Vaccines saves lives, Over the years, vaccines have prevented countless cases of disease and disability, and have saved millions of lives.
Vaccines Protect Individuals, Families and Communities, Did you know that when you get vaccinated, you’re not only protecting yourself, but you are also protecting your family and your community from contagious and dangerous diseases?
Vaccines are Cost-Saving, Vaccine-preventable diseases can be very costly resulting in doctor’s visits, hospitalizations, and premature deaths.
Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
The best answer is <span>A. disease that can be spread to a person from another person, an animal, or an object. A communicable disease means it is easily transmitted or passed along. Hope this helped
