Study Notes
Nerve Impulse Transmission
- A nerve impulse is an electrical signal traveling along a neuron.
- The impulse originates from ion movement, causing changes in electrical charge.
- At rest, the neuron's intracellular space is negatively charged, and the extracellular space is positively charged. This is called the resting potential.
- Nerve impulses are weak electric currents, similar to waves.
