what do depressants do to the central nervous system？
Prescription CNS depressants act on the brain by increasing activity of GABA, a chemical that slows brain activity. People who start taking prescription CNS depressants usually feel sleepy and uncoordinated at first. They can also have poor concentration, confusion, lowered blood pressure, and slowed breathing.2018年3月6日
Regarding this,Do depressants suppress the central nervous system?
A type of drug that slows down brain activity, which causes the muscles to relax and calms and soothes a person. Central nervous system depressants are used to treat insomnia (trouble sleeping), anxiety, panic attacks, and seizures.
Accordingly,How do depressants affect the nervous system quizlet?
Depressants are drugs that tend to slow the central nervous system and slow brain activity by affecting the neurons. These drugs are dangerous because they slow heart and breathing rates and lower blood pressure.
One may also ask,Do depressants speed up the central nervous system?
Essentially, depressants slow down the body parts controlled by the central nervous system, while stimulants speed up the central nervous system's activity, including the brain.
Furthermore,How do depressants affect the nervous system and behavior?
Central nervous system depressants work by increasing the production of the neurotransmitter GABA, which in turn slows down brain activity and produces feelings of relaxation, drowsiness, and a number of other effects, including: Lowered blood pressure. Dilated pupils. Confusion or disorientation.
Definition of Depressants. Depressants are substances that can slow brain activity. They are used to reduce reactions in the body and relax muscles. They slow down the function of the nervous system by enhancing an effect of a type of neurotransmitter called GABA.
Effects of Drugs on The Brain & Neurotransmitters Mind-altering drugs may slow down or speed up the central nervous system and autonomic functions necessary for living, such as blood pressure, respiration, heart rate, and body temperature.
The danger is when the CNS is slowed too much, which can lead to unconsciousness, coma, and death. Mixing alcohol with other CNS depressants magnifies their impact and in many instances can be fatal.
