Ability to respond to nerve stimuli is called?

The ability to respond to nerve stimuli is irritability. In physiology, irritability describes how living tissue reacts to a stimulus carried by nerves, producing a response such as a muscle contraction or a glandular action. Elasticity is about how tissues stretch and recover their shape, not their nerve responsiveness. The buccinator is a specific cheek muscle, not a general property of tissue. A pacemaker refers to the control of heart rhythm (or the device that does), not to how tissues respond to nerve signals. So irritability best captures the concept of responding to nerve stimuli.
