一、传出神经系统的分类、递质和受体、生理功能、药物的基本作用和药物分类的概况如何? 传出神经系统包括植物神经和运动神经四大类。植物神经又分为交感神经和副交感神经,主要支配心脏、平滑肌和腺体等效应器的活动。不论交感或副交感神经都有神经节,中枢发出的神经纤维(节前纤维)的末梢终止于神经节,神经节细胞发出的纤维(节后纤维)的末梢分布到效应器。运动神经支配骨骼肌,它没有神经节,中枢发出的纤维直达骨骼肌。当神经冲动到达神经末梢时,末梢释放一种化学物质叫递质或介质,作用于下一级神经元或效应器 First, the outgoing nervous system classification, transmitter and receptor, physiological function, the basic role of drugs and drug classification of the general situation? Out of the nervous system, including autonomic and motor nerve four categories. Autonomic nerve is divided into sympathetic and parasympathetic, mainly dominate the heart, smooth muscle and gland and other effector activity. Regardless of sympathetic or parasympathetic ganglion, the central nerve fibers (preganglionic fibers) end in the ganglion, the ganglion cells emitted fibers (posterior fibers) of the distal distribution to the effector. Motor nerve innervating skeletal muscle, it does not have ganglia, central issued by the fiber directly to skeletal muscle. When the nerve impulses reach the nerve endings, the terminal release of a chemical called neurotransmitter or mediator, acting on the next level of neurons or effectors
