Answer #1

1st difference- the preganglionic neuron in sympathetic system is shorter as compared to post ganglionic neuron. Whereas in parasympathetic system, the preganglionic neuron is longer than post ganglionic neuron.

2nd difference- the sympathetic neurons arise from the thoraco lumbar portion of spinal cord (T1 to L3).

Whereas in parasympathetic system, the neurons arise from the cranio sacral portion ( cranial segment 3,7,9,10 and S2-S4).

3rd difference- in sympathetic system, large number of postganglionic fibres are present as compared to parasympathetic system. In parasympathetic system, the postganglionic neurons are less comparatively.

Compare and contrast the sympathetic and parasympathetic divisions of the autonomic nervous system. Include information about pre- and post-ganglionic neurons, the neurotransmitters involved, and the typical response at each of the following effectors: adrenal medulla, arterioles, sweat glands, and the heart.
