Oligodendrocytes make myelin, a fatty substance that insulates nerve axons and speeds the conduction of impulses along nerve fibers.
举一反三
- The reason for rapid conduction of impulses along myelinated nerve fibers is that they have( ) A: long axons B: thick axons C: many synaptic vesicles in the axons D: clefts of Schmidt and Lantermann E: nodes of Ranvie
- In myelinated nerve fibers nerve impulses() A: occurs along the entire axolemma B: jump from node to node C: jump from internode to internode D: occurs along the Schwan cells E: occurs along the oligodendrocytes
- Through which of the following structure does nerve fibers conduct nerve impulses? A: Myelin sheath B: Axolemma C: Neurofilament D: Synaptic vesicle
- Oligodendrocytes make myelin, a fatty substance that insulates nerve axons and speeds the conduction of impulses along nerve fibers. A: 少突胶质细胞能制造髓磷脂。髓磷脂是一种脂类物质，能使轴突绝缘并能使冲动沿着神经纤维快速传导。 B: 少突胶质细胞能制造髓磷脂。髓磷脂是一种能使轴突绝缘并能使冲动沿着神经纤维快速传导的脂类物质。 C: 少突胶质细胞能制造髓磷脂。髓磷脂是一种脂类物质，它包裹着轴突, 能使冲动沿着神经纤维快速传导。 D: 少突胶质细胞能制造包裹着轴突使冲动沿着神经纤维快速传导的一种脂类物质 — 髓磷脂。
- The axons and dendrites that are coated with a myelin sheath are called ( ). A: Neurite B: Nerve C: Nerve ending D: Nerve fiber
