Which of the following describes how neurons use neurotransmitters to communicate with one another?
At synapses, dendrites release neurotransmitters that are recognized by proteins on axons.
At synapses, axons release neurotransmitters that are recognized by proteins on dendrites.
Axons fuse with dendrites to produce a continuous cellular body that allows neurotransmitters to flow from one neuron to another.
The axons of one neuron connect to the axons of another neuron to relay information through neurotransmitter release.

Answer 1
