I have never heard of the term 'transmission zone' (which may be someone's personal name for what I'm about to explain) but neurons send their chemical signals across what is known as a synapse, the region where the axon of one neuron meets up with another neuron (most often a dendrite). The space between these two neurons (the non-neuron space in the synapse) is called the synaptic cleft. Through this space, neurotransmitters pass through and act on the receiving neuron once they reach it.

The structure in the neuron that accelerates the transmission of the action potential is called the myelin sheath.
At a synapse, transmission typically occurs from the presynaptic neuron to the postsynaptic neuron. The presynaptic neuron releases neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic neuron's membrane, facilitating the transmission of signals. This unidirectional flow is essential for proper neuronal communication and signal processing in the nervous system.
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
Synaptic transmission, also called neurotransmission, refers to the process wherein neurotransmitters are released by a neuron to activate the receptors of another neuron. Communication between two nerve cells is accomplished by synaptic transmission.

The "Tigger zone" in a unipolar neuron is the initial segment of the axon where action potentials are generated. Here, graded potentials from the dendrites accumulate and if they reach a certain threshold, an action potential is triggered.
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
During an action potential in a neuron, there is a rapid change in electrical charge across the cell membrane. This change allows for the transmission of signals along the neuron.
