Best answer: What is the main function of the parasympathetic division of the autonomic nervous system quizlet?

The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body’s rest-and-digest response.

What is the main function of the parasympathetic division of the autonomic nervous system?

The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.

What is the function of the parasympathetic nervous system quizlet?

The parasympathetic nervous system is one of three divisions of the autonomic nervous system.

What are the major functions of the sympathetic and parasympathetic nervous system?

The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.

What are the three parts of the autonomic nervous system?

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.

How does the parasympathetic system affect digestion?

The parasympathetic nervous system controls processes in the body such as digestion, repair and relaxation. When the parasympathetic nervous system is dominant in the body it conserves energy, slows heart rate, increases digestion and relaxes sphincter muscles in the digestive tract.

Which of the following is a function of the parasympathetic?

The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body’s rest-and-digest response.

Which best describes the function of the parasympathetic nervous system?

The parasympathetic nervous system is responsible for calming the body and conserving energy. As the body conserves energy, pupils contract, heartbeat slows, blood pressure decreases, and digestion is stimulated.

What do parasympathetic and sympathetic have in common?

What do the parasympathetic and sympathetic divisions have in common? Most nerve fibers from both divisions innervate many of the same effectors. Most nerve fibers from both divisions share the same sites of origin. The preganglionic nerve fibers in both divisions are of similar length.
