A small flu can lead you to your own immune system making a vital mistake for killing healthy neurons which ends up destroying your body. It happens very rarely and is not likely to happen but can happen any second. This disease weakens your body till you are very venerably which may lead you to death.

What Does The Disease Do?

Multiple sclerosis damages and destroys brain tissue, the tissue on the back of your spine, and neurons. Everything gets damaged by demylenation, which makes multiple sclerosis an autoimmune disease. An autoimmune disease occurs when your own immune system attacks healthy cells and tissue that are not doing anything bad to your body. This makes everything in your body weakened and destroyed. Your senses, your balance, your ability to move your arms and legs and so on will be affected. Multiple sclerosis is a disease of which we don’t know what produces the attacks or flare ups, but we do know what happens inside your body if you have it. Multiple sclerosis is a degenerative disease. This means it gets worse and worse every day.

Affecting The System

MS causes demylenation. Demylenation is when the myelin sheath gets damaged which does not allow messages to pass smoothly through the axon. The myelin sheath is the fatty cover that protects the cell. Demylenation happens when the immune system sends white blood cells to protect the body from viruses that barged in. The immune system makes a vital mistake be detecting normal cells as intruders and so the immune system starts to attack and kill the intruders they have detected which ends up weakening the body. Brain tissue also gets damaged by demylenation but brain tissue does not get damaged from the myelin sheath since brain tissue is not a cell. Multiple sclerosis can damage your entire body because it eliminates everything in the nervous system and the nervous system controls everything in your body.

Causes

There are certain diseases that no one knows for sure how you get them .MS is one of them. MS is a very mysterious disease that can affect you at any moment but you won’t feel anything at first. Neurologists are still trying to find out what causes the disease to prevent it from happening. You usually get MS between ages 20-40 but it can occur at any age. Multiple sclerosis is luckily not a contagious disease so if you live with someone who has the disease you can’t get it from him or her, no matter what you do. Mostly women get diagnosed with multiple sclerosis.

How Are We Going To Treat It?

There is no absolute cure for multiple sclerosis, but there are loads of treatments you can take if you have it. A drug was discovered in 1993.Now its more advanced and reduces the amount of demylenation happening. It even starts to close the patches in the myelin sheath. There are different treatments you can take because the treatment depends upon where the attack of MS takes place in your body

It is tough to live with multiple sclerosis because it would weaken your body harshly until you no longer can move your legs or arms and other horrible things. Not everybody dies when they are diagnosed with this horrible disease even though it takes over your body at some point. Luckily these days we have advanced medicine we have treatment that weakens the effect of multiple sclerosis.

Ramlieh was a fun trip I honestly think it was great that the school had organized the field trip. The fun nest part of the trip was going on the obstacles above us. It was scary in some parts like walking on the logs, and balancing on one rope but with rope strapped around us it didn’t feel that it was that risky. I also liked the 2 hikes that we took and when we rubbed so much face paint that came of some random rocks that the teachers found while we were going uphill in the middle of the hike. We started rubbing our faces with so much of the colors that came of the rocks and when we were going back I noticed that the mountains looked liked a perfect picture. After we came back and ate and changed and played cards in the lobby we were all ready for the night hike which was very nice looking at the stars and not seeing who was who and what was what and then I put the stars into different shapes in my head while we stopped to look at them. It was a fun trip and I am looking forward to going there again.

Sand Dunes: Huge piles of Sand

Sand dunes are huge hills made of sand that can weigh up to tons. They come in several shapes and sizes like crescents or star shaped and many other forms. Some make loud booming sounds when they are disturbed! Scientists are still trying to find out why. So what shapes these piles of sand?

Sand Dune Formation

Sand dunes are formed when wind lifts up a huge quantity of sand and deposits it on a certain obstacle such as a rock. Later on, when the sand piles up in a huge quantity, it forms a barrier. When the barrier gets really big after a long period of time, it loses balance which makes it easy for the wind to break the sand barrier. Then the wind gives it shape and there you have it, a sand dune is formed. Sand dunes can be formed by two agents of weathering; wind and waves. The same process takes place when waves create sand dunes and when wind creates sand dunes. Creating sand dunes takes weathering, erosion, and deposition. Weathering is when rock breaks up into smaller pieces which turn into sediments over a period of time, and if there were no sediments there would be no sand because sediments are sand. Erosion is the movement of sediments while deposition is the end of erosion. Sand needs weathering because as I told you before, weathering creates sand. Dunes also need erosion because in order to have a sand dune, a huge amount of sand should be dumped in one spot, but if there was no erosion the sand would not be able to move at all. Last but not least dunes need deposition in order to get the sand to stop in one spot.

Where Are Sand Dunes Located?

You find sand dunes on the European coast that is bordering the Atlantic Ocean. You also find sand dunes on the western side of North America and of course all around sandy desserts. You find them on the European coast because waves create sand dunes, and the Atlantic Ocean has humongous waves. You find sand dunes on the western side of North America because California is a very windy place and is next to the Pacific Ocean. Another reason for sand dunes to be found on the western side of North America because you can find some desserts there You find sand dunes in every sandy desert, because deserts are often windy and sandy which makes the end product of sand and wind together Easy to predict.

The Most Famous Sand Dune

The most famous sand dune is the Cerro Blanco Sand Dunes in Peru. It is the highest sand dune in the world. The real name of this sand dune is in Quechua language is Yuraq Orqjo which means White Mountain. It is located on the east of Nazca Valley. The height of the Cerro Blanca Sand Dune is 2070 m.

In my opinion, I think sand dunes will be eroded in the sea in the future. I think this because if erosion keeps going on for years eventually something has to go wrong. And if there was a lot of eroded sand in the sea either the sea level will get higher or the sea turns into a gigantic pile of mud! And there you have it. I hope you one day get the chance to go see one of those huge gigantic sand dunes.

We were assigned to write a number line and it had to be challenging for our teacher to solve. It was for fun since we had to solve the number lines our teacher gave us almost every day. It was fun because we were the ones making the number lines for her to solve, not struggling to solve them.
