What is alcohol?
Alcohol is a natural substance created by the fermentation of other natural things such as grains, fruits or vegetables. When humans consume alcohol it goes through the digestive pathway, 20% digested normally in the stomach and about 80% in the small intestine. Once digested the alcohol goes into the persons blood stream and from their into the central nervous system (the brain and spinal cord). The central nervous system controls all body functions so once impaired by alcohol a person does not function normally. Alcohol is considered a depressant drug and once inside the central nervous system it slows down all body functions, it alters a person's perceptions, emotions, movement, vision, and hearing. At this point of altering it is considered intoxication.
What is a neurotransmitter?
"Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers. And they and their close relatives are produced by some glands such as the pituitary and the adrenal glands. In this chapter, we will review some of the most significant neurotransmitters."
