⩥ You are at an "all you can eat'' buffet. On the first pass through the
line, you fill your plate with a large quantity of foods. After eating it,
you go back for a second portion of the foods you liked. However, the
food is less appealing the second time around, and you place a smaller
quantity on your plate because you feel full. Considering the physiology
as you eat, (1) explain what hormones are released (list specifically) as
the stomach stretches. (2) List the area of the brain that provides neural
regulation and appetite suppression to inhibit eating.. Answer: As the
stomach is filled and stretches, hormones are released that cause satiety
(Leptin, serotonin, cholecystokinin (CCK). These hormones can travel to
the brain (hypothalamus) and activate the satiety center.
