Nerve and muscle cells are able to conduct action potentials because they have voltage-gated ion channels, which allow for rapid changes in ion permeability and the sudden influx of positively charged ions, such as sodium, that generate the action potential. While nerve and muscle cells are polarized and have resting membrane potentials, and are impermeable to certain ions (such as sodium in the case of resting muscle cells), the presence of voltage-gated ion channels is crucial for the initiation and propagation of action potentials.
