What are the 4 steps of an action potential?
How action potential works step by step?
How does an action potential work for dummies?
What are the 5 steps of an action potential?
How does action potential work in a neuron?
What are the 7 steps in the generation of an action potential?
|STEP 1||Threshold stimulus to -55mv||Stimulus|
|STEP 4||At +30mv, Na channels close and K ions channels open||K ions|
|STEP 5||K floods out of the cell||Out of cell|
|STEP 6||Hyperpolarization to -90mv||Hyper|
|STEP 7||K channels close and tge resting potential is re-established at -70||Re-established|
What are the 3 phases of an action potential?
How does an action potential propagate?
How does depolarization occur?
What happens during depolarization in an action potential?
How does a neuron return to resting potential?
Why does depolarization cause contraction?
The opening of sodium channels causes depolarization of the skeletal muscle. The action potential from the motor neuron also travels through the T-tubules. It causes the release of Ca2+ ions from the sarcoplasmic reticulum. Thus, contraction of skeletal muscle occurs.
