A flexor withdrawal reflex shows all the following properties, except :-a- recruitmentb- prepotent c- non-fatigable d- irradiation
A student tested their patellar tendon (knee-jerk) reflex normally and with the JENDRASSIK MANEUVER (clasping
their hands together and attempting to pull them apart). While performing the Jendrassik maneuver, their reflex
response was TWICE AS HIGH when compared to the control condition. Explain.
