The major difference between the ANS and the SNS is that the ANS uses a two-neuron chain to connect the CNS to the effector organ (such as a muscle or gland), while the SNS uses a one-neuron chain. This means that there is an additional synapse in the ANS pathway, which allows for more complex and precise control of organ function. Additionally, the ANS has both afferent and efferent neurons, while the SNS only has efferent neurons.
