appetite hormones Flashcards
what hormone secreted from adipose and stomach and decreases after fasting and increases after post prandial ( after meal )
leptin
satiety
where does leptin act
brainstem and hypothalamus and vagus nerve
Moa of leptin
decreases food intake and indicates level of energy stored as fat
what hormones secreted in stomach and increases pre-meal ( hunger hormone ) and decreases after meal
gherlin- hunger
where does ghrelin act and Moa
brain on hypothalamus and vague nerve
increases food intake
what hormone decreases food intake and is secreted from the pancreas acting on the hypothalamus. it increased after a meal and is involved with glucose metabolism
insulin
what horse secreted by duodenum and increases after a meal decreasing food intake but has an extra functioning acting on the GI tract and vagus nerve to decrease gastric emptying
CCK - cholecystokinin
what hormone is secreted by the ileum and increased after a meal with fats, proteins and carbs acting of vagus and GI tract and decreasing food intake and decrease gastric emptying
GLP-1
what hormone secrete in ileum and colon and increases after meal and causes gastric distention. it decrease food intake and gastric motility
PYY3-36
ghrelin produced by what cells
P/D1 cells in fundus of stomach
levels of what hormone increase in weight loss
basal ghrelin
sleeve and RYGB remove these cells
PYY3-36 is a satiety hormone and secreted in presence of nutrient secreted by what cells
L-cells found in intestines
leptin levels reflect
amount of adipose tissue
GLP-1 secreted by what cells
L-cells
GLP-1 has also been shown to influence β cell mass by stimulating β cell proliferation.
