In the context of Advanced Placement Psychology, a key term describes a hormone and neurotransmitter primarily associated with the “fight-or-flight” response. Secreted by the adrenal glands, this substance prepares the body for intense physical exertion by increasing heart rate, blood pressure, and energy supplies. For instance, encountering a sudden threat, such as a near-miss car accident, triggers its release, resulting in heightened awareness and physical readiness.
Understanding this concept is fundamental to comprehending stress responses and emotional regulation. Its influence extends beyond immediate reactions to encompass long-term effects on physical and mental health. Historically, its role in survival mechanisms has been crucial for human adaptation, allowing individuals to react quickly to danger and ensure their safety. Recognizing its physiological and psychological impact provides insights into various stress-related disorders and coping mechanisms.
