=
The nervous system is the higway along wich your brain sends and receives information about what is happening in the body and around it.This higway is made up of billions of nerve cells or neurons wich join together to make nerves.The two main parts of the nervous sytem are:=====

THE CENTRAL NERVOUS SYSTEM: The brain and the spinal cord make up the central nervous system.The brain lies protected inside the skull and from there controll

s all the body functions by sending and receiving messages trought nerves.



THE PERIPHERAL NERVOUS SYSTEM: The peripheral nervous system carries messages from and to the central nervous system.It sends information to the brain and carries out orders from the brain.Messages __#|travel__ trought the cranial nerves,those wich branch out from the brain and go to many places in the head such us the yea

rs,eyes or face.Messages can also trought to the spinal nerves wich branch out to the spinal cord.

The main parts of the nervous system are: The brain, the nerves, the neurons and the spinal cord.

The brain is the center of the nervous system.It is located in the head,usually close to primary sensory apparatus such as vision,hearing,balance, taste and smell .The brain of vertebrates is the most complex organ in its body.In a typical human the celebral cortex is estimated to contain 15-33 billion neurons.
 * The brain:**


 * The nerves:**

You have nerves all over your body wich have a a very important job.They __carry__ messages from your brain to all different parts of your body,that allow us to do different things.The whole network of nerves in your body is called the nervous system.**Your nervous system allows you to do many things.**

The human body is made up of trillions of cells.Cells of the nervous system,called **nerve cells or neurons**,are specializaded to __carry__ messages trouhgt an electrochemical process.The human brain has aproximately 100 neurons.Ich neuron transmits the information by an electric discharge.
 * The neurons:**

The spinal cord is long,thin,tubular bundle of nervous tissue and support cells that extends
 * The spinal cord:**

from the brain.The brain and the spinal cord together make up the central nervous system.The spinal cord is about 45cm in men and 43cm in women.

EXAMPLE: 1-__#|The eyes__ see something. 2-Then the eyes transmit the information to the brain. 3- Finally the information gets the brain and the brain reacts sending orders to the body. The nervous system is large and in charge.You couldn`t do any thing without your nervo

us system. The two main parts of the nervous system are the central nervous system and the peripherial nervous system.

__ The Goliath Bird eating Spider: __



= The **Goliath bird-eater Spider** is an arachnid belonging to the tarantula group, Theraphosidae. (by leg-span it is second to the giant hunts man spider), and it may be the largest by mass. The goliath bird -eater, The rephosaleblondi is a tarantula,and is the world's largest spider. Despite its name,the goliath bird -eating birds do not eat, but invertebrates such as crickets and meal worms , and small vertebrates such as mice and lizards .They kill their prey by injecting venom through their fangs. =

==

During low water season it lives in burows.When the rain comes,it migrates
into trees.The tarantula wait´s hidden in the trees and pounces on the prey coming up.

__ PARTS __

Their bodies are divided in two parts the cephalothorax and the abdomen.They have 4 legs on each side. = = = =

= = = = =__ What does it eat? __= Normaly: insects,rodents,lizards Rarely:birds,bats,snakes

Despite its name, the Goliath Birdeater does not normally eat birds. As with other species of spider, their diet consists primarily of insects and other invertebrates. However, because of its naturally large size, it is not uncommon for this species to kill and consume a variety of vertebrates. In the wild, larger species of tarantula have been seen feeding on rodents, lizards, bats and even deadly venomous snakes.

= __Venom and fangs__ =

Goliath birdeater is fairly harmless to humans, as are most species of tarantulas. Like all tarantulas, they have fangs large enough to break the skin of a human. They carry venom in their fangs and have been known to bite when threatened, but the venom is relatively harmless. They have tusks from 2 to 5 cm

= = The **Wright brothers**, **Orville** and **Wilbur** were two Americans credited with inventing and building the world's first successful airplane and making the first controlled, powered and sustained flight.

