WebbMost preganglionic neurons in the sympathetic nervous system originate in the spinal cord, as illustrated in Figure 2. The axons of these neurons release acetylcholine on postganglionic neurons within sympathetic ganglia (the sympathetic ganglia form a chain that extends alongside the spinal cord). The acetylcholine activates the postganglionic … WebbPostganglionic neurons A ganglion cell body is usually very short and is found either in the ganglion to be supplied or in the organ wall. Functions An autonomic nervous system operates several involuntary reflexes and is controlled by sensory input and motor output.
