Examples of satiety in the following topics:

  • Hormones of the Digestive System

    • There are hormones secreted by tissues and organs in the body that are transported through the bloodstream to the satiety center, a region in the brain that triggers impulses that give us feelings of hunger or aid in suppressing our appetite.

  • The Endocrine System and Hunger

    • In the 1940s, the "dual-center" model, which divided the hypothalamus into hunger (lateral hypothalamus) and satiety (ventromedial hypothalamus) centers, was popular.
    • The short-term regulation of hunger deals with appetite and satiety.

  • Gastrointestinal Reflex Pathways

    • The effects range from excitatory or inhibitory effects on motility and secretion, to feelings of satiety or hunger when acting on the brain.

  • Neural Responses to Food

    • When the stomach is full, the part of the brain that detects satiety signals fullness.

  • Organs with Secondary Endocrine Functions

    • Leptin increases the activity of anorexigenic neurons and decreases that of orexigenic neurons, producing a feeling of satiety after eating, thus affecting appetite and reducing the urge for further eating.

  • Homeostatic Control

    • The most important example is the hypothalamus, a region of the brain that controls everything from body temperature to heart rate, blood pressure, satiety (fullness), and circadian rhythms (sleep and wake cycles).

  • Food Requirements and Essential Nutrients

    • Fats add flavor to food and promote a sense of satiety or fullness.
