A mugger steals your wallet causing all of the following to happen EXCEPT __.
Question 13 options:
inability to read close-up print
increased rate and force of heartbeat
increased metabolic rate
increased glucose uptake to the liver from blood
The Correct Answer and Explanation is :
The correct answer is inability to read close-up print.
Here’s an explanation of why:
When a mugger steals your wallet, it triggers a fight or flight response, a natural physiological reaction to stress or danger. This response is activated by the sympathetic nervous system and is part of the body’s preparation to either confront or flee from a perceived threat. Let’s break down each of the options and understand why they happen:
- Increased rate and force of heartbeat: This occurs because the sympathetic nervous system releases adrenaline (epinephrine), which stimulates the heart to beat faster and stronger. The body is preparing for quick action, whether it’s running away or standing ready to confront the threat. This is a typical response to stress or fear.
- Increased metabolic rate: In response to stress, the body activates systems that increase the metabolic rate. This ensures that energy is quickly available to the muscles, brain, and other organs involved in the “fight or flight” response. The body needs more fuel (energy) to perform physical actions that might be necessary for survival.
- Increased glucose uptake to the liver from blood: The liver plays a key role in the body’s response to stress. Under stress, the liver releases glucose (via glycogen breakdown) into the bloodstream to provide immediate energy for muscles and vital organs. This is a part of the fight or flight response, ensuring the body is primed for quick, intense action.
- Inability to read close-up print: This is not a response to a stressful event like the others. Instead, it is typically associated with age-related changes or certain vision conditions like presbyopia, where the ability to focus on near objects declines. Stress and fear don’t cause this specific change, so it’s the correct answer here.
In summary, while your body prepares for immediate action in response to stress, such as increasing heart rate, metabolic rate, and glucose availability, the inability to read close-up print is unrelated to this physiological response.
