Researchers have found that:

• A)in myelinated axons,the action potential at each point in the axon gives rise to a new action potential at the next point.

• C)throughout life,unused synaptic connections are pruned away as cells or their branches die and are not replaced.
• D)when a nerve impulse reaches the axon terminal's button-like tip,the action potential "hops" over to the receiving neuron's dendrites.
