Answer:
Well,
Explanation:
Depression can affect ones health in many ways, including social health. Depression can create social anxiety or the fear of talking to people because you think you're gonna do or say something that may make you look weird or out of place.
Depression also lowers your self-confidence, so you won't look as confident in yourself while in a conversation which may make you vulnerable to bullying, or just really sensitive about the things people say about you, even if it's not a big deal.
If you, a friend, or a family member is suffering with depression, please don't hesitate and tell someone, talking about it may help relieve the pain.
Do you have any choices ?
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).
