1. Anatomy and Connectivity: The sympathetic division of the ANS originates from the thoracolumbar region of the spinal cord, while the parasympathetic division primarily stems from the craniosacral segment. The sympathetic division has short preganglionic fibers, which synapse with postganglionic neurons located in the chain ganglia near the spinal cord. In contrast, the parasympathetic division has long preganglionic fibers that synapse with postganglionic neurons in terminal ganglia close to or within the target organ.

2. Neurotransmitter System: The sympathetic division's preganglionic fibers release acetylcholine, whereas its postganglionic fibers are mainly adrenergic neurons which release norepinephrine. However, some of these fibers release epinephrine when they innervate the adrenal medulla of the adrenal gland. In the parasympathetic division, both preganglionic and postganglionic fibers release acetylcholine.

3. Physiological Effects: The sympathetic division primarily prepares the body for "fight or flight" situations. It generally increases blood pressure and heart rate, and it stimulates the release of epinephrine from the adrenal medulla, further intensifying these effects. In contrast, the parasympathetic division is responsible for "rest and digest" functions, promoting digestion, decreasing blood pressure, and slowing down the heart rate.
