The mentality is the specific property of a brain consisting in reflexion of subjects and the phenomena existing out of us and irrespective of us of a material world. Sensations and perceptions are the necessary initial stage of our knowledge of and about an external world. The sensation is a process of reflexion in ЦНС separate properties of subjects and the phenomena of the objective reality directly influencing sense organs. Any sensation has quality, force, duration. Qualitative features of those or other sensations are called as their modality. Sensations give a material for more difficult forms of reflexion of the validity in consciousness (perceptions, thinking), i.e. are a source of all knowledge of the validity surrounding us. Motility of a gastroenteric path - one of the factors limiting speed and completeness всасывания of medical products. Rise in temperature of environment is perceived by thermal receptors, импульсация from them arrives in the centres гипоталамуса. In the answer there is a reflex expansion of vessels of a skin (owing to decrease sympathetic вазоконстрикторного a tone), as a result the skin blood-groove sharply amplifies also a skin gets red colour, еетемпература surplus of heat raises also dissipates from a surface of a body at the expense of thermal radiation, теплопроведения and конвекции. Blood comes back to internal areas of a body on the veins lying under the surface of a skin, passing the counterflow heat exchanger thanks to what the quantity of heat which it receives from arterial blood decreases. The affinity of these veins to a skin surface increases cooling of the blue blood which is coming back to internal areas of a body. At the person the maximum expansion of vessels of a skin from a condition of the maximum narrowing would reduce a combined value of a thermal protection of an integument on the average in time. Not all sites of a surface of a skin it is equivalent participate in теплоотдаче. Brushes of hands have special value, from them can be taken away to 60 % теплопродукции the basic exchange, though their area составляетлишь about 6 % from the general surface of a body. The snail has length of 3,5 mm that makes 2,5 curls. It is divided by two membranes: the basic and a membrane of Rejsnera on three courses or ladders: drum-type, average and vestibular (fig. 32). Vestibular and drum-type ladders at a top of a snail are connected among themselves through геликотрему. Both these ladders are filled перилимфой, similar on a chemical compound with a spinal liquid and containing it is a lot of sodium ions (about 140 mmol/l).
