| 9006761030 | DIATHESIS STRESS MODEL | "mental illnesses occur due to stressful conditions in the environment interacting with the biological and psychological characteristics of the individual" (Nature & Nurture) the model assumes that mental disorders require a predisposition towards the disease and provides an explanation as to why only one out of the two people living in stressful conditions will develop a mental disorder, that person being the one with a biological predisposition. | 36 | |

| 9006799411 | HORMONE ACTION | hormones are released by glands that then travel through the blood to affect different parts of the body. hormones attach to specific receptor sites on cells, triggering a change in that cell. - only certain hormones fit specific receptors | 38 | |
