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).
Answer:
The three types of empathy that psychologists have defined are: Cognitive, Emotional, and Compassionate. As an aside, it's worth noting that empathy is a relatively new idea and still being defined by social and cognitive psychologists.
A nurse is preparing to administer haloperidol (haldol) 5 mg im to a client. available is haloperidol 20 mg/ml. In ml should the nurse administer is

Answer:
Power is a combination of strength & speed: Muscular Power = Strength x Speed. In basketball activities, power can be seen when an athlete jumps and is also in the explosive acceleration needed in transition. ... This can be overall speed of a player when sprinting or hand speed when a player is trying to steal a ball.
