aphs of the living model. The motor points decrease in irritability as we get further away fromthe main nerve centers. The motor points are also influenced by the physique of the person,and are not as marked in the large or fat, as in the small and lean. Themuscular development also makes a difference, the larger and coarser thetissues the more current is required. The state of the health of the subject also makes a difference in theconductivity, and therefore in the muscular excitability. A strong fullblooded person will be a better subject than a weak, anaemic, debilitatedperson. It has been shown that different nerves will vary in their normal elec-tric excitability, and the following list of ten prominent nerves shows theirrelative order of excitability: 1, Spinal accessory; 2, Branch to levator angulae scapulae; 3, Ulnar; 4,Median; 5, Facial; 6, Cervical plexus; 7, Anterior crural; 8, Externalpopliteal; 9, Musculo-spiral; 10, Internal popliteal. 208 THE KI.KCTRO-THKRAPBUTIC GUIDE
