Verified step by step guidance1
Understand that the autonomic nervous system (ANS) is a subdivision of the peripheral nervous system responsible for involuntary control of body functions, such as heart rate, digestion, and respiratory rate.
Recognize that the ANS is divided into two main branches: the sympathetic division and the parasympathetic division, which work in opposition to maintain homeostasis.
The sympathetic division is often referred to as the 'fight or flight' system, as it prepares the body for stressful or emergency situations by increasing heart rate, dilating airways, and redirecting blood flow to muscles.
The parasympathetic division is known as the 'rest and digest' system, as it promotes relaxation and recovery by slowing the heart rate, stimulating digestion, and conserving energy.
Review the incorrect options provided in the question to confirm that none of them accurately describe the two main divisions of the autonomic nervous system, reinforcing that the correct answer is 'Sympathetic and Parasympathetic.'
