Lloyds pharmacy ventolin 1.сократительного термогенеза - production of heat as a result of reduction of skeletal muscles (any activity локомоторного the device; терморегуляционный a tone; холодовая a muscular shiver); Ciloslet At cooling there is an inflow increase афферентных nervous impulses from холодовых skin receptors in гипоталамус. As a result of it нейроны are raised and send through kernels of an average and oblong brain a stream эфферентных nervous impulses to мотонейронам a spinal cord which strengthen rhythmic импульсацию, going to skeletal muscles of a neck, a trunk and extremities. Originally it is shown in growth of tonic pressure of a muscle, reductions it thus does not make. At rather weak cooling in muscles at their visible rest there are single reductions of separate fibres that allows to raise the general теплопродукцию on 20 - 40 %. In терморегуляционный a tone muscles of a chin, a neck, the top humeral belt, a trunk, сгибатели extremities are consistently involved. It acceptance of the certain pose reducing the area of a surface of a body, contacting to environment speaks. At the further cooling when decrease in internal temperature of an organism begins, there are involuntary periodic reductions of skeletal muscles (холодовая a shiver). In this case the minimum mechanical work, and almost all metabolic energy in a muscle is made released in the form of heat. Теплопродукция a human body at холодовой a muscular shiver increases in 2 3 times and more.
