Question

Which of the following indicates the correct order of information traveling between two neurons?

a. Synaptic cleft, dendrite terminal, axon terminal cross out
b. Synaptic cleft, axon terminal, dendrite terminal cross out
c. Axon terminal, synaptic cleft, dendrite terminal cross out
d. Dendrite terminal, synaptic cleft, axon terminal

Answer 1

The proper order of information traveling between two neurons starts at the axon terminal, moves through the synaptic cleft, and ends at the dendrite terminal of the postsynaptic neuron. The correct option is c.

Step-by-step explanation:

The correct sequence of information transfer between two neurons is indicated by option c. This involves the process of synaptic transmission, which occurs as follows:

1. A signal is generated and travels down the axon of the presynaptic neuron.
2. When the signal reaches the axon terminal, it triggers the release of neurotransmitters into the synaptic cleft, which is the gap between the two neurons.
3. The neurotransmitters then cross the synaptic cleft and bind to receptors on the dendrite terminals of the postsynaptic neuron.

This initiates a new signal within the postsynaptic neuron, completing the communication process between the two neurons. Option c. is the correct one.
