The action mechanism нейролептиков is based on their oppressing action on ретикулярную a formation and its activating influence on a bark of the big hemispheres, and also on interaction нейролептиков with media even systems of a brain: adren - serotonin - holin - ГАМКи especially with дофаминергическими. buy atarax Аксоны рецепторных cages, having united in a bunch, go to an olfactory bulb where there are the second нейроны. Fibres of cages of an olfactory bulb form the olfactory path having triangular expansion and consisting of several bunches. The olfactory bulb generates the rhythmic impulses which frequency changes at inflation in a nose of various odorous substances. Bunches of an olfactory path pass in various structures of a brain: миндалину, гипоталамус (is responsible for an emotional component of olfactory sensations), ретикулярную a formation, an orbito-face-to-face bark, препериформную a bark and периформную a share, in an olfactory bulb противоположнойстороны. The central department of the olfactory analyzer is in a forward part of a pear-shaped share in the field of a crinkle of a sea horse (гиппокампа). Odorous substances are perceived also by the free terminations of fibres of a trigeminal nerve (V steam of craniocereberal nerves), located in mucous a nose. So, substances with a pungent smell (ammonia) are perceived by the terminations of a trigeminal nerve and can cause respiratory standstill or protective reflexes (чихание). These reflexes become isolated at level of an oblong brain. Besides хиломикронов in энтероцитах are formed липопротеины very low density which also get to lymphatic vessels. As fats basically are soaked up in a lymph in some hours after food intake from всасывания fat the lymph gets white colour, reminding milk (lacteal juice).
