The end of the axon where it contacts a target is called the - Answer✔️✔️-
axon terminal
Neurotransmitter is released into the synaptic gap by - Answer✔️✔️-
exocytosis
Exocytosis of neurotransmitter from the axon terminal is triggered by an
increase in the intracellular concentration of - Answer✔️✔️-Ca2+
The neurotransmitter released into the synaptic gap reaches the target cell
by - Answer✔️✔️-diffusion
At the target, neurotransmitter - Answer✔️✔️-binds to receptor proteins,
causes membrane channels to open or close, causes a change in membrane
potential
You have just observed that each action potential in a burst can trigger
additional neurotransmitter release. If calcium ions are removed from the
extracellular solution, what will happen to neurotransmitter release at the
axon terminal? - Answer✔️✔️-there will be more neurotransmitter release
