Excitability - Glossary Term Illustration

Excitability

Excitability is the ability of a muscle cell to change in membrane conductance as a response to stimulation. For example, muscle cells are specialized to react to a change in membrane potential with contraction, whereas nerve cells are specialized to propagate a change in membrane potential along their axons and communicate that message to other tissues via neurotransmitters. 1.
