Answer #1

The preganglionic fibres of sympathetic system originates from thoracic and lumbar segments of spinal cord whereas parasympathetic fibres originates from brainstem and sacral segments of spinal cord. The ganglion in parasympathetic system is close to the effector organ which means that preganglionic fibres are long and postganglionic fibres are short, in contrast to this ganglion of sympathetic system is close to CNS, having short preganglionic fibres and long postganglionic fibres.
