I Neuroni

I neuroni rappresentano l'elemento fondamentale del tessuto nervoso e sono specializzati in diverse funzioni. Essi possono essere motori, sensoriali o associativi. I neuroni motori inviano segnali dal sistema nervoso agli organi periferici, mentre i neuroni sensoriali raccolgono stimoli dalla periferia e li trasmettono al sistema nervoso centrale.

The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.

Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

Caratteristiche

Asia is the world's largest continent of the seven continents in size, as it covers one-third of the earth's surface.

It includes 50 countries, and it is the most populated continent, 60% of the total population of the Earth lives here.

Conducibilità

Asia houses the highest point on earth.
Name this summit and write down how tall it is.

Eccitabilità

Name as many as you can out of the 48 countries located in Asia.

Write down the capitals too.

Neuroni Associativi

Antarctica is not only the coldest place on Earth but also the highest, driest, windiest and emptiest, completely covered with ice.

75% of the world's ice and 70% of the Earth's fresh water is located here.

Summer months of December to February give 24 hours of light, while the winter months of late March to late September are pitch dark the whole day.

There are no permanent inhabitants, except for scientists maintaining research stations in Antarctica.

Neuroni Motori

You can find on this continent:

Trasmettono gli impulsi dal sistema nervoso agli organi periferici

There are 12 countries that make up South America.

Name as many of you can! Don't forget about their capitals.

Neuroni Sensoriali

North America has five time zones and it is the only continent with every type of climate.

North America was named after the explorer Amerigo Vespucci and is also known as the 'New World'.

The world's largest sugar exporter among the seven continents - Cuba - also called the 'sugar bowl of the world' is located here.

Trasmettono gli stimoli dalla periferia al sistema nervoso centrale

There are 23 countries that make up North America.

Name as many of you can! Don't forget about their capitals.

I NERVI

Australia is the world's smallest continent and is also known as an 'island continent' as it is surrounded by water on all sides.
It includes 14 countries and it is the least populated continent.

Its name comes from the Latin word 'australis' meaning 'southern' because it lies entirely on the south of the equator.

Portano segnali elettrici tra il cervello o il midollo spinale e altre parti del corpo

The largest coral reef can be found here.
Name this coral reef, add its length and mention what type of coral is it.

Sono formati da fasci di fibre nervose (assoni)

Out of 14, how many countries you can name?

How about these countries' capitals?

Sono formati da:

Europe is separated from Asia by the Ural mountains and the Caspian Sea.

It is surrounded by water on three sides: Mediterranean Sea in the south, Atlantic Ocean in the west, and the Arctic Ocean in the north.

Three-fourth of the world's potatoes grow in Europe.

Europe is a large region, with several major rivers that connect its many countries. There are five primary rivers in Europe, and one of them flows through 10 countries, more than any other river in the world.

Name these rivers.

Europe is one of the smallest continents, yet it is home to some of the largest mountain ranges.

About 20% of the total landmass of the continent is considered mountainous.

Name the 5 longest mountain ranges in Europe.
