Document Summary
12/6/17: week 12: hunger and eating behaviors and sleep. Psyc 2012: final exam: know the different hypothalamic nuclei involved in regulating hunger and satiety and which they are involved in regulating (hunger, satiety, or both). Ventromedial hypothalamus (vmh) and paraventricular nucleus (pvn): satiety centers. Arcuate nucleus (an): regulates both hunger and satiety: know the neurotransmitters associated with the satiety pathway and neurotransmitters associated with the hunger pathway. In response to hunger cues one set of arcuate nucleus neurons releases neuropeptide y (npy) on to lh hunger center neurons, activating them. In response to satiety cues another set of arcuate nucleus cells releases melanocyte stimulating hormone (msh) onto satiety center neurons in the. Vmh and pvn and activates them: know the different hunger and satiety signals and what increases their levels. Cholecystokinin (ckk) - a peptide released by the stomach when it has food in it. Glucose - blood levels rise during absorption.
