[ Latin] The state of excitation provoked by stimulation; especially, a state of over-excitation due to the excessive reaction of a part to stimuli, and not associated with structural changes. I. may be due to the over-application of stimuli to a part( Direct i.), to reflex influences originating in other parts( Reflex i, Sympathetic i. ), or to excess of functional activity( Functional i.), although the latter term is generally used to denote a condition like spinal i. in which without gross disease there is marked derangement of function, so that slight exertion produces marked symptoms. Heretic irritation, with the production of hectic fever; properly a form of septicaemia. Spinal irritation, see Spinal.
