Consider a myelinated nerve with axon of radius, a = 10 micrometers, and Myelin sheath of thickness b = 0.4a. A) Calculate the space constant. B) Assume that a potential change of ∆V = 10mV is required to initiate an action potential, and that the distance between two nodes of Ranvier is D = 200a. If the maximum potential change is ∆V = 100mV, how many nodes of Ranvier can be triggered

the specific values are right in the question if you actually read it

Multiple sclerosis is a type of disease where myelin sheath of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to transmit signals, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems. Specific symptoms can include double vision, blindness in one eye, muscle weakness, and trouble with sensation or coordination. If Nerve a is a neuron in Patient A’s and nerve B...

Electron micrographs of human nerve fibers show 10-15 layers of membranous myelin sheath. Upon close examination, these membranes are particularly rich in sphingolipids specially the glycosphingolipids. What could be the reason why these types of lipids abound in human myelin?

Explain: (a) Myelinated axon: Some neurons, like most of the neurons in human body, have myelinated axons; the axons are wrapped around with segmented myelin sheaths. When compared with unmyelinated axons of the same axon diameter, the neural signal transmission speed along myelinated axons is much faster than that along unmyelinated axons. Qualitatively and briefly explain why. (b) Hopfield model: Hopfield model can be considered as a form of neural net algorithm of retrieving information from a large database. When...
