Answer to Question 1

Answer: The divisions emerge from different levels of the spinal cord (thoracic and lumbar versus cervical/sacral); the sympathetic fibers terminate in ganglia just outside the spinal cord, use different transmitters (ACh for parasympathetic, ACh and norepinephrine for sympathetic), and show differing functions (parasympathetic is involved in increasing energy stores, sympathetic is involved in energy expenditure).

Answer to Question 2

Answer: The hypothalamus is involved in the control of the pituitary, the sympathetic division of the ANS, and motivated behaviors including feeding, fighting, fleeing, and mating.
