Presynaptic Terminal
Synaptic vesicles contain Neurotransmitter (NT) =
Ca2+ channels open in reaction to traveling down the , which allows Ca2+ into the . This then causes to enter the .

Ca2+ channels open in reaction to traveling down the , which allows Ca2+ into the . This then causes to enter the .
Synaptic vesicles contain Neurotransmitter (NT) = Acetylcholine (Ach)
NT = Molecule released by presynaptic terminal and stimulates (or inhibits) a postsynaptic cell
Ach always stimulates a skeletal muscle fiber
Ca2+ channels open in reaction to Action Potential traveling down the Motor Neuron Plasma Membrane, which allows Ca2+ into the Presynaptic Terminal. This then causes Exocytosis of Ach into the Synaptic Cleft.
