    • ‘A conventional epidural will numb or block both the sensory and motor nerves as they exit from the spinal cord, giving very effective pain relief for labor but making the recipient unable to move the lower part of her body.’
    • ‘Calcium is released from internal stores when motor nerves instruct the muscle to contract.’
    • ‘When motor nerves are affected, muscles become weak.’
    • ‘Choline is important for the movement of fat into cells and is an important component of the neurotransmitter acetylcholine, which is released from motor nerves to stimulate muscles to contract.’
    • ‘It also acts on the nervous system to immediately increase strength by enhancing the firing of the motor nerves that supply muscle fibers.’
    • ‘As an anatomist, Eristratos was the first to distinguish between the sensory and motor nerves.’
    • ‘The advantage is that long-lasting anesthetic agents can be delivered outside of the spinal column to the sympathetic ganglia, thereby avoiding any blockade of sensory or motor nerves.’
    • ‘Thus, each surviving motor nerve must now stimulate a greater number of muscle fibers.’
    • ‘A year later he began vascularised nerve grafting: in two patients with substantial missing sections of the radial motor nerve he transplanted sections of sensory nerve, producing considerable functional recovery.’
    • ‘This hormone also increases muscle strength by causing the nervous system to intensify the firing of the motor nerves that supply muscle fibers.’
    • ‘The toxin attacks the endings of motor nerves to paralyze muscles.’
