The radial and ulnar nerves were examined electrophysiologically in 30 normal mongrel dogs, 11 males and 19 females, aged between two and six years. The proximal and distal evoked muscle potentials of motor stimulation of the radial nerve had an average latency of 2.46+0.72ms and 1.58+0.62ms, an average amplitude of 8.79+2.26mV and 9.52+2.42mV, and an average duration of 2.85+0.76ms and 2.71+0.75ms, respectively. The proximal and distal evoked muscle potentials of motor stimulation of the ulnar nerve had an average latency of 4.17+0.53ms and 2.67+0.38ms, an average amplitude of 10.72+2.60mV and 11.72+2.81mV, and an average duration of 2.23+0.38ms and 2.04+0.35ms, respectively. The average motor conduction velocity was 66.18+7.26m/s for the radial nerve and 60.50+7.86m/s for the ulnar nerve.
