第一节概论一、传出神经系统的分类传出神经是传导来自中抠的冲动,支配效应器官活动的神经。传出神经包括运动神经和植物神经两大类,而植物神经又包括交感神经和副交感神经两种。 1.运动神经从神经中枢发出后,中途不更换神经元,直接到达所支配的骨骼肌,因此无节前神经纤维和节后神经纤维之分。 2.植物神经植物神经包括①交感神经,节前神经元在胸1～12腰1～3段的脊髓侧角中,它们发出的纤维在交感神经节(包括交感神经链,
Introduction to the first section I. Classification of the outgoing nervous system The transmitted nerve is the nerve that conducts conduction from the middle pull and controls the activity of the organ. Outgoing nerves include motor nerve and autonomic two categories, while autonomic and sympathetic and parasympathetic two. 1. Motor Nerve issued from the nerve center, the midway does not replace the neurons, directly to the dominant skeletal muscle, preganglionic nerve fibers and postganglionic nerve fiber points. 2. Autonomic autonomic nerve including ① sympathetic, preganglionic neurons in the chest 1 to 12 lumbar 1 to 3 in the lateral horn of the spinal cord, they send the fibers in the sympathetic ganglia (including the sympathetic chain,
