MD Sympathetic division Parasympathetic division 1- Increased alertness via stimulation of the reticular activating system, causing the individual to feel “on edge.” 2-Constriction of the pupils (to restrict the amount of light that enters the eyes) and focusing the lenses of the eyes on nearby objects. 3-Increased activity in the cardiovascular and respiratory centers of the pons and medulla oblongata, leading to elevations in blood pressure, heart rate, breathing rate, and depth of respiration. 4-Secretion by digestive glands, including salivary glands, gastric glands, duodenal glands, intestinal glands, the pancreas (exocrine and endocrine), and the liver.

Most postganglionic fibers release NE, but a few release ACh or NO. 8-All neurons release ACh as a neurotransmitter. 9-The preganglionic fibers are short, because the ganglia are close to the spinal cord. The postganglionic fibers are longer 10-The division includes visceral motor nuclei associated with cranial nerves III, VII, IX, and X and with sacral segments Defining Feature Matrix.
