举一反三
- Through which of the following structure does nerve fibers conduct nerve impulses? A: Myelin sheath B: Axolemma C: Neurofilament D: Synaptic vesicle
- Insulativity is a characteristic of excitation conduction on nerve fiber.
- Insulativity is a characteristic of excitation conduction on nerve fiber. A: 正确 B: 错误
- Oligodendrocytes make myelin, a fatty substance that insulates nerve axons and speeds the conduction of impulses along nerve fibers.
- Exciting conduction velocity of nerve fibers () A: is connected with the square of the diameter B: is connected with the diameter C: has nothing to do with the thickness of myelin sheath D: is unaffected by temperature E: is associated with the intensity of stimulation
