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 is a neuron in Patient B’s spinal cord, which patient may have multiple sclerosis?

This is all I was given.

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...

The thickness of a single membrane is about 7 nm. A myelin sheath consists of multiple membranes produced by coils of Schwann cell or oligodendroglia cells. Suppose a myelin sheath results from 100 membranes stacked on top of each other. A) What is the specific capacitance of the myelin? B) If the myelin sheath is a right circular cylinder 1 mm long, what is its total capacitance? C) How much charge does it take to produce a voltage of -70...

28:Parkinson’s disease and multiple sclerosis are two disorders that directly affect glial cells. When glial cells are damaged, which of the following functions is most likely to be affected? A:Basic cell processes, such as cellular respiration. B:Receiving of neurotransmitters released by adjacent neurons. C:Transmission of electrical signals along the axon. D:Release of neurotransmitters by terminal buds. 29:If an event occurs periodically, but has a significant impact on the internal environment which method of homeostatic control is most likely? A:It is...

4. Multiple sclerosis (MS) is an autoimmune disease in which self-reactive T cells and antibodies attack neurological tissues in the brain. This disease is associated with HLA-DR2 and is ten times more frequent in women than in men. What type of molecule does the HLA-DR2 gene code for? What does it mean that MS is associated with HLA-DR2? Specifically, is this a causal relationship? What does it mean that MS is more frequent in women than in men? d. In...
