how is stressed releated to hunger?
stress increases arousal and is linked to increased food consumption
stimulation of the ventromedial hypothalmus causes what?
animal to stop eating
Emotion:
a feeling or display of feeling made in response to an event that has significance (environment, memories, etc.)
Insulin injections stimulate what?
hunger
What does the hypothalmus do physiologically?
governs physiologic functions such as temperature regulations, thirst, hunger, sleep, mood, sex drive and the release of other hormones within the body.
what do you do to the lateral hypothalmus and ventromedial hypothalmus to cause the animal to eat continously?
stimulate lateral hypothalmus and destruct ventromedial hypothalmus
Define obesity:
exceeds ideal body weight by 20+%
define anorexia nervosa:
fails to maintain ideal body weight at a minimum of 85%
Drive reduction:
state of relief and reward produced by removing the tension and arousal of the drive state
the stimulation of the lateral hypothalmus causes what?
animal to eat continously, become more hungry
explain the James-lange theory:
experience a stimulus, physiologically react, and then experience an emotion
Drive:
state of tension and arousal triggered by cue important for survival
explain the cannon-bard theory:
experience a stimulus, subcortically become active, and then physiologically react and experience an emotion
what do you do to the lateral hypothalmus and ventromedial hypothalmus to cause the animal to stop eating?
destruct lateral hypothalmus and stimulate the ventromedial hypothalmus
What is the glucostatic theory?
glucose levels impact feelings of satiation
what are the names of the four theoryies of emotion?
- common sense theory 2. James-lange theory 3. Cannon-bard theory 4. Two-factor theory
destruction of the ventromedial hypothalmus causes what?
animal to eat continously
low leptin levels stimulate what?
hunger
what is a stomach signal that can signal us to stop eating!
the vagus nerve sends signal about the stretching of the stomach.
what are some of the increases risks with obesity?
CVD. CHD, hypertension, diabetes, stroke, arthritis, back problems etc.
The destruction of the lateral hypothalmus causes what?
animal to stop eating, become less hungry
explain the common sense theory:
experience a stimulus, experience an emotion, then physiologically react.
the hypothalmus is responsible for the production of what?
many of the body’s essential hormones, chemical substances. These help control different cells and organs.
Why is motivation and emotion put together?
share subjective feelings and engage in similar processes in the brain
