What division is used during emergency situations and promotes a heightened awareness state? A. Parasympathetic B. Sympathetic C. Autonomic D. Somatic

Step 1: Break Down the Problem

This question is asking about the appropriate division of the nervous system that is activated during emergency situations, specifically focusing on awareness states.

Step 2: Relevant Concepts

The human nervous system is divided into several components:

1. Sympathetic Division: Responsible for the body's 'fight or flight' response during emergencies.
2. Parasympathetic Division: Responsible for 'rest and digest' activities, promoting relaxation.
3. Autonomic Nervous System: This includes both sympathetic and parasympathetic systems and controls involuntary bodily functions.
4. Somatic Nervous System: Controls voluntary movements of skeletal muscles.

Step 3: Analysis and Detail

• The sympathetic division is activated in response to stress or emergencies. It increases heart rate, dilates airways, and enhances alertness through the release of adrenaline and other hormones.
• In contrast, the parasympathetic division typically slows heart rate and promotes a state of calm.
• Autonomic is too broad as it encompasses both sympathetic and parasympathetic responses.
• The somatic division is not directly involved in emotional or emergency responses but focuses on voluntary muscle control.

Step 4: Verify and Summarize

The sympathetic division prepares the body to respond to danger by heightening awareness and mobilizing energy. This is the correct answer when identifying the division activated during emergencies.

Final Answer

B. Sympathetic
