Definitions
the neurotransmitter at the neuromuscular junction
What is acetylcholine?
is a signal sent down a motor neuron
What is an action potential?
acetylcholine receptors are located along here
What is junctional folds?
the gap between the neuron and muscle
What is the synaptic cleft?
these sacs release acetylcholine into the synaptic cleft
What is synaptic vesicles?
is the process where cells export neurotransmitters by fusing intracellular vesicles with the plasma membrane
What is exocytosis?
an enzyme that breaks down acetylcholine
What is acetylcholinesterase (AChE)?
as the action potential travels down the axon terminal this is released into the neuron
What is calcium (Ca2+)?
acetylcholine receptors are this type of channel
What is ligand-gated cation channels?
the process by which an action potential travels along the membrane of a neuron or muscle cell
What is propagation?
this ion rushes into the muscle when acetylcholine receptors open
What is sodium (Na+)?
toxin associated with tetanus blocks neurotransmitter release at inhibitory synapses, leads to uncontrollable muscle spasms
What is tetanospasmin toxin?
