Chapter 3 Stress And Coping Stress - the non-specific mental or somatic result of any demand upon the body. Coping - strategies that an individual employs to deal with stresses caused by ever-changing demands of the environment. Stress Literacy - the degree to which an individual (or community) is knowledgeable about the affects of stress. Eustress - a positive yet stressful experience. Homeostasis - the dynamic physiological response on the part of the body to maintain a stable internal state in spite of the demands of the environment. Fight-Or-Flight Response - the body's complex autonomic reaction when faced with a perceived threat. Nervous System - one of the two major components of the physical response to stress; made up of the central nervous system and the peripheral nervous system. Endocrine System - a system of the body the controls glandular responses to stress, albeit more slowly than the nervous system but whose effects can persist for weeks. Central Nervous System - the division of the nervous system that is composed of the brain and the spinal cord. Peripheral Nervous System - the division of the nervous system that is made up of the somatic nervous system and the autonomic system (which is further divided into the sympathetic and the parasympathetic nervous systems). Hypothalamus - a portion of the brain that initiates the stress and response in both the nervous system and the endrocrine system. Adrenal Medulla - the central portion of the adrenal gland that secretes catecholamines (containing both adrenaline and noreadrenaline) when the hypothalamus initiates the stress response. Sympathetic Nervous System - the system responsible for the "fight-or-flight" response when triggered by the hypothalamus (eg., faster heartbeat, increased blood pressure). Limbic System - a system of the brain that is responsible, in part, for emotion in the stress response. Reticular Formation - complex system running through the middle of the brain stem that serves as a communication network to filter messages between the brain and the body. Parasympathetic Nervous System - the component of the autonomic system that re-establishes homeostatis in the system and promotes the reconstructive process following a stressful experience. Pituitary Gland - a gland located in the brain that is described as the master gland because of its control of other glands through the hormones it secretes. Most of these hormones have an indirect impact on stress. Adrenal Cortex - the outer portion of the adrenal gland that provides hormones to the body at times of stress. These hormones provide energy and increase blood pressure, but they can adversely affect the body's ability to resist disease and recover. Thyroid Gland - a gland that is important in the stress response because of its production of thyroxine,
