PSYC 5100 Quiz 4 With Complete Solutions!!
Anticipation of Food Neural and endocrine signaling in anticipation of food is critical for
maintaining energy balance. Particularly:
।activation of appetite-stimulating or anorexigenic systems
the ghrelin and insulin increase before:
daily, ANSWER>>to food availability
What is initiated first in the food onset? - ANSWER>>meal anticipation:
odour, vision of food
time of the day
environment factor
What signaling occurs with the food onset? - ANSWER>>parasympathetic signaling
What organs are affects after parasympathetic signaling of food onset? -
ANSWER>>stomach, intestines, and pancreas
What two hormones decrease after the meal?` - ANSWER>>insulin and ghrelin
what gut hormone peptide decreases when affecting satiety? - ANSWER>>CCK and
GLP-1
what gut hormone peptide increases when affecting satiety? - ANSWER>>ghrelin
What state is this?
food is broken down into glucose, free fatty acids, and amino acids. Glucose powers the
, brain and muscles.
insulin is released from the pancreas to facilitate transport of glucose.
excess glucose is converted to glycogen and stored in the liver and muscles. -
ANSWER>>well-fed state
What state is this?
glucagon is released from the pancreas.
glycogenolysis breaks down stored glycogen in the liver.
lipolysis in adipose tissue releases free fatty acids and glycerol.
"liberated" glucose and ketone bodies power the brain. - ANSWER>>fasting state
What is the travel of signals of adiposity? -ANSWER>> Body fat mass (lipids and ghrelin)
- hypothalamus to catabolic and anabolic pathways - to brainstem
What is travel of satiety signals -ANSWER GI tract ( liver & stomach initiate energy
metabolism and CCK) - vagus nerve, superior cervical ganglia, and c-spine SNS
afferents (GLP-1 & others ) - to the brainstem
The parasympathetic afferent (sensory) pathways is AKA: - ANSWER>>vagus nerve
• Fear, arousal (mostly negative, though some positive), defensive behaviors, stress
responses; fear learning. - ANSWER>>amygdala
• Emotion regulation (through connection from PFC to amygdala) -
ANSWER>>prefrontal cortex
