b. Label the figure indicating the steps involved in neural transmission (use the key terms provided in the box below the figure) 1 Synthesizing enzymes Neurotransmitter precursors Vesicle Neurotransmitter molecules that leak from their vesicles are destroyed by enzymes. Degrading enzymes 4 E Released neurotransmitter molecules bind with autore- ceptors and inhibit subsequent neurotransmitter release. 6. Autoreceptor Postsynaptic receptor A. Neurotransmitter molecules are stored in vesicles B. Released neurotransmitter molecules are deactivated by reuptake C. Action potentials cause vesicles to fuse with the presynaptic membrane and release their neurotransmitter molecules into the synaptic cleft D. Neurotransmitter molecules are synthesized from precursors under the influence of enzymes E. Released neurotransmitter molecules bind to postsynaptic receptors

If an ANS action potential were to start at the tip of arrow A and travel to the small intestine (i.e. its effector) to decrease its activity, name all cells and neurotransmitters in order that would be used to transmit that signal. ii.

Good morning Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited. Be sure to include the phases of an action potential, the channels involved, and the importance of an action potential. Thank you
