The synapse is the small gap separating two neurons, the presynaptic neuron (neuron that carries the impulse to the synapse,) and postsynaptic neuron (neuron that carries the impulse away from the synapse.) It separates the axon terminals of the presynaptic neuron from the postsynaptic neuron. The synapse is made of three major parts: a presynaptic neuron, a postsynaptic neuron, and a synaptic cleft. The presynaptic neuron contains the neurotransmitters, mitochondria, endoplasmic reticulum, and other cell organelles. The postsynaptic neuron contains receptor sites for the neurotransmitters in the presynaptic neuron. The synaptic cleft is the space between the presynaptic and postsynaptic neuron.…
At a synapse, a neuron releases a chemical known as a neurotransmitter that excites or inhibits another cell (Kalat, 2004). Synapses can occur in one of three places: on dendrites, on the soma, and on other axons. It 's a form of communication between neurons. The messages are carried by neurotransmitters and then released be terminal buttons. Synapses are very critical for almost all aspects of…
The darker effects on the mind include hostile behavior due to serotonin levels dropping which can disrupt normal bran function. Glucose metabolism is also lower in alcoholics and since sugar is brain food this also leads to a disruption in normal brain function. Alcoholics also experience lowered levels of thymine which leads to brain damage and even diseases such as Korsakoff disease. Alcohol abuse can result in the loss of neurons in…
Alcohol has the ability to depress the central nervous system, it slows down the brain, and delivers a…
Much of the brain is made up of highly specialized neurons. They interact to control the five senses, thought, mood and motion. Within the nervous system a process to which the neurons in the body communicate is called Chemical synapses which is a specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands seeing as the flow of information around the brainis achieved by electrical activity. Chemical synapses allow neurons to form circuits within the central nervous system. They play a crucial role to the biological computations that underlie perception and thought as neurons communicate in structures called synapses where neurons send and receive information. The sending neuron is known as the pre-synaptic neuron (which is before the synapse )and the receiving neuron is known as the post-synaptic(after the synapse) which is in the synapse transmission process. So in other words the synapse consist of two neurons, one of which is sending information to the other. They allow the nervous system to connect to and control other systems of the body. At a chemical synapse, one neuron releases a neurotransmitter into a small space (the synapse) that is adjacent to another neuron.…
Alcohol can affect your body in many ways such as your liver and many other major body organs. “But long term, heavy alcohol abuse has more lasting effects on the brain. Research studies show that between fifty and seventy-five percent of alcoholics experience difficulties in learning, remembering, perceiving, and solving problems” (Berger 2).…
Alcohol is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine into the bloodstream. Alcohol affects every organ in the body. Individual reactions to alcohol vary and are influenced by many factors such as age, gender, physical condition, how quickly the alcohol was consumed, etc. Alcohol starts to affect the brain…

When alcohol is consumed the brain is unable to send the correct messages through the body and disrupts communication between the nerve cells . It suppresses nerve activity, throughout the cerebral cortex and the central nervous system (CNS) by significantly slowing down the pace of actions taken and information received . Consumption also alters two of the major neurotransmitters within the brain being the Hippocampus and the Prefrontal Lobe . The hippocampus is responsible for memories, and occasionally after one or two standard drinks (SD)people are prone to forgetting recently learned things. Being that it is a sensitive part of the brain (see figure.1), alcohol is poisonous…
How does alcohol actually affect our brain? Well alcohol has something in common with most other drugs and this is that it affects our brain and we like it. Unfortunately our system becomes tolerant to small quantities of alcohol, so we start drinking larger quantities to maintain the same effect. The consequence being that we drink more and more to feel the same and there's nothing that is going to stop us from becoming an alcoholic.…
Five basic effects of alcohol on the central nervous system include, acute and chronic brain damage, peripheral nerve dysfunction, cerebral and cortical atrophy…
The effects of alcohol have an effect on the brain vary as the amount of alcohol is consumed into the blood stream. The first part of the brain to be effected by the consumption of alcohol is Cerebral Cortex. This is the region of the brain that process the though process and consciousness. The effect of this region is that it suppress the inhibition-processing center, it affects the eyes, ears, and mouth senses.…
Alcohol is both an antagonist and agonist. As an antagonist alcohol reduces some effects of the neurotransmitters while as an agonist it increases the effect of some neurotransmitters (Berman, & Marinkovic, 2003). As an antagonist alcohol reduces the effects of glutamate which results to effects such as slur in speech, loss of memory and slackness in walking. Agonist effects are seen in instances where alcohol acts as painkillers, increased feeling of relaxation and generally feeling drowsy.…
Alcohol is the oldest and most widely used drug in the world. Young adults that drink before the age 21 are more likely to end up damaging their body. At a young age kids can end up getting alcoholism, which is a serious drinking problem. During young adulthood anyone can become an alcoholic by starting at such a young age. Meanwhile, Alcohol can raise many emotions and mood to a person’s body. In addition, the mind of a person is growing from the age 15-24. So alcohol has a toxic effect on the brain of a minor. Secondly, the increased dose of drinking alcohol may cause death because their bodies are so small the brains can not handle it. According to Laura Dean Mooney, most college students drink to have fun with their roommates and friends.…
Most people who are partying through the night at bars and nightclub aren't wondering how alcohol affects their nervous system. The main goal is to get drunk and have a good time. Yet alcohol inhibits the brain's ability to send signals to the spinal cord and nerve endings. The nervous system slows down greatly because it is absorbed right into the blood stream. Alcohol works the same as a sedative without the benefit of going through your digestive system. Because it enters directly into your blood stream, it is very dangerous.…
