Answer 1

Question	Sympathetic	Parasympathetic
Length of preganglionic fibers	Shorter	Longer
Neurotransmitters released from preganglionic fibers	Cholinergic (Acetylcholine)	Cholinergic (Acetylcholine)
Location of the preganglionic neurons in the spinal cord	Thoracolumbar: Cell bodies of preganglionic neurons are located in the intermediolateral cell column of spinal cord segments T1 to L2.	Craniosacral: Cell bodies of preganglionic neurons are located in either brainstem nuclei (associated with cranial nerves III, VII, IX, and X) or the sacral autonomic nucleus (lateral gray column) of spinal cord segments S2 to S4.
Neurotransmitters released from postganglionic fibers	Adrenergic (Epinephrine and Norepinephrine)	Cholinergic (Acetylcholine)
