Question: 1 / 400

Which of the following describes a function of the autonomic nervous system?

Voluntary muscle movement

Heart rate

The autonomic nervous system (ANS) is responsible for regulating involuntary physiological functions, which includes the control of heart rate. This system operates without conscious control and manages functions such as breathing, digestion, and the beating of the heart. It adjusts heart rate based on the body's needs, such as when we are at rest or during physical exertion—this indicates its role in maintaining homeostasis.

In contrast, functions like voluntary muscle movement, conscious thought, and balance and coordination fall under the purview of the somatic nervous system and other neurological systems, which involves conscious control and coordination of movements. Understanding these distinctions highlights the crucial role that the autonomic nervous system plays in managing essential body functions without the need for conscious awareness.
