaker but additionally capabilities as being the cellular oscillator as well as central sample generator. This posterior neuron produces a prepare of impulses, which excites the opposite posterior neurons.
