Myelinated

Describe the contribution of passive electrical properties of membranes, to propagation of Action Potential along the myelinated axons. I know how action potential is generated, what myelinated axons are, but I am just confused about the active and passive properties of the membrane. ...

... each paragraph with a title and lay out the results that allow them to go to each conclusion. ie that they manage to transform the stem cells in myelinated neurons, and that they can help heal spine injury if transplanted shortly after injury. In fact i can say that if the style may not be great, ...

Hello, I need help please - I have been trying to find out the role of voltage gated channels in the conduction of a nerve impulse along a myelinated neuron and I cannot find a simple answer, can anyone help? Regards Sarah

... the amount of nuclei would indicate it is a smooth muscle. As far as I know, a peripheral nerve consists of axons of neurons which lack nuclei. Myelinated nerves are surrounded by nucleated Schwann cells, though. Also, taking into account the number of cells in that fibre I would go for a muscle, ...

... a depolarization of the membrane at one node almost immediately spreads passively to the next node. Thus, an action potential propagates along a myelinated axon by jumping from node to node, a process called saltatory conduction. This type of conduction has two main advantages: action potentials ...
