The autonomic nervous system is made up of two divisions. There are many differences between these divisions. First of all there are anatomical and physiological differences. The parasympathetic division of the autonomic system origin is in the craniosacral outflow, the brain stem nuclei of cranial nerves III, VII, IX, and X; and spinal cord segments S2-S4. The sympathetic division on the other hand is much more complex than the parasympathetic and is originated in the thoracolumbar outflow. Also, in the lateral horn of gray matter of the spinal cord segments of thoracic 1 to lumbar 2. Another important physiological difference is the location of ganglia in each division. Ganglia of the parasympathetic division are in intramural or close to the visceral organ served. The sympathetic ganglia are located with in a few centimeters of the central nervous system. They are also alongside the vertebral column and anterior to the vertebral column.
The relative length of preganglionic
I found the assignment a little different then most papers I have written do to one fact. I found that I could not put what the book said into my own words. I don't have a wide anatomical vocabulary, so I found that I had to copy a lot of what the book said. I am sure this is similar to some students in the class.
The parasympathetic division decreases the rate of the heart and slows it down. The sympathetic division increases the rate and force of the heart. The bladder in both divisions is opposite once again. In the parasympathetic of the bladder, the contraction of smooth muscle and the relaxation in the sympathetic division. The parasympathetic constricts for the bronchioles of the lungs, where the bronchioles are dilated in the sympathetic. The liver's sympathetic effect is in epinephrine stimulus of the liver to release glucose to the blood. There is no parasympathetic effect of the liver. In the parasympathetic division the gallbladder contracts to expel bile. In the sympathetic division the gallbladder is relaxed. Th
