Expert verified
Answer: D. sympathetic division of the autonomic nervous system

Step by step solution

Analyze the given answer choices

Read and understand the difference between the answer choices: A. empathetic division of the peripheral nervous system B. parasympathetic division of the autonomic nervous system C. somatic division of the peripheral nervous system D. sympathetic division of the autonomic nervous system Each of these choices represents a different division of the nervous system, so it is important to understand the functions of each before selecting an answer.
02

Understand the functions of the divisions

A. There is no "empathetic" division, so this choice can be eliminated. B. Parasympathetic division is responsible for the "rest and digest" response, which helps the body conserve energy and maintain normal body functions. This is not the correct answer for the fight-or-flight response. C. Somatic division controls voluntary muscle movements, not the autonomic responses involved in fight-or-flight. D. Sympathetic division prepares the body for action in an emergency, like a "fight-or-flight" response.
