QuestionAnatomy and Physiology
List the steps of chemical synaptic transmission in 7 steps or less. Where do each of these steps occur within a synapse?
Action potential arrives at the presynaptic terminal.
Voltage-gated calcium channels open.
Calcium ions enter the presynaptic neuron.
Synaptic vesicles fuse with the presynaptic membrane.
Neurotransmitters are released into the synaptic cleft.
Neurotransmitters bind to receptors on the postsynaptic membrane.
Postsynaptic potential is generated.

Step 1Here's a detailed explanation of chemical synaptic transmission with precise LaTeX formatting:
Step 2: Action Potential Arrival
- Location: Presynaptic terminal - The action potential travels down the axon and reaches the presynaptic terminal - This electrical signal triggers the subsequent chemical transmission process
Final Answer
Chemical synaptic transmission is a precisely coordinated process involving seven key steps, occurring across different regions of the synapse, ultimately enabling communication between neurons through chemical signaling.
