The concept of integrative function. Physiological and behavioural mechanisms for the maintenance of homeostasis. The regulation of nutritional functions. The balance of energy reserves. The hypothalamic centers of hunger and satiety. Hypothalamic nuclei and glucoreceptors. Endocrine-hypothalamic axis in the regulation of the energy balance. Physiological indicators of hunger and the integration of hunger signals.
Regulation of the water-saline balance. Modifications of the hydro-saline compartments and compensating mechanisms. The role of the kidney. Central and peripheral osmotrceptors and volume receptors. The ADH system.
The balance of sodium and potassium. Regulation of serum sodium and potassium.
The basics of behavior and food choices. Motivation. Interaction between homeostasis and incentives.
