What's the difference between excitability and irritability?
Excitability
Definition:
(n.) The quality of being readily excited; proneness to be affected by exciting causes.
(n.) The property manifested by living organisms, and the elements and tissues of which they are constituted, of responding to the action of stimulants; irritability; as, nervous excitability.

Irritability
Definition:
(n.) The state or quality of being irritable; quick excitability; petulance; fretfulness; as, irritability of temper.
(n.) A natural susceptibility, characteristic of all living organisms, tissues, and cells, to the influence of certain stimuli, response being manifested in a variety of ways, -- as that quality in plants by which they exhibit motion under suitable stimulation; esp., the property which living muscle processes, of responding either to a direct stimulus of its substance, or to the stimulating influence of its nerve fibers, the response being indicated by a change of form, or contraction; contractility.
(n.) A condition of morbid excitability of an organ or part of the body; undue susceptibility to the influence of stimuli. See Irritation, n., 3.
