What does the autonomic nervous system control?

• A. Voluntary movements
• B. Involuntary muscles like the heart
• C. Skeletal movements
• D. Hormonal secretions

Answer: (B)

The autonomic nervous system is responsible for regulating involuntary physiological functions that occur within the body with little to no conscious control. This includes critical functions such as heart rate, digestion, respiratory rate, and the functioning of glands. The system is divided into two main branches: the sympathetic and parasympathetic nervous systems, which work together to maintain homeostasis. Involuntary muscles, such as those found in the heart, are controlled by this system because they operate automatically to ensure that vital functions continue without requiring conscious thought. This aspect of the autonomic nervous system is essential, as it allows the body to respond quickly to changes in internal and external environments, handling processes that are crucial for survival. With respect to the other options, voluntary movements are typically controlled by the somatic nervous system, which governs actions that involve conscious thought and muscular control over skeletal muscles. Skeletal movements are also under voluntary control, distinctly separated from the functions of the autonomic system. Hormonal secretions, while regulated by the nervous system to some extent, fall primarily under the control of the endocrine system, which manages hormone release through glands and is not strictly part of the autonomic nervous system's focus on involuntary functions.
