Question: 1 / 565

How does muscle tension react in response to a critical incident?

Muscles relax significantly

No change occurs

Muscles remain loose

Muscles tighten

During a critical incident, the body's natural response includes a significant increase in muscle tension, commonly referred to as the "fight or flight" response. This reaction is part of the body's sympathetic nervous system activation, which prepares an individual to respond to perceived threats. When faced with stress or danger, adrenaline is released, leading to physiological changes, including increased heart rate, heightened awareness, and muscle tightening. This muscle tension is a way for the body to prepare for physical action, whether that involves fighting or fleeing from the threat. As a result, the correct response regarding muscle behavior during a critical incident is that muscles tighten, helping individuals to react swiftly and effectively in high-stress situations.
