Apr 3, 2024 · The stress response begins in the brain (see illustration). When someone confronts an oncoming car or other danger, the eyes or ears (or both) send the information to the amygdala, an area of the brain that contributes to emotional processing.

Nov 9, 2023 · Stress is a biological and psychological response experienced upon encountering a threat that we feel we do not have the resources to deal with. A stressor is a stimulus (or threat) that causes stress, e.g., an exam, divorce, the death of a loved one, moving house, or loss of job.
Jan 4, 2024 · Stress responses lend themselves well to exploring molecular mechanisms. Rather than waiting for something to happen—such as waiting for an organism to develop—measuring a response to an acute perturbation can provide quick insights into many biological pathways.
Oct 17, 2020 · Stress constitutes a state of threatened homeostasis triggered by intrinsic or extrinsic adverse forces (stressors) and is counteracted by an intricate repertoire of physiologic and behavioral responses aiming to maintain/reestablish the optimal body equilibrium (eustasis).

Biology primarily attempts to explain major concepts of stress using a stimulus-response paradigm, broadly comparable to how a psychobiological sensory system operates. The central nervous system (brain and spinal cord) plays a crucial role in the body's stress-related mechanisms.
Oct 29, 2024 · stress, in psychology and biology, any environmental or physical pressure that elicits a response from an organism. In most cases, stress promotes survival because it forces organisms to adapt to rapidly changing environmental conditions.
