What is the direction of electrical impulse propagation along the axon?
What is the direction of electrical impulse propagation along the axon?
- Lateral direction
- Bidirectional
- Anterograde direction (correct)
- Retrograde direction
Why can the electrical impulse only propagate in an anterograde direction?
Why can the electrical impulse only propagate in an anterograde direction?
- Because the entire axon is depolarized
- Because the axon is not depolarized
- Because the upstream region is depolarized and refractory (correct)
- Because the downstream region is depolarized
What is the state of the upstream region of the membrane?
What is the state of the upstream region of the membrane?
- Polarized
- Depolarized and refractory (correct)
- Hyperpolarized
- Hypopolarized
What is the consequence of the upstream region being depolarized and refractory?
