Which of the following characteristics is not attributed to the sympathetic division of the ANS?
A) It originates in the thoracolumbar region of the spinal cord
B) It has a long postpanglionic fibers
C) It has a long preganglionic fibers
D) Its glangia are adjacent to the spinal column
E) It has an extensive neural divergence and a relative widespread effect
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
somatic (voluntary) nervous system-controls the movements of the skeletal muscles
autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
enteric nervous system-controls the function of the gastrointestinal tract.
