What is the point of contact between the axon of one neuron and a dendrite or cell body of another neuron called?

The correct answer is the synapse, which is the junction that connects two neurons and allows them to communicate with each other. At this point of contact, the axon terminal of one neuron meets either the dendrite or the cell body of another neuron. This structure is essential for transmitting signals within the nervous system, as it is at the synapse where the transfer of information occurs.

In the context of neurotransmission, once an electrical signal reaches the axon terminal, it prompts the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the receiving neuron, facilitating the continuation of the signal. Understanding the synapse is fundamental in grasping how information is processed and relayed in the nervous system.
