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. -CORRECT ANS 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.
1. The hormones being released as the stomach stretches is leptin, seratonin, and
CCK. These hormones decrease hunger, in specific leptin. They acitvate the satiety
center in the brain which creates a sense of fullness.
2. The area of the brain that provides nerual regulation and appetite suppression to
inhibit eating is the satiety center.
