1.   Rather, the axons of the sensory neurons carry impulses back into the spinal cord.

2.   Not all transmitters excite the post synaptic membrane, some inhibit it so that it is more difficult for it to carry an impulse.

3.   A person with OCD does not have enough serotonin to carry the impulse over that synapse.

4.   Chemical messengers carry the impulse across the synapse.

5.   The principle was identical to the tape recorder, still a few years off, except that the machines used thin metal wire to carry magnetic impulses.

6.   The result is pain, numbness, tingling and weakness in the part of the body to which the nerve normally carries impulses.

7.   The leads are wires and sensors that carry electrical impulses to the heart to stimulate it.

8.   The surgery is aimed at relieving pressure on the nerve that carries sight impulses to the brain.
