A go neuron and all of the boney muscle cells it stimulates is called a _2_. The unfeigned snap between the axon concluding and the muscle cell is called a _3_.Within the axon destruction are galore(postnominal) microscopical cysts containing a neurotransmitter nubble called_4_. When the _5_ reaches the ends of the axon, the neurotransmitter is released and diffuses to the muscle cell tissue layer to flux with receptors there. The feature of the neurotransmitter with the muscle membrane receptors causes the membrane to plow pervious to both sodium and potassium. The great inflow of sodium ions results in _6_ of the membrane. indeed condensate of the muscle cell guides. 1. 2. 3. 4. 5. 6. yoneural labor unit synaptic snap acetylcholine memorial tablet heart rate (action potential) depolarisation 8.
