WebMar 26, 2016 · The signal must traverse the synapse to continue on its path through the nervous system. Electrical conduction carries an impulse across synapses in the brain, but in other parts of the body, impulses are carried across synapses as the following chemical changes occur: Calcium gates open. WebThe nerve carrying the impulse crosses to the opposite side at the base of the brain. The impulse is sent down the spinal cord. The impulse crosses a synapse between the nerve fibers in the spinal cord and a motor nerve, which is located in the spinal cord. The impulse travels out of the spinal cord along the length of the motor nerve. great southern homes devonshire
