There are to be mentioned of the nerve points, thecrural nerve, at the end of the inner third of Poupartsligament, which lies very deep and is, therefore, oftennot excitable (or only with difficulty by considerablepressure of the electrode upward, outward, and back-ward).

(See Plates 21-24.) Nerves and Mus-cles of the LowerExtremity Crural Nerve In the lower extremity the search for the most excit-able points is more difficult than in the upper, since fre-quently a much thicker layer (composed of skin, con-nective tissue, and in particular fat) is found betweenthe electrode and the nerve or muscle, so that, withthe inclination of the electric current to arc formation, agreat part of the current is lost in the good conductinginterposed tissue before a fraction reaches the muscleor the nerve. Therefore we frequently need, especiallyin the thigh, large current strengths to produce a visi-ble effect. Several very deep-lying points can not bereached at all in many individuals.
