Answer :

Electrical signals in excitable cells are transmitted by voltage-gated ion channels (VGICs).

The required details about voltage-gated ion is mentioned in below paragraph.

Since the transmission of action potentials in neurons is impacted by small-molecule regulation of VGICs, the central nervous system's activity can also be changed. The significance of voltage-gated channels, which are crucial for producing action potentials.  Action potentials are produced by voltage-gated Na+ and K+ channels in neurons and skeletal muscle cells. A neuron's action potential is what causes a nerve impulse, whereas a muscle cell's action potential causes skeletal muscle to contract.

Electrical signals are produced in cell membranes by voltage-gated ion channels.
