NEURON ACTION POTENTIAL samer kareem 4,121 Views • 3 years ago

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Parkinson's Disease Drugs
Parkinson's Disease Drugs samer kareem 1,935 Views • 3 years ago

There have been rapid and remarkable changes over the recent past in treating Parkinson's disease. The development of new drugs and an understanding of how best to use them and the older drugs have significantly improved the quality of life of people with the disease. There are two general approaches to the treatment of Parkinson's disease with medication. The first approach attempts to increase the levels of dopamine in the brain and the second approach attempts to improve the symptoms of Parkinson's disease by other means. Most patients with Parkinson's disease can initially be treated with drugs that adequately alleviate their symptoms. If or when medications are not sufficiently effective, new, highly effective and safe surgical treatments are also available.

Diuretics, sometimes called water pills, help rid your body of salt (sodium) and water. Most work by making your kidneys release more sodium into your urine. The sodium then takes water with it from your blood. That decreases the amount of fluid flowing through your blood vessels, which reduces pressure on your vessel walls.

ALPHA & BETA BLOCKERS
ALPHA & BETA BLOCKERS samer kareem 4,136 Views • 3 years ago

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.

Dementia Signs and Symptoms
Dementia Signs and Symptoms samer kareem 1,283 Views • 3 years ago

Dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities. Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.
