Vedclass · Answer

(B) Chronaxie is a physiological term used in neurophysiology to describe the excitability of a tissue (like nerve or muscle).It is defined as the minimum time required to excite a tissue using a current that is twice the strength of the rheobase.Rheobase is the minimum current intensity required to produce an action potential when the duration of the stimulus is infinite.Therefore,chronaxie provides a measure of the excitability of the tissue; a shorter chronaxie indicates higher excitability.
