[Illustration: Fig. 22.
Scheme of the decrement of the excitation wave in the narcotized
stretch of a nerve. A--The narcotized stretch (indicated by the cross
section of the chamber) is 30 mm. long. The ordinates of the dotted
lines indicate the amount of the decrement. If the decrement is slight
(upper dotted line), the excitation wave passes the narcotized stretch
and increases again on entering the normal stretch. If the decrement is
great (lower dotted line), the excitation wave is obliterated towards
the end of the narcotized stretch and the muscle remains at rest.
B--The narcotized stretch is 15 mm. long. The decrement is slight.
The excitation wave can therefore pass into the normal stretch and
here increase again. C--The narcotized stretch is 15 mm. long. The
decrement is great. The excitation wave is obliterated, therefore, in
the narcotized stretch, and the muscle remains at rest. ]
