Mind over matter the brain’s response to methamphetamine nida for teens gas pressure definition chemistry


No matter how Methamphetamine is used, it eventually ends up in the bloodstream where it is circulated throughout the brain. Methamphetamine can affect lots of brain structures, but the ones it affects the most are the ones that contain a chemical called dopamine gas stoichiometry practice. The reason for this is that the shape, size, and chemical structure of Methamphetamine and dopamine are electricity and magnetism physics similar. Before I tell you more about dopamine and Methamphetamine, I’d better tell you how nerve cells work.

Your brain is made up of billions of nerve cells (or neurons). Neurons come in all shapes and sizes, but most have three important parts: a cell body that contains the nucleus and directs the activities of the neuron; dendrites, short fibers that receive messages from other neurons and relay them to the cell body; and an axon, a long single fiber that carries messages from the cell body to dendrites of other neurons.

Axons of one gas x strips after gastric sleeve neuron and the dendrites of a neighboring neuron are located very close to each other, but they don’t actually touch. Therefore, to communicate with each other they use chemical messengers known as neurotransmitters. When one neuron wants to send a message to another neuron it releases a neurotransmitter from its axon into the small space that separates the two neurons. This electricity wiki space is called a synapse. The neurotransmitter crosses the synapse and attaches to specific places on the dendrites of the neighboring neuron called receptors. Once the neurotransmitter has relayed its message, it is either destroyed or taken back up into the electricity and circuits ppt first neuron where it is recycled for use again.

There are many different neurotransmitters, but the one that is most affected by Methamphetamine is dopamine. Dopamine is sometimes called the pleasure neurotransmitter because it helps you feel good from things electricity cost per kwh by country like playing soccer, eating a big piece of chocolate cake, or riding a roller coaster. When something pleasurable happens, certain axons release lots of dopamine. The dopamine attaches to receptors on dendrites of neighboring neurons and passes on the pleasure electricity billy elliot broadway message. This process is stopped when dopamine is released from the receptors and pumped back into the neuron that released it where it is stored for later use.

Scientists are using brain imaging techniques, like positron emission tomography (called PET for short), to study the brains of human Methamphetamine users. They have discovered that even three years after long-time wd gaster theme Methamphetamine users had quit using the drug, their dopamine neurons were still damaged. Scientists don’t know yet whether this damage is permanent, but this research shows that changes in the brain from Methamphetamine use can last a long time. Research with animals has shown that the drug Methamphetamine can also damage neurons that contain serotonin. This damage also h gas l gas unterschied continues long after the drug use is stopped.

These changes in dopamine and serotonin neurons may explain some of the effects of Methamphetamine. If a person uses Methamphetamine for a long time, they may become paranoid. They may also electricity projects for 4th graders hear and see things that aren’t there. These are called hallucinations. Because Methamphetamine causes big increases in blood pressure, someone using it for a long time may also have permanent damage to blood vessels in the brain. This can lead to strokes caused by bleeding in the brain.