= = = __CHILDHOOD__ =

The Wright brothers were two of seven children born to Milton Wright of English and Dutch descent and Susan Catherine

Koerner of German-Swiss descent.Wilbur was born near Millville, Indiana, in 1867; Orville in Dayton, Ohio, in 1871. The brothers never married. In elementary school, Orville was given to mischie f and was once expelled. In 1878 their father brought home a toy "helicopter" for his two younger sons.An invention of Alphonse Pénaud. Made of paper, bamboo and cork with a rubber band to twirl its rotor, it was about a foot long. Wilbur and Orville played with it until it broke, and then built their own. In later years, they pointed to their experience with the toy as the initial spark of their interest in flying.

On Monday, December 14, 1903, when both the Wright flyer and the wind were ready, the brothers decided that Wilbur would take the first turn as pilot for the famous flight. They and the ground crew had carried the plane weighing six hundred pounds one quarter of a mile to a big hill, laid out the 60-foot monorail, and were ready to go. After an initial problem getting it unhooked becau se of the slope, the plane accelerated down the track so fast that Orville, running alongside to steady the wing by h

olding on to an upright, couldn't keep up. Wilbur turned the sensitive rudder up too sharply, the flying machine nosed up, slowed, came down in that position

, and the left wing hit the sandy hillside and swung the plane around, breaking several parts. Although they didn't consider this a real flight, they now knew it would work. Two days later, repairs had been completed, but the wind wasn't right. The following day, Thursday, December 17, 1903, would be the historic day. They realized it would be better t o lay the track on flat ground. The strong winds meant that Orville was riding the plane along the track, at a speed that allowed Wilbur to keep up easily, steadying the right wing as Orville had done 3 days earlier. Just after the Wright flyer lifted off the monorail, the famous picture was taken, possibly the most reproduced photograph ever, which Orville had set up .The flight wasn't much - 12 seconds, 120 feet. But it was the first controlled and sustained flight, one of the great moments of the century. The brothers flew 3 more times that day, covering more distance as they got used to the way the large front "rudder" responded in flight. Orville's second flight was 200 feet, and Wilbur's before it nearly as long. But the final flight of the day carried Wilbur 852 feet in 59 seconds. = =

The solar system The solar system consit of the sun, eight planets and their moons, comets and asteroids. They are all called celestial bodies. Everything in the solar system orbits the sun.





The sun **:**  The sun is the largest celestial body. It is much bigger than any planet .It is at the centre of the solar system. The sun is an enormous yellow star which provides the light and heat necessary for life on earth. The sun rotates on its owr invisible axis.



Mercuri

 It´s the first planet to the sun.  Temperatures on Mercury get up to 460 degrees Celsius.  It's a whopping 640 degree temperature change from the hottest to the coldest part of the planet.  Mercury has almost no **atmosphere**.  Mercury, like the Moon, is co vered with craters. Because the planet has no atmosphere, the asteroids never burn off

Venus The second planet away from the Sun. It has clouds of sulfuric acid in an atmosphere of carbon dioxide. Lava is found across the surface after being spewed from volcanoes.

The earth

The third planet from the Sun. The Earth is the only known planet where life can survive.We have a very narrow temperature range that allows water to remain a liquid. Most of our atmosphere is made of nitrogen (N), a relatively inert gas.

Mars

 Mars is the fourth planet from the Sun. It is a very active planet like the Earth. It even has polar ice caps like the Earth, with water in the north and solid carbon dioxide in the south.

Jupiter

 **Jupiter** is the largest planet in our Solar System.  Its mass is over 300 times the mass of the Earth. The Jovian planets are **gas giants** that orbit the Sun.  Its atmosphere have over 20 moons.

Saturn

 Saturn is the second largest planet in the Solar System.  It is amazing that a planet that has a diameter almost 10 times that of the Earth spins more than two time s as fast.  That speed also gives Saturn a bulge at its equator.

Uranus

 The seventh planet from the Sun is **Uranus**.  Uranus is a planet largely of gases.  It has a light blue color because of the **methane** in its atmosphere.  It is one of the four gas giants in our Solar System.

