Nervous Coordination: Nerve Impulses
Nervous Coordination: Nerve Impulses
- Myelinated neurons increase the speed of nerve impulse conduction.
- Saltatory conduction is the process by which electrical signals jump from one node of Ranvier to the next along a myelinated neuron.
- Resting potential is the state of a neuron when it is not transmitting signals.
- Action potential is the electric charge produced in a neuron when it transmits a signal.
- Various ion channels work together to establish resting and action potentials.
- The all-or-nothing response principle explains that an action potential either triggers completely or not at all.
- An action potential graph may be used to demonstrate this process, and frequency calculations might be required.
- The strength of the signal is determined by its frequency, not the degree of depolarisation.
