Use of illicit* drugs or misuse of prescription drugs can make driving a car unsafeâjust like driving after drinking alcohol. Drugged driving puts the driver, passengers, and others who share the road at risk. Photo by Â©iStock.com/Joshua Sowin.
NEUROTRANSMITTERS are the brain chemicals that communicate information throughout our brain and body. They relay signals between nerve cells, called âneurons.â The brain uses neurotransmitters to tell your heart to beat, your lungs to breathe, and your stomach to digest.
The neuron (nerve cell) is the fundamental unit of the nervous system. The basic purpose of a neuron is to receive incoming information and, based upon that information, send a signal to other neurons, muscles, or glands.Neurons are designed to rapidly send signals across physiologically long distances.They do this using electrical signals called nerve impulses or action potentials.When a nerve impulse reaches the end of a neuron, it triggers the release of a chemical, or neurotransmitter. The neurotransmitter travels rapidly across the short gap between cells (the synapse) and acts to signal the adjacent cell.hey do this using electrical signals called nerve impulses or action potentials.
