Answer:
The main difference between diagnoses is that anorexia is a syndrome of self-starvation involving significant weight loss of 15 percent or more of ideal body weight, whereas patients with bulimia are, by definition, at normal weight or above.
Explanation:
Individuals with bulimia often do eat throughout their daily lives, however, it may be much less than the average person eat daily, or they may go long periods of time without eating anything (say 2-3 days), then binge eat. They also find themselves with the compulsive need to purposefully induce their gag reflex, causing them to throw up. Whereas people with anorexia simply do not eat or eat very little, and sometimes have the need to exercise excessively. Bulimic people may often appear very tired, with dark circles under the eyes, or their teeth may be very yellow or look unkempt (due to the throwing up). Anorexic people appear very skinny, some may seem almost "skeleton" like, they're typically short, and wear over-sized clothing to cover themselves.

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).
