Which division of the autonomic nervous system is responsible for the fight or flight response?

• A. Visceral
• B. Sympathetic
• C. Parasympathetic
• D. Somatic

Answer: (B)

The sympathetic division of the autonomic nervous system is responsible for the fight or flight response. This response is activated in situations perceived as stressful or dangerous, preparing the body to react. When the body encounters a threat, the sympathetic nervous system triggers a series of physiological changes. These include an increase in heart rate, dilation of the airways, and a surge in adrenaline, all of which enhance the body's ability to respond to immediate challenges. The sympathetic system contrasts with the parasympathetic division, which helps maintain homeostasis and conserves energy during non-stressful conditions by promoting "rest and digest" functions. The visceral and somatic divisions refer to different aspects of the nervous system that are not primarily involved in the fight or flight response. Visceral relates more to the involuntary control of internal organs, while somatic pertains to voluntary muscle movements.
