What is a stroke????


A stroke is a condition in which the brain cells suddenly die because of a lack of oxygen. This can be caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain. The patient may suddenly lose the ability to speak, there may be memory problems, or one side of the body can become paralyzed.

The two main types of stroke include ischemic stroke and hemorrhagic stroke.


  • Ischemic stroke accounts for about three-quarters of all strokes and occurs when a blood clot, or thrombus, forms that blocks blood flow to part of the brain. If a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus. This wandering clot may be carried through the bloodstream to the brain where it can cause ischemic stroke.
  • A hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and fills the space between the brain and skull with blood (subarachnoid hemorrhage) or when a defective artery in the brain bursts and fills the surrounding tissue with blood (cerebral hemorrhage).
Both types of stroke result in a lack of blood flow to the brain and a buildup of blood that puts too much pressure on the brain.

The outcome after a stroke depends on where the stroke occurs and how much of the brain is affected. Smaller strokes may result in minor problems, such as weakness in an arm or leg. Larger strokes may lead to paralysis or death. Many stroke patients are left with weakness on one side of the body, difficulty speaking, incontinence, and bladder problems.

Here are some facts that i found about who gets  a stroke, its interesting that just based on your culture group you may be at risk of having a stroke. It doenst necessarily maen that you will get a stroke just because you smoke or because you are hispanic, no it just means theres a higher chance because thats what statistcs show and because its more common amongst people who have any of these things.

Anyone can suffer from stroke. Although many risk factors for stroke are out of our control, several can be kept in line through proper nutrition and medical care. Risk factors for stroke include the following:

  • Over age 55
  • Male
  • African American, Hispanic or Asian/Pacific Islander
  • A family history of stroke
  • High blood pressure
  • High cholesterol
  • Smoking cigarettes
  • Diabetes
  • Obesity and overweight
  • Cardiovascular disease
  • A previous stroke or transient ischemic attack (TIA)
  • High levels of homocysteine (an amino acid in blood)
  • Birth control use or other hormone therapy
  • Cocaine use
  • Heavy use of alcohol - researchers from the University of Lille Nord de France, Lille, France, reported in the journal Neurology that heavy regular drinkers have a considerably higher risk of stroke early in life compared to others.
  • Men from divorced families have a higher chance of suffering a stroke than those from families which are still intact

ADDICTION!!!

People with an addiction do not have control over what they are doing, taking or using. Their addiction may reach a point at which it is harmful. Addictions do not only include physical things we consume, such as drugs or alcohol, but may include virtually anything, such abstract things as gambling to seemingly harmless products, such as chocolate - in other words, addiction may refer to a substance dependence (e.g. drug addiction) or behavioral addiction (e.g. gambling addiction).
Addiction to drugs, food, shopping, social networks, etc..etc. People everyday are experiencing a type of addiction; however regardless of what the addiction may be, the seriousness to this is that an addiction to something exists.
The most typical addiction problem that we see out there is the addiction to drugs. Yes, drug addiction constitutes the most common addiction in the world. The worst part of it is that people die everyday from this and children not only adults take part of this.
Addiction to food is another harmful thing because this is slowly killing people. We are facing the problem of obesity and nowadays people take their health for granted and indulge in all the fast food eating that it can eventually become a habit that at one point you don't see the addiction that you are facing.
Who doesn't love to shop, play video games or like to check their Facebook or Twitter? I cant lie and say that i don't enjoy this things, because i do, however i don't consider myself addicted to any of these things.
So next time have a reality check and see if you consider yourself addicted to any of these things.

What a system!!!


The nervous system is the pathways that the brain uses to send information through out the body. The nervous system is needed to relay messages to the brain and back to different parts in the body. If the nervous system becomes disabled in any way, a person would lose a lot of its normal bodily functions.
The major organs of the nervous system are the spinal cord and the brain. They are the transmitters and both are needed in healthy condition to operate our nervous system efficiently.
The nervous system is composed of two parts: 

The central nervous system consisting of the brain and spinal cord.
The peripheral nervous system consisting of all the neurons in the body, other than those in the brain and spinal cord.
It is a vital component of the human body, which helps in sensing and movement. The smooth functioning of the five senses - touch, sight, taste, hearing and smell, is attributed to it.

There are some fats about the nercvous system that we didnt know about like:
  • The brain weighs approximately 3lbs
  • A man's spinal cord is a bundle of nerve tissue that is about 17.7 inches long, an average woman's spinal chord is 16.9 inches long
  • In humans, the right side of the brain controls the left side of the body, while the left side of the brain controls the right side of he body
  • At a given point of time, only four percent of the cells in the brain are active, the rest are kept in reserve.
  • In a child developing inside the womb, neurons grow at the rate of 250,000 neurons per minute.
  • By the time of its birth, the baby's brains consists of around 10 million nerve cells.
  • The weight of the brain in average adult males is 1375 grams, while in females it is 1275 grams and as we grow older the brain loses a gram each year
  • At a given point of time, only four percent of the cells in the brain are active, the rest are kept in reserve. 
Its interesting how much we don't know about how our nervous system works and the interesting facts but here's some facts and some background information to educate us more about this topic.

1.3 The Use of Animals in Research





Animal research has been a controversial topic for so long already that it’s difficult to support either side of the controversy, as they both have well thought of points that help to reason their claims
On one side, we have abolitionists who are against animal research as they believe that animals should have rights just like we do. They have a perspective whereby animals are no longer regarded as things to be owned and used.  On the other side, we have the scientists who are doing all these tests and research to improve our lives. They aren’t harming animals for fun or just because they want to, no they are doing this to help human beings by finding cures or improving our daily supplies like beauty products or medication. Yeah, they are harming innocent creatures that can’t talk or do something to make them stop, but they are the closest things we have to test on besides humans.
I have to say that I support this idea to some degrees because I do believe in gaining knowledge to figure things out for treatments and for other things but at the same time it’s not right to treat animals with  such cruelty when they do not deserve it. Yes we are fighting to survive and we are harming others in the process, but that's the only way that we can help others, it’s just how we are improving in life. 
Like I said, this topic has it pros and cons but at the end it’s something that has been going on for many years and it will still probably go on for many more...We really won’t ever be able to stop this, but we however can slow things down by figuring other ways in which we can gain the information and knowledge that we are obtaining from doing this experiments. We are evolving and just like technology is taking over many things, we may as well figure out how to use this in our advantage and stop animal cruelty once and for all.
