Reminyl, known chemically as galantamine, works like the nation's three other Alzheimer's medications. It modestly slows cognitive (mental ability) decline by inhibiting the breakdown of acetylcholine, a brain chemical vital for nerve cells to communicate, by the enzyme acetylcholineesterase. -What effect would Reminyl have on a neuron's ability to release neurotransmitters?

The myelin sheath around an axon is continuous.

The division of the peripheral nervous system that carries signals to voluntary muscles is the
