Verified step by step guidance1
Understand the autonomic nervous system (ANS): The ANS is a part of the peripheral nervous system that controls involuntary bodily functions such as heart rate, digestion, and respiratory rate.
Identify the divisions of the autonomic nervous system: The ANS is divided into the sympathetic and parasympathetic nervous systems.
Differentiate between the sympathetic and parasympathetic systems: The sympathetic nervous system prepares the body for 'fight or flight' responses, while the parasympathetic nervous system promotes 'rest and digest' activities.
Recognize the control nature of the sympathetic nervous system: The sympathetic nervous system is typically under involuntary control, meaning it operates without conscious input to manage stress responses.
Conclude that the sympathetic nervous system is the division of the autonomic nervous system usually under involuntary control, as it automatically regulates the body's response to stress and emergencies.
