Verified step by step guidance
1
Understand the role of the autonomic nervous system (ANS): The ANS is responsible for regulating involuntary physiological functions, including heart rate, blood pressure, respiratory rate, digestion, and sexual arousal.
Identify the functions listed in the problem: Managing respiratory rate, initiating voluntary muscle movement, regulating heart rate, and controlling digestive processes.
Determine which functions are involuntary: Managing respiratory rate, regulating heart rate, and controlling digestive processes are all involuntary functions typically managed by the ANS.
Recognize the function that is voluntary: Initiating voluntary muscle movement is controlled by the somatic nervous system, not the autonomic nervous system.
Conclude that the function NOT managed by the ANS is initiating voluntary muscle movement, as it involves conscious control and is not an involuntary process.
