NSC 3361 Exam 1 Questions and Answers All Correct Sequence of transmission at chemical synapse - Answer-1. Action potential travels down axon to axon terminal. 2. Voltage-gated calcium channels open and Ca2+ enters. 3. Synaptic vesicles fuse with membrane and release transmitter into the cleft. 4. Transmitter binds to post-synaptic receptor, causing EPSP or IPSP. 5. May bind to the presynaptic autoreceptors, decreasing release. 6. Neurotransmitter is inactivated by degradation or reuptak...

BIO 181 (Capco ASU) Exam 3 (Final Exam) Questions with Verified Solutions Briefly explain why the action potential flows only from the axon hillock to the terminal web. The action potential originates from the axon hillock which initiates the flow of the action potential because of the presence of higher density voltage-gated ion channels. Draw a neuron, and label all the parts as described in lecture. Draw an action potential in the axon of a neuron and indicate which ions flow int...
