It is important to have information regarding the operation of the brain to understand the different effects of alcohol on the brain. The brain is responsible for controlling all systems of the body, including the digestive, respiratory and muscular. So how the brain manages to do all this. The brain does its job using sequences of movements chemical, physical and electrical between cells. Chemical signals are used between cells, while the electrical signals are used in the cells. These are called neurotransmitters.
A synapse is an area in which neurotransmitters between the active cells are located. Expelled undergo synapsis and neurotransmitters binding to specific receptors (neurotransmitter receptors of the cell membrane). These actions result in chemical changes, physical or electrical in host cells. These excite these cells in shares of the scene or to prevent them from making a.
The effects of alcohol on the brain includes depreciation of normal neurotransmission when alcohol reaches synapses.
Effects of alcohol in the parts of the brain
Alcohol affects different parts of the brain in different ways.
Alcohol and the cerebral cortex - the cerebral cortex is responsible for information processing of their senses, thought processes, plus the initiation of voluntary muscle movement and somewhat lower brain control monitoring facilities. The effects of alcohol in the cerebral cortex are:
- The possibility of partial judgment and treatment of thought
- Inhibition which may result in obtaining talkative and confidence Decrease
- Sense and blunt pain threshold increase
The effects of alcohol on the brain may be more visible than the alcohol content in the body increases.
Alcohol and the limbic system - the effects also includes its effects on the limbic system. The limbic system is the hippocampus and septal area brain. It controls emotions and memory. Memory loss and increased levels of emotion can be experienced as an effect induced by alcohol.
Alcohol and the Cerebellum - The cerebellum is the part of the brain that controls movement. The effect of alcohol in this part of the brain that causes muscle movements are clumsy.
Alcohol and hypothalamus and pituitary gland - Alcohol affects those parts of the brain too. The hypothalamus is influential in many mental functions apart from having control over them. Additional tests, through the release of the hormone from the pituitary gland. facilities nerve hypothalamus controls are sexually excited, besides sexual and function due to alcohol, sexual performance is low. When you are under the influence of alcohol, increases sexual desire while sexual performance decreases.
The alcohol also affects the process of urination by delaying the secretion of the pituitary gland or antidiuretic hormone ADH. Then kidneys produce more urine ADH is delayed. This hormone is essential water reabsorption by the kidney.
