Psych 300 Final Quiz - Chapter 10 Hunger

Front 1

AgRP (agouti-related peptide)

Back 1

inhibitory neurotransmitter found in the areas of the hypothalamus that regulate feeding

Front 2

anorexia nervosa

Back 2

condition characterized by unwillingness to eat, severe weight loss, and sometimes death

Front 3

arcuate nucleus

Back 3

hypothalamic area with one set of neurons sensitive to hunger signals and another sensitive to satiety signals

Front 4

bulimia nervosa

Back 4

condition characterized by alternation between dieting and overeating

Front 5

carnivore

Back 5

meat eater

Front 6

cholecystokinin (CKK)

Back 6

hormone released by the duodenum in response to food distention

Front 7

conditioned taste aversion

Back 7

learned avoidance of a food whose consumption is followed by illness

Front 8

cytokines

Back 8

chemicals released by the immune system that attack infections and communicate with the brain to elicit anti-illness behaviors

Front 9

duodeum

Back 9

part of the small intestine adjoining the stomach; the first part of the digestive system that absorbs food

Front 10

ghrelin

Back 10

chemical released by stomach during food deprivation; also released as a neurotransmitter in the brain, where it stimulates eating

Front 11

glucagon

Back 11

pancreatic hormone that stimulates the liver to convert stored glycogen to glucose

Front 12

herbivore

Back 12

animals that eat plants

Front 13

homeostasis

Back 13

tendency to maintain a variable, such as temperature, within a fixed range

Front 14

insulin

Back 14

pancreatic hormone that facilitates the entry of glucose into the cells

Front 15

lactase

Back 15

enzyme necessary for lactose metabolism

Front 16

lactose

Back 16

the sugar in milk

Front 17

lateral hypothalamus

Back 17

area of the hypothalamus that is important for the control of eating and drinking

Front 18

lateral preoptic area

Back 18

portion of the hypothalamus that includes some cells that facilitate drinking and some that inhibit it, as well as passing axons that are important for osmotic thirst

Front 19

leptin

Back 19

peptide released by fat cells; tends to decrease eating, partly by inhibiting release of neuropeptide Y in the hypothalamus

Front 20

melanocortin

Back 20

type of chemical that promotes satiety in the hypothalamus

Front 21

neuropeptide Y (NPY)

Back 21

peptide found in the brain, especially the hypothalamus; it inhibits activity of the paraventricular nucleus and thereby increases meal size

Front 22

omnivore

Back 22

animals that eat both meat and plants

Front 23

paraventricular nucleus (PVN)

Back 23

area of the hypothalamus in which activity tends to limit meal size and damage leads to excessively large meals

Front 24

preoptic area/anterior hypothalamus (POA/AH)

Back 24

brain area important for temperature control

Front 25

set point

Back 25

level at which homeostatic processes maintain a variable

Front 26

sham feeding

Back 26

procedure in which everything that an animal swallows leaks out a tube connected to the esophagus or stomach

Front 27

sodium-specific hunger

Back 27

enhanced preference for salty tastes during a period of sodium deficiency

Front 28

ventromedial hypothalamus

Back 28

region of the hypothalamus in which damage leads to faster stomach emptying and increased secretion of insulin
