Multiple Choice

While applying a tourniquet to stop life-threatening bleeding in a child, the child starts to cry. Which division of the autonomic nervous system is primarily responsible for the physiological responses associated with this emotional reaction?

Sympathetic nervous system

Parasympathetic nervous system

Somatic nervous system

Enteric nervous system

Verified step by step guidance

Understand the autonomic nervous system (ANS) and its two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic division is responsible for the 'fight or flight' response, while the parasympathetic division manages 'rest and digest' functions.

Recognize that the somatic nervous system controls voluntary movements of skeletal muscles and is not part of the autonomic nervous system. The enteric nervous system regulates gastrointestinal functions and is also not involved in emotional responses.

Identify the physiological responses associated with crying, such as increased heart rate, rapid breathing, and heightened alertness. These are characteristic of the sympathetic nervous system's activation during stress or emotional reactions.

Consider the context of the situation: applying a tourniquet to stop life-threatening bleeding is a stressful event that likely triggers the sympathetic nervous system to prepare the body for action and cope with the emotional stress.

Conclude that the sympathetic nervous system is primarily responsible for the physiological responses associated with the child's emotional reaction, as it governs the body's response to stress and emotional stimuli.
