title: Physiological identification of static beta axons in primate muscle.
abstract: Skeletofusimotor (beta) axons exerting a static action on spindle primary endings were identified in the peroneus brevis and tertius muscles of the cynomolgus monkey. In most of the identified static beta motor units, the extrafusal portion was of the fast-contracting fatiguable type.
