|\ |\ |\ |\ |\ |\ |\ |\ |\



influence our desire to eat. - CORRECT ANSWERS ✔✔The internal
|\ |\ |\ |\ |\ |\ |\ |\ |\



drive is hunger and is associated with negative sensations like
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



churning, growling and pain in the stomach. External drives have to

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 ANSWERS ✔✔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.
