Abstract
The electromyographic response of the striated urethral sphincter has been evoked following stimulation of its motor nerve, the pudic nerve. Stimulation of the intact nerve fires the muscular fibres directly with a latency of approximately 1.2 msec and also in a reflex manner via the ipsilateral and contralateral pathways. The two paths transmit the reflex responses with a minimal latency of 8–10 msec (chloralose). During Halothane anaesthesia the reflex appears with a longer latency (up to 26 msec). The variability of this latency and the central delay of around 5 msec agree well with a polysynaptic central pathway.Keywords
