Flashcards in 164b feeding control Deck (10):
1

when should there be more E intake?

growth
pregnant
recovery from illness

2

components of E expenditure

10% PAL - physical activity level

10% TEF - thermic effect of food (E burned processing food)

80% BMR - basal metabolic rate (majority); depends on lean body mass

3

Ghrelin

only hunger stimulating hormone (orexigenic) --> hypothalamus


4

GLP-1

enhances glucose action on beta cells for increased insulin secretion

decreases hunger via vagus nerve

5

Liraglutide

GLP-1 analog for long term use

increases insulin
decreases glucagon release.

6

Exenatide

GLP-1 analog for long term use

increases insulin
decreases glucagon release.

7

leptin effect on lateral area of hypothalamus

lateral area controls hunger (destroy --> anorexia)

inhibited by leptin

7

leptin effect on lateral area of hypothalamus

lateral area controls hunger (destroy --> anorexia)

inhibited by leptin

8

leptin effect on ventromedial area

ventromedial area controls satiety (destroy --> hyperphagia

stimulate by leptin

8

leptin effect on ventromedial area

ventromedial area controls satiety (destroy --> hyperphagia

stimulate by leptin
