They need to have a q system perspective in order to work.
Answer:
Some People Stop Breathing For A Few Seconds. You can die from drinking too much water. People have died from eating too much. Your fingernails grow four times as fast as your toenails. Babies are born with 300 bones, but adults have 206. Eyelashes last about 150 days. The heart circulates blood through your body about 1,000 times each day.
Explanation:
The abiltiy to do things with you body that most people cant, such as bending your back without breaking it
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).
