B) Axons often have branches near their tips that allow the neuron to communicate information to more than one target.

Question

Quizplus · Accepted Answer

Axons often have branches near their tips called axon collaterals which allow the neuron to communicate information to more than one target. Option A is false as myelinated neurons have an axon. Option C is false as axon terminals are responsible for sending information to other neurons or targets, not receiving information. Option D is false as myelinated axons are faster than unmyelinated axons due to the presence of nodes of Ranvier which allow for saltatory conduction.
