What's the difference between myelinated and unmyelinated neurons? What's the effect of myelin on nerve stimulus transmission? Transmission speed of Nerve A: 19 m/sec. Transmission speed of Nerve B: 45 m/sec. Which one is myelinated? Explain why. Multiple sclerosis is a type of disease where the myelin sheath of nerve cells in the brain and spinal cord is 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?

Multiple sclerosis (MS) is a disorder where the body's immune system attacks and destroys the myelin surrounding nerves. The consequences of this are that: A) the cell bodies of nerve cells cannot be stimulated because sodium receptors are not functioning properly. B) The axons of the neurons are less effective in relaying messages because their insulating sheaths have been damaged. C) Neurotransmitter molecules in terminal knobs are broken down and cannot relay an impulse to the next neuron. D) Receptor sites on the post-synaptic membrane have been damaged and can no longer be stimulated sufficiently to initiate an action potential in the next neuron.
