Afferent signals regulating food intake.
Food intake is a regulated system. Afferent signals provide information to the central nervous system, which is the centre for the control of satiety or food seeking. Such signals can begin even before food is ingested through visual, auditory and olfactory stimuli. One of the recent interesting findings is the demonstration that there are selective fatty acid taste receptors on the tongue of r...
متن کاملRegulating food intake.
EVERY ORGANISM INGESTS FOOD (energy). If it takes in too little, it will starve; if it takes in too much, it will become obese. Too little is readily defined as caloric intake less than expenditure, and too much is simply the opposite. Multiple regulatory pathways are known that promote and inhibit feeding and thus regulate energy balance. However, these pathways and their interactions remain i...
متن کاملNeural and hormonal mechanisms regulating food intake.
In this outline of the neural control of food intake, no attempt has been made to provide a comprehensive survey of the literature since there are several symposia and reviews available which summarize the extensive work in this field (Grossman, 1975; Novin et al. 1976; Silverstone, 1976; Morgane & Panksepp, 1980; Hoebel & Novin, 1982). Instead some current concepts of the neural control of foo...
متن کاملGhrelin: a hormone regulating food intake and energy homeostasis.
Regulation of energy homeostasis requires precise coordination between peripheral nutrient-sensing molecules and central regulatory networks. Ghrelin is a twenty-eight-amino acid orexigenic peptide acylated at the serine 3 position mainly with an n-octanoic acid, which is produced mainly in the stomach. It is the endogenous ligand of the growth hormone secretagogue (GHS) receptors. Since plasma...
متن کاملSignals that regulate food intake and energy homeostasis.
Feeding behavior is critical for survival. In addition to providing all of the body's macronutrients (carbohydrates, lipids, and proteins) and most micronutrients (minerals and vitamins), feeding behavior is a fundamental aspect of energy homeostasis, the process by which body fuel stored in the form of adipose tissue is held constant over long intervals. For this process to occur, the amount o...
