How do neurons communicate?
A) Terminal buttons plug into receptor sites on adjacent dendrites.
B) Neurotransmitters cross the synapse and bind with receptors on the postsynaptic dendrite.
C) Electric signals jump across the synapse to the adjacent neuron.
D) Chemicals released into the synapse are converted to neurotransmitters that bind with receptors.

Question

Quizplus · Accepted Answer

Neurons communicate through the release of neurotransmitters, which cross the synapse and bind with receptors on the postsynaptic dendrite of the adjacent neuron. This process is known as synaptic transmission. Option A is incorrect as terminal buttons are actually located on the axon terminals, which release neurotransmitters into the synapse. Option C is also incorrect as electric signals (action potentials) do not jump across the synapse, but instead, trigger the release of neurotransmitters. Option D is partially true, but the chemicals released into the synapse are not necessarily converted to neurotransmitters, as they may also include neuropeptides, hormones, or other signaling molecules.
