Final answer:
The point of connection between two communicating neurons is known as the synapse, which can be a chemical or electrical connection facilitating communication between neurons.
Step-by-step explanation:
The point of connection between two communicating neurons is called the synapse. This connection can be either a chemical synapse or an electrical synapse. In a chemical synapse, a neurotransmitter diffuses across a very short distance known as the synaptic cleft to transmit information from one neuron to the next. In contrast, an electrical synapse involves the direct flow of ions through channels that span the adjacent cell membranes, allowing for communication between the cells.
The neuron transmitting the signal in a synaptic connection is referred to as the presynaptic neuron, while the neuron receiving the signal is called the postsynaptic neuron. Synapses are essential for neuronal communication, and they typically form between axon terminals and dendritic spines, although synapses can also occur between axons, dendrites, or directly onto the cell body of another neuron.
