Detailed explanation-1: -The presynaptic terminal is at the end of an axon and is the place where the electrical signal (the action potential) is converted into a chemical signal (neurotransmitter release). The postsynaptic terminal membrane is less than 50 nanometers away and contains specialized receptors.
Detailed explanation-2: -The axonal terminals are specialized to release the neurotransmitters of the presynaptic cell. The terminals release transmitter substances into a gap called the synaptic cleft between the terminals and the dendrites of the next neuron.
Detailed explanation-3: -Neurotransmitters are released from synaptic vesicles in presynaptic neurons in response to neural activity, diffuse across the synaptic cleft, and bind specific receptors in order to bring about changes in postsynaptic neurons.
Detailed explanation-4: -A message travels from the dendrites through the cell body and to the end of the axon. into the synapse. The neurotransmitters carry the message with them into the synapse. The synapse is the space between the axon of one neuron and the dendrites of another neuron.
Detailed explanation-5: -The axon terminal is important in cell to cell communication through the neurotransmitters it releases into the synaptic cleft. The neurotransmitters that exit the neuron relay signals to the next target cell.
