Terminal Buttons
Terminal buttons are structures at the end of an axon that contain synaptic vesicles filled with neurotransmitters. When an action potential reaches these buttons, it triggers the vesicles to release their neurotransmitters, facilitating communication with other neurons across the synaptic cleft.

A neurological disorder is characterized by a significant slowing of the electrical signal as it travels down the long extension of a nerve cell, leading to symptoms like muscle weakness and poor coordination. Given this information, which part of the nerve cell is most likely deteriorating?

A specific neurotoxin is introduced into a neural pathway. Its sole effect is to prevent the structures at the very end of an axon from releasing their stored chemical messengers. What would be the most immediate and direct consequence of this toxin on the communication process between two connected neurons?
