Synaptic transmission is terminated primarily through the reuptake of neurotransmitters by the presynaptic neuron, where they are repackaged into vesicles or broken down by enzymes. Additionally, neurotransmitters can be degraded by specific enzymes in the synaptic cleft, such as acetylcholinesterase for acetylcholine. Another mechanism involves the diffusion of neurotransmitters away from the synaptic cleft, reducing their concentration and effect on the postsynaptic receptors. Collectively, these processes ensure that the signal is brief and precisely regulated.
Yes
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
No, synaptic transmission is chemical, not electrical.
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 small space separating pre and post-synaptic neurons is called the synaptic cleft. This cleft allows for the transmission of chemical signals, known as neurotransmitters, from the pre-synaptic neuron to the post-synaptic neuron to occur. The neurotransmitters are released by the pre-synaptic neuron and bind to receptors on the post-synaptic neuron to transmit the signal.

Acetylcholine (ACh) is released from the presynaptic neuron into the synaptic cleft. It then binds to ACh receptors on the postsynaptic neuron, causing ion channels to open and allowing for the transmission of the nerve impulse. Any remaining ACh is broken down by the enzyme acetylcholinesterase, ensuring that the signal is quickly terminated.
Synaptic vesicles are found in the axon terminals of nerve cells.
