Study Notes

Factors Affecting Action Potential

  • The primary factor affecting the speed of action potential is the myelination of the axon.

Types of Potentials

  • A hyperpolarizing potential makes it harder to initiate a neural message.

Chemical Synapse

  • The opening of calcium channels in the synaptic bulb during a chemical synapse is triggered by an action potential.

Graded Potential

  • Potassium ions are involved in a positive feedback loop during the generation of graded potential.

Action Potential Amplitude

  • The amplitude of an action potential remains constant, it does not change.
