How Nerve Cells Communicate?
Nerve cells communicate with each other by way of electrical signals or impulses, traveling at up to 400 km (250 miles) per hour, allowing information to be processed, assessed and acted upon within milliseconds.
A single nerve cell may connect with hundreds of others, and the junction between these cells is known as a synapse.
The synapse is, in reality, a gap between the nerve cells, and the electrical impulse travels across the gap by way of specific chemical messengers known as neurotransmitters.
The nerve cells of the body branch out to supply every muscle and particle of skin, as well as all of the internal organs such as the heart, intestines and lungs.
Many of these nerves are bundled together like rope, carrying messages from the periphery, through the spinal cord to the brain. Similar messages travel back from the brain to the nerve fibers in the muscles to initiate movement, for example.
