What term describes any experience, environment, or object that disrupts the body's normal state of functioning?

• A. Stressor
• B. Stress response
• C. Fear
• D. Comfort

Answer: (A)

Stressor. In physiology, a stressor is any experience, environment, or object that disrupts the body's normal state of functioning, or homeostasis. When a stressor is encountered, the body activates a stress response to cope, triggering the sympathetic nervous system and releasing hormones like adrenaline and cortisol to prepare for action. In a veterinary context, examples include loud noises, unfamiliar people, restraint, or long wait times. Recognizing stressors is key to applying Fear Free strategies—reducing or controlling these factors, using calm handling, predictable routines, and positive reinforcement to minimize anxiety. Fear is the emotional state that can arise in response to stressors, while the stress response is the body's physiological reaction; comfort means the absence of disruption.
