Chapter 15 Flashcards & Key Terms

adaptation stage
The second stage in the stress response, including successful activation of the appropriate response systems and the reestablishment of homeostatic balance.
alarm reaction
The initial response to stress.
amygdala
A group of nuclei in the medial anterior part of the temporal lobe.
antibody
Also called immunoglobulin. A large protein that recognizes and permanently binds to particular shapes, normally as part of the immune system attack on foreign particles.
B lymphocyte
Also called B cell. An immune system cell, formed in the bone marrow (hence the B), that mediates humoral immunity.
Bell’s palsy
A disorder, usually caused by viral infection, in which the facial nerve on one side stops conducting action potentials, resulting in paralysis on one side of the face.
brain self-stimulation
The process in which animals will work to provide electrical stimulation to particular brain sites, presumably because the experience is very rewarding.
cytokine
A protein that induces the proliferation of other cells, as in the immune system.
decorticate rage
Also called sham rage. Sudden intense rage characterized by actions (such as snarling and biting in dogs) that lack clear direction.
emotional dyscontrol syndrome
A condition consisting of temporal lobe disorders that may underlie some forms of human violence.
evolutionary psychology
A field devoted to asking how natural selection has shaped behavior in humans and other animals.
exhaustion stage
A stage in the response to stress that is caused by prolonged or frequently repeated stress and is characterized by increased susceptibility to disease.
health psychology
Also called behavioral medicine. A field that studies psychological influences on health-related processes, such as why people become ill or how they remain healthy.
individual response stereotypy
The tendency of individuals to show the same response pattern to particular situations throughout their life span.
intermale aggression
Aggression between males of the same species.
Klüver-Bucy syndrome
A condition, brought about by bilateral amygdala damage, that is characterized by dramatic emotional changes including reduction in fear and anxiety.
limbic system
A loosely defined, widespread group of brain nuclei that innervate each other to form a network. These nuclei are implicated in emotions.
medial forebrain bundle
A collection of axons traveling in the midline region of the forebrain.
Papez circuit
A group of brain regions within the limbic system.
phagocyte
An immune system cell that engulfs invading molecules or microbes.
polygraph
Popularly known as a lie detector. A device that measures several bodily responses, such as heart rate and blood pressure.
psychoneuroimmunology
The study of the immune system and its interaction with the nervous system and behavior.
psychopath
An individual incapable of experiencing remorse
psychosomatic medicine
A field of study that emphasizes the role of psychological factors in disease.
stress immunization
The concept that mild stress early in life makes an individual better able to handle stress later in life.
stress
Any circumstance that upsets homeostatic balance.
T lymphocyte
Also called T cell. An immune system cell, formed in the thymus (hence the T), that attacks foreign microbes or tissue; “killer cell.”
