Here is a step-by-step analysis of each item in the matching question, considering the presynaptic vs. postsynaptic roles.
Item 1: Action potential travels away from the synapse via this neuron.
- Provided correct match: postsynaptic neuron.
- Why this would be considered correct in the given key: The description emphasizes movement away from the synapse, which involves the neuron that propagates the signal away from the synapse toward the next cell. In typical neurophysiology, this is the presynaptic neuron, since it conducts the impulse toward the synapse for transmission to the next neuron. The key stating postsynaptic here appears to mislabel the directionality, unless the context ......Login to view full explanation登录即可查看完整答案

Which of the following explains why one-way synaptic transmission occurs?
The following are events in the transmission of a signal at a chemical synapse. Neurotransmitter binds with receptors associated with the postsynaptic membrane. Calcium ions rush into neuron's cytoplasm. An action potential depolarizes the membrane of the presynaptic axon terminal. The ligand-gated ion channels open. The synaptic vesicles release neurotransmitter into the synaptic cleft. Which sequence of events is correct?
