What are the gaps between neurons called?

The correct answer identifies the gaps between neurons as synapses. A synapse is the specialized junction where communication occurs between two neurons, allowing for the transmission of signals. This communication is crucial for the functioning of the nervous system, as it facilitates the transfer of information through neurotransmitters released from the presynaptic neuron into the synaptic cleft, where they interact with receptors on the postsynaptic neuron.

In contrast, axons are the long, slender projections of neurons that carry electrical impulses away from the cell body, while dendrites are the branched extensions that receive signals from other neurons. Myelin sheaths are the protective coverings that insulate axons, helping to speed up the transmission of electrical signals, but they do not represent the gaps between neurons. Understanding these terms helps clarify the specific role each component plays in neuronal communication.
