Effects of Alcohol on the Brain

It is important to have information when it comes to how the brain works to know the various effects of alcohol on the brain.
The brain is responsible for the control of every system of the body including the digestive, respiratory and the muscular.
So, how does the brain manage to do all this.
The brain does its work by using sequences of chemical, physical and electrical motions between cells.
Chemical signals are used among cells while electrical signals are used within cells.
These are called neurotransmitters.
A synapse is an area in between cells wherein active neurotransmitters are located.
Expelled neurotransmitters go through synapses and bond to receptors(receiving cell membrane specific to neurotransmitters).
Such actions result in chemical, physical or electrical changes on the receiving cells.
These excite the said cells in carrying out actions or prevent them from doing one.
The effects of alcohol on the brain includes the impediment of normal neurotransmission when alcohol reaches synapses.
Effects of alcohol on parts of the brain Alcohol affects different parts of the brain in different ways.
Alcohol and the cerebral cortex - the cerebral cortex is in charge of info processes from your senses, thought processes, most movement initiation of voluntary muscles and somewhat controls lower-order facilities of the brain.
The effects of alcohol on the cerebral cortex are as follows: - The potential for skewed judgment and thought processing - Decreased inhibition that may result in getting talkative as well as getting more confident - Dulled senses and an increased pain threshold The effects of alcohol on the brain can be more visible as the content of alcohol in the body increases.
Alcohol and the limbic system - the effects also includes its effects on the limbic system.
The limbic system has the hippocampus and the brain septal zone.
This controls the emotions as well as the memory.
Loss of memory and increased levels of emotion could be experienced as an alcohol induced effect.
Alcohol and the cerebellum - the cerebellum is the part of the brain that controls movement.
The effect of alcohol on this part of the brain results in muscle movements that are clumsy.
Alcohol and the hypothalamus and the pituitary glands - alcohol affects these parts of the brain as well.
The hypothalamus is influential on many mental functions aside from having control over them.
Likewise, it directs hormone release through the pituitary gland.
The hypothalamic nerve facilities are what controls getting sexually aroused aside from sexual performance and because of alcohol, sexual performance is low.
When under the influence of alcohol, a desire for sex increases while sexual performance decreases.
Alcohol also affects the process of urinating by delaying the pituitary gland in secreting the anti-diuretic hormone or ADH.
Kidneys will then produce more urine since ADH is delayed.
This hormone is key in the reabsorption of water by the kidneys.