NEPTUNE  Neptune is huge in size  Neptune's atmosphereis made up of hydrogen and helium.  Neptune has large **storms** wirling in its atmosphere.

ASTEROID BELT  The asteroid belt is a 'belt' of rocky bodies between Mars and Jupiter that is centered around 2.7AU.  Most asteroids in the Main Belt are composed of three materials. 92.9% are composed of silicates (stone), 5.7% metals (mainly iron and nickel) and the rest as a mix of those materials and carbon-rich substances. The largest asteroid in the main asteroid belt is Ceres.

The moon When Galileo Galilei turned his telescope toward the moon in 1610 was able to distinguish two different surface regions. A dark regions called them "seas", which of course have no water and have names such as Sea of Serenity and Sea of Fertility, are plains with few craters. The rest of the lunar surface is brighter, and represents higher regions with a high density of craters, such as Tycho and Clavius. In the lunar surface there are mountain ranges that have names like Alps and Apennines, like on Earth The accident meteors An ancient meteorite reveals the solar system is 4.5682 billion years old, 1.9 million years older than we thought. The difference seems insignificant, but it could mean our solar system was actually born in the blast furnace of a supernova. In order to determine the age of the solar system, scientists look for meteorites that date back to the beginnings of the solar system. Some of these meteorites have tiny mineral deposits known as calcium-aluminu rich...

Has been changing the phone t o become a mobile phone = **1843 Now**= There are more types of phones

This is the first mobile found:media type="youtube" key="DMbGrakUHc4?feature=player_detailpage" height="360" width="640"



Its inventor was Martin Cooper in the 40s and his mobile phone was bigger than the mobile phones in the actuallity. With that phone you could only phone

The advances in mobile telephony can be traduced in successive generations from the early "0G" services like MTS and its successor Improved Mobile Telephone Service, to first generation (1G) analog cellular network, second generation (2G) digital cellular networks, third generation (3G) broadband data services to the current state of the art, and finally, th fourth generation (4G) native-IP networks.

Early services – 0G

MTS
This mobile service started in St. Louis in 1946 and introduced Mobile Telephone Service to one hundred towns and highway corridors by 1948. This service was a rarity with only 5,000 customers. Calls were set up manually by an operator and the user had to depress a button on the handset to talk and release the button to listen. This mobile phones used radio channels, only three customers in any given city could make mobile telephone calls at one time.

Mobile Telephone Service was expensive, costing US $15 per month, plus $0.40 per local call, equivalent to about $176 per month and $ 3.50 to $4.75 per call in 2012 dollars.

Analog cellular networks – 1G

The first analog cellular was commercially in America in 1978 by Ericcson, Israel in 1986, and Australia in 1987.

This mobile phone used radio channels too

Digital cellular networks – 2G

In the 1990s, the 'second generation' mobile phone systems emerged. Two systems competed for supremacy in the global market: the European developed GSM standard and the U.S. developed CDMA standard. These difference from the previous generation by using digital instead of analog transmission

In 1993, IBM Simon was introduced. This was possibly the world's first smartphone because it was a mobile phone, pager, fax machine, and PDA and It included a calendar, address book, clock, calculator, notepad, email..

Mobile broadband data – 3G The first 3G Mobile phone appeared on the market in Japan in the Tokyo region in May 2001. The most significant innovation was the incorporation of th e second chamber to realize videollamadas, that was to speak with a person and to see her/his at the same time. When you go to other country, the mobile phones change, and the phone rate is different and more expensive

This is the phone in the actuallity 4G

This smart phone is smaller than the first mobile phone. With this mobile phone, you can phone, send text messages,use whatsapp, watch videos, see photos, listen to music .... You can use this phone as a co mputer

This mobile phone has a lot of applications, imagine you have got and emergency and you haven´t batery, these smart phones have got a second batery to supply. You only write this code *3370# and you can use the phone

These are the parts and the icons in the 4G mobile phone
