The Autonomic Nervous System: Sympathetic and Parasympathetic Divisions

Sympathetic versus Parasympathetic Nervous System | Nervous System

Autonomic Nervous System

 The activity of the sympathetic division is evident when we are excited or under emergency conditions. 

 The division of the autonomic nervous system that puts you into &quot;fight-or-flight&quot; mode is the __________. 

Sympathetic versus Parasympathetic Nervous System

 The parasympathetic division is often referred to as the “rest and digest” system. 

 The parasympathetic nervous system is often referred to as the “rest and digest” system.  

 Most parasympathetic ganglia are located in or near the visceral effector organ. 

 Sympathetic and parasympathetic divisions are part of the autonomic nervous system. 

 Most viscera are dually innervated by sympathetic and parasympathetic fibers. 

 Parasympathetic fibers have a craniosacral outflow. 

 The sympathetic division has short preganglionic fibers and long postganglionic fibers. 

 The two divisions of the somatic nervous system are sympathetic and parasympathetic. 

 Which of the following statements regarding the autonomic nervous system is NOT correct? 

 The four <i>E</i>s are associated with sympathetic stimulation. 

 Which of the following is associated with the parasympathetic system? 

 The sympathetic division is often referred to as the “fight-or-flight” system. 

 For which of the following activities is the sympathetic nervous system generally responsible? 

 Parasympathetic stimulation is associated with warm skin, indicating that there is no need to divert blood to the skeletal muscles or vital organs because the body is relaxing. Cold, sweaty skin is a sign of sympathetic activity. 

 Which of the following would NOT occur when the parasympathetic system is active? 

Parasympathetic Nervous System

 The somatic nervous system stimulates skeletal muscles. 

 What is the function of the somatic nervous system? 

2-Minute Neuroscience: Sympathetic Nervous System

 The parasympathetic division has long preganglionic neurons and short postganglionic neurons, whereas the sympathetic division has short preganglionic neurons and long postganglionic neurons. 

 The __________ division of the autonomic nervous system has its ganglia near the effector organs. 

 The sympathetic division is anatomically more complex than the parasympathetic division, partly because it innervates more organs. 

 The sympathetic division is anatomically more complex than the parasympathetic division.
