Describe the primary physiological systems activated by the fight-or-flight response:

Question

The dermal system
Hornanl system
Sensory system

Answer 1

The fight-or-flight response primarily activates the nervous system, specifically the sympathetic nervous system. This triggers a cascade of physiological responses throughout the body to prepare it for a perceived threat or danger.

The dermal system is one of the systems activated, causing the skin to constrict blood vessels and reduce blood flow to the skin's surface. This can result in pale or flushed skin as blood is redirected to vital organs to aid in the fight-or-flight response.

The hormonal system is also activated, with the release of stress hormones such as adrenaline and cortisol. These hormones increase heart rate, blood pressure, and energy levels, preparing the body to either fight off the threat or flee from it.

The sensory system is heightened during the fight-or-flight response, with increased awareness and focus on the perceived threat. This can lead to dilated pupils, improved hearing, and a heightened sense of smell, all aimed at detecting and responding to danger more effectively.

Overall, the fight-or-flight response is a complex physiological reaction that prepares the body to respond to threats in its environment, with the activation of various systems working together to ensure survival.
