Microscopic gaps between the neuron endings are called__________?
Correct answer: B. Synapses
- A. Transmitters
- B. Synapses
- C. Pores
- D. Nodes
Explanation
The microscopic gap between the ending of one neuron and the next cell is called a synapse, more precisely the synaptic cleft. Students may choose a node, but nodes are gaps in the myelin sheath along an axon, not gaps between neuron endings.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
