Responses to Stress - MCAT Psychological and Social Foundations

The stress response is initated when epinephrine raises blood pressure and increases the production of glucose from stored glycogen. Glycogen is thus diminished when stress occurs. Glucagon is a hormone secreted by the pancreas in response to low blood glucose that causes the liver to release glucose into the bloodstream. Glycol is an alcohol related to ethylene glycol, which is found in antifreeze. A glycoside is a substance in which a sugar and a functional group are attached via a glycosidic bond. Gluten is a group of proteins that give flour its stickiness. Gluten sensitivity causes gastrointestinal problems.

According to the “James Lange theory,” an external stimulus will cause a physiological reaction, which is then interpreted by the brain and translated to an emotion. In this scenario, the boys saw something, reacted, and interpreted this reaction as an emotion: scared.

The other answers are incorrect choices. “Cannon-Bard theory” states that emotion and physiological response occur at the same time. “Two-factor theory” of emotion includes an element of examining one’s environment to help decipher physiological responses. Last, “appraisal theory” hypothesizes that emotions are based on personal evaluations of a given situation. For example, a student that believes a test went very well would feel happy. In this situation, we do not know how the boys evaluated the situation before they felt fear.

The body's initial response to stress in initiated by the hormone epinephrine, which raises blood pressure, raises cardiac output, and increases glucose production from stored glycogen. If stress is allowed to persist, the adrenal gland increases its output of cortisol to stimulate glucose synthesis. Insulin and glucagon are secreted by the pancreas. Insulin is secreted in response to high levels of blood sugar while glucagon is secreted in response to low levels of blood sugar. Gastrin is secreated by the stomach and secretion diminishes in times of stress.
