Emotion, Stress and Health Flashcards
What is the adaptive immune system?
the division of the immune system that mounts targeted attacks on foreign pathogens by binding to antigens in their cell membrane
What is the adrenal cortex?
the outer layer of each adrenal gland, which releases glucocorticoids in response to stressors, as well as small amounts of steroid hormones
What is the adrenal medulla?
the core of each adrenal gland, which releases epinephrine and norepinephrine in response to stressors
What is an adrenalectomy?
surgical removal of the adrenal glands
What is adrenocorticotropic hormone (ACTH)?
an anterior pituitary hormone that triggers the release of adrenal hormones from the adrenal cortices
What is an alpha male?
the dominant male of a colony
What is the amygdala?
A structure in the anterior temporal lobe, just anterior to the hippocampus; plays a role in emotion
What are antibodies?
proteins that bind to foreign antigens on the surface of microorganisms and in doing so promote the destruction of the microorganisms
What is antibody-mediated immunity?
the immune reaction in which B cells destroy invading microorganisms via the production of antibodies
What are B-cells?
B lymphocytes; lymphocytes that manufacture antibodies against antigens they encounter
What is bullying?
a chronic social threat that induces subordination stress in members of our species
What is Cannon-Bard theory?
the theory that emotional experience and emotional expression are parallel process that have no direct causal relation
What is cell-mediated immunity?
the immune reaction by which T cells destroy invading microorganisms
What is the central nucleus of the amygdala?
a nucleus of the amygdala that is thought to control defensive behaviour
What is contextual feat conditioning?
the process by which benign contexts (situations) come to elicit fear through their association with fear-inducing stimuli
What is the control-question technique?
a lie-detection interrogation method in which the polygrapher compares the physiological responses to target questions with the responses to control questions
What is corticosterone?
the predominant glucocorticoid in humans
What are cytokines?
a group of peptide hormones that are released by many cells and participate in a variety of physiological and immunological responses, causing inflammation and fever
What does decorticate mean?
lacking a cortex
What are defensive behaviours?
behaviours whose primary function is protection from threat or harm
What is a Duchenne smile?
a genuine smile, one that includes contraction of the facial muscles called the orbicularis oculi
What does epigenetic mean?
the study of all mechanisms of inheritance other than the genetic code and its expression
What is the facial feedback hypothesis?
the hypothesis that our facial expression can influence the emotions we experience
What is fear?
the emotional reaction that is normally elicited by the presence or expectation of threatening stimuli
