Show answer & explanation
Correct answer: A
Synaptic transmission usually occurs when neurotransmitters (chemicals) are released from the presynaptic neuron, diffuse across the synaptic cleft, and bind to receptors on the postsynaptic neuron. Therefore, transmission across most synapses is primarily a chemical process . Important Points (English) Synaptic transmission occurs at the junction between two neurons called a synapse .
The neuron sending the signal is the presynaptic neuron .
The neuron receiving the signal is the postsynaptic neuron .
Transmission usually happens through neurotransmitters (chemical substances) .
Neurotransmitters are released from the presynaptic neuron .
They diffuse across the synaptic cleft (small gap between neurons).
Neurotransmitters bind to specific receptors on the postsynaptic neuron.
This binding generates a new electrical signal in the postsynaptic neuron.
Hence, most synapses use chemical transmission , not electrical.
Chemical synapses allow signal amplification, modulation, and direction control .
