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.
They transmit signals across a chemical synapse, such as in a neuromuscular junction, from one neuron (nerve cell) to another target neuron, muscle cell, or gland cell. Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by receptors on other synapses.ere are a few examples of important neurotransmitter actions: 1  Glutamate is used at the great majority of fast excitatory synapses in the brain and spinal cord. 2  It is also used at most synapses that are modifiable, i.e. capable of increasing or decreasing in strength.
