Medical Definition of Excitable cell
1.
| A cell in which the membrane response to depolarisations is nonlinear, causing amplification and propagation of the depolarisation (an action potential). Apart from neurons and muscle cells, electrical excitability can be observed in fertilized eggs, some plants and glandular tissue. Excitable cells contain voltage gated ion channels.
