Final answer:
The synapse formed between pre-ganglionic and post-ganglionic neurons is a chemical synapse, where neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, initiating signal transmission.
Step-by-step explanation:
The synapse formed between pre-ganglionic and post-ganglionic neurons is a chemical synapse. In a chemical synapse, the pre-synaptic neuron releases neurotransmitter molecules into the synaptic cleft, which then bind to receptors on the post-synaptic neuron. This interaction initiates a change in the membrane potential of the postsynaptic cell, typically leading to signal propagation or inhibition.
During chemical synaptic transmission, various steps occur including the release of neurotransmitters from synaptic vesicles within the presynaptic neuron, the binding of these neurotransmitters to receptors on the postsynaptic neuron, and the subsequent response of the postsynaptic cell. This sequence of events results in the propagation of the nerve impulse across the synapse. When neurotransmitters bind to ligand-gated ion channels on the postsynaptic membrane, these channels open, allowing ions to flow into or out of the postsynaptic neuron, leading to either depolarization or hyperpolarization.
