Question 1

Researchers have found that:

Accepted Answer

A)  in unmyelinated axons, positively charged ions flow down the axon at a very fast rate, causing regeneration of the action potential at each node. 
B)  when a nerve impulse reaches the axon terminal's button-like tip, the action potential "hops" over to the receiving neuron's dendrites. 
C)  throughout life, unused synaptic connections are pruned away as cells or their branches die and are not replaced. 
D)  in myelinated axons, the action potential at each point in the axon gives rise to a new action potential at the next point.
