ACh is released into the synaptic cleft.
Sodium pumps into the sarcolemma.
The muscle contracts.
What is the name of the component that houses the neurotransmitters?
Synaptic cleft
Acetylcholine
Receptors
Synaptic vesicles
Once ACh binds to receptor cells on the sarcolemma, what takes place?
Sarcolemma becomes temporarily permeable to sodium.
The muscle contracts.
Calcium is pumped into the axon terminal.
Synaptic vesicles move to the end of the terminal.
The neuromuscular junction is created when the nerve cell reaches the ___.

Sarcolemma
Myofibril
Once sodium is pumped into the sarcolemma, what happens?
Action potential is transferred to the sarcolemma to start the process of contraction.
The process ends and ACh breaks down.
Calcium is pumped into the axon terminal.
ACh is released into the synaptic cleft.
Once the action potential reaches the end of the axon terminal what takes place?
ACh is released into the synaptic cleft.
Calcium is pumped into the sarcolemma.
Calcium is pumped into the axon terminal.
The muscle contracts.
