Primer Energy homeostasis and body weight
That body weight is regulated has been evident to physiologists for many years. When access to food is restricted, animals increase their desire for food and indulge heartily when food reappears. To conserve energy during caloric restriction, appetite is regulated and the overall metabolic rate declines. Conversely, to resist obesity, forced overfeeding suppresses appetite and increases metabol...
متن کاملEffects of ghrelin in energy balance and body weight homeostasis.
Ghrelin is a gut peptide composed of 28 amino acids mostly secreted in the gastric fundus mucosa. It was isolated and described in 1999 by Kojima et al. and only three years later its specific receptor, GHSR1a, was also identified. Ghrelin, the endogenous ligand for the GH secretagogue receptor, is the only peripheral orexigenic hormone that activates the receptors to be found especially in the...
متن کاملCadm2 regulates body weight and energy homeostasis in mice.
OBJECTIVE Obesity is strongly linked to genes regulating neuronal signaling and function, implicating the central nervous system in the maintenance of body weight and energy metabolism. Genome-wide association studies identified significant associations between body mass index (BMI) and multiple loci near Cell adhesion molecule2 (CADM2), which encodes a mediator of synaptic signaling enriched i...
متن کاملEnergy Homeostasis in Monotremes
In 1803, the French anatomist Étienne Geoffroy Saint-Hilaire decided that the newly described echidna and platypus should be placed in a separate order, the monotremes, intermediate between reptiles and mammals. The first physiological observations showed monotremes had low body temperatures and metabolic rates, and the consensus was that they were at a stage of physiological development interm...
متن کاملBody sodium and volume homeostasis.
MAINTENANCE OF A “MILIEU INTERIEUR,” which allows our cells to function away from the ancient sea, is one of the most important functions of the body. Maintenance of constant extracellular osmolarity and sodium concentration depends on a precise balance between intake and excretion of sodium and water. Intakes of water and sodium are governed by an urge driven by the lack of these substances, b...
