The somato-vegetative reflex is an organism's answer to physical stress, resulting from the action of miscellaneous stimuli on extero- and proprioreceptors. It is realized in two types of responses of alarm groups: Response to a stressor with superiority of the parasympathetic system. This is not often present and manifests as decrease in pulse, heart stroke volume and pressure. An adrenergic response to a stressor, realized sequntionally in time periods. The neurogenic phase and humoral phase connected with the ejection of amine from the core of the suprarenal gland are separately distingiushed in this type of response. Significant increase in blood pressure, vascular resistance, augmentation of flow of blood in the aorta and tachycardia were observed in these two phases to a considerable extent. An important role in this reflex is performed by the limbic system, whose activation causes a circulation of stimulation in the Papez emotive district, which lies at the basis of the appearance of vegetative symptoms of emotions. Knowledge of the mechanism of this reflex is important, as it may play an important role, without the participation of the consciousness (anesthesia) in diagnosing pain in miscellaneous surgical and dental procedures and sharp pain syndromes, as well as the prevention of the occurrence of this reflex and its hemodynamic repercussion.
躯体-植物性反射是机体对物理应激的反应，由各种刺激作用于外感受器和本体感受器引起。它通过两种警报反应类型实现：副交感神经系统占优势的应激源反应。这种情况不常出现，表现为脉搏、心搏量和血压下降。对应激源的肾上腺素能反应，在不同时间段依次发生。在这种反应类型中，分别区分出与肾上腺髓质胺类物质释放相关的神经源性阶段和体液性阶段。在这两个阶段中，观察到血压显著升高、血管阻力增加、主动脉血流量增加和心动过速。边缘系统在这种反射中起重要作用，其激活导致帕佩兹情感区的刺激循环，这是情感植物性症状出现的基础。了解这种反射的机制很重要，因为它可能在各种外科和牙科手术及急性疼痛综合征的疼痛诊断中，在无意识（麻醉）参与的情况下发挥重要作用，以及预防这种反射的发生及其血液动力学影响。
