Selected hormonal and neurotransmitter mechanisms regulating feed intake in sheep

Selected hormonal and neurotransmitter mechanisms regulating

Neural 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...

Negative Feedback Mechanisms Regulating Neurotransmitter

Homeostasis is an indispensable phenomenon in the maintenance of living organisms. Genetic defects which disrupt negative feedback processes can impact homeostatic regulation, potentially resulting in disease. To uncover the molecular mechanisms governing these and other diseases potentially related to defective homeostasis, I used the Drosophila neuromuscular junction as a model system. I char...

Mechanisms regulating feed intake, energy expenditure, and body weight in poultry.

To achieve energy balance and maintain a constant BW, changes in feed intake and energy expenditure must be coordinated and tightly regulated. This may not hold true for some poultry species intensively selected for such economically important traits as growth and meat production. For example, the modern commercial broiler breeder does not adequately control voluntary feed intake to meet its en...

Hormonal and Neural Mechanisms Regulating Hormone Steroids Secretion

Hormonal and neural signals participate in regulating the synthesis and release of steroid hormones from the adrenals, ovaries and testicles. Hormonal signals arise from the hypothalamus, pituitary, thyroid, thymus, adipose tissue, as well as from the adrenals, ovaries and testicles. Neural signals originating in the hypothalamus and other regions of the central and peripheral nervous system mo...
