Which statement best describes how the autonomic and endocrine systems coordinate the stress response?

• A. The autonomic nervous system initiates rapid responses via neurotransmitters, while the endocrine system provides longer-lasting hormones like cortisol
• B. The endocrine system initiates rapid responses via hormones
• C. The autonomic nervous system and endocrine system coordinate by combining rapid neural signaling with longer-lasting hormonal effects
• D. The autonomic system only affects digestion

Answer: (C)

The stress response is coordinated by two systems that work on different time scales but toward the same goal: rapid adjustment through neural signaling and sustained adjustment through hormones. The autonomic nervous system acts first and fast, sending neurotransmitters that quickly change heart rate, blood flow, and airway diameter to ready the body for action. At the same time, the endocrine system releases hormones like cortisol (and adrenaline from the adrenal medulla) which take a bit longer to exert effects but keep energy mobilization and physiological readiness going for minutes to hours. This combination explains why the best description is that they coordinate by combining rapid neural signaling with longer-lasting hormonal effects. Some statements misstate the timing—hormones don’t typically produce rapid responses, and saying the autonomic system only affects digestion ignores its broad role in many organs—so they don’t capture the full, integrated coordination.
