Want this question answered?
the autonomic nervous system (ANS) includes the peripheal nerves and ganglia on either side of the spinal cord ( note: some textbooks include the ANS as a division pf the peripheal nervous system both ways are correct.)
The Autonomic Nervous System (ANS) regulates the action of smooth muscles, cardiac muscle, and some glands.In other words, the ANS regulates involuntary (automatic; unconscious) actions.There are two major divisions of the ANS. The parasympathetic division functions under normal conditions (to maintain homeostasis), and the sympathetic division of the ANS functions under stress.Some times the sympathetic divison is called the "Fight or Flight" response and the parasympathetic division is called the "Rest and Repose {turkey dinner syndrome)" response.
The brain can influence the heart in two ways. Sympathetic and parasympathetic stimulation. Parasympathetic stimulation of the heart is through the vagus nerve. Sympathetic stimulation of the heart is via cervical and thoracic splanchnic nerves. The heart has its own pacemaker cells, so the brain only changes the rate and contractility of the heart.
The nervous system can be divided into two components in several ways. First, you can divide the nervous system into central (brain and spinal cord) and peripheral (the rest of the nerves). Second, you can divide the system into autonomic and voluntary. Third, you can divide the system into sympathetic and parasympathetic.
Only one but there are several divisions of it such as central vs peripheral or sympathetic vs parasympathetic nervous system. It's all one but different ways of dividing it up to make sense of it.
