Praxis 5857 Practice Test Practice Question
The fight-or-flight response occurs when which of the following is triggered as a person perceives a real or imaginary stressor?
Correct Answer: C
Rationale: The autonomic nervous system is responsible for regulating involuntary body functions, including the fight-or-flight response. When faced with a stressor, it activates the sympathetic division, preparing the body for quick action.
The integumentary system (A) primarily protects the body and regulates temperature, not directly involved in stress responses. The lymphatic system (B) supports immune function and fluid balance, lacking a direct role in immediate stress reactions. The muscular system (D) facilitates movement but does not initiate the physiological changes associated with stress. Thus, the autonomic nervous system is essential for managing stress responses effectively.
