Types of joints in the human body - human body for kids

Human body moves in many different ways.
You can bend, stretch, turn, and twist.
You can move because your bones move at your joints, places where your bones meet.
But your bones can’t move by themselves—they need something to pull at them. 
This job is done by your muscles, which are joined to your bones in order to move them.
There are many joints that help your body move.
When you turn your head, bend your knees, or twist your wrists, your joints are in action.
Some joints, such as those in your skull, do not move. These are called fixed joints.
Each of the other kinds of joints does a specific type of movement.

Types of joints in the human body

- Ball and socket joints give you the most movement.
The round end of one bone fits into a hollow part of another bone. Examples are your hip joints and shoulder joints.

- Hinge joints work like a door on a hinge.
Movement in hinge joints is only in two directions. Your knees and elbows have hinge joints.

- Pivot joints allow parts of your body to twist.
Your head moves from side to side because it rests on a pivot joint at the top of your spine. In the same way, you can turn your hands over by flipping your wrists.

- Gliding joints are one of the simplest kinds of joints.
They allow a sliding movement when two pieces of bone come together. There are gliding joints on your backbone where the ribs meet the vertebrae.

Morse Code for Kids and Morse Code Alphabet

In 1832, an American artist sailed home from Europe. He had spent some time painting in Europe and hoped to sell his pictures when he arrived home. His name was Samuel Morse.
The journey on the ship was to change Samuel Morse’s life.

He met a young chemist from Boston, named Charles Jackson, who showed him how an electromagnet works. Morse became interested in electricity and in the idea of sending messages along electric wires.
Samuel Morse was one of the first people to make an electric telegraph. 
An electric telegraph uses an electric current to send messages along a wire.

Operators of this electric telegraph machine sent messages down the line in Morse Code.
Morse Code Alphabet This telegraph was not what made Morse famous. He gave his name to the code of dots and dashes which he invented.
Until this time, most long distance messages were sent by semaphore.
The problem with the electric telegraph was that an electric current can be arra…

Heliograph - Communicating by light

What is Heliograph? Sometimes when you are in open country, you may catch a flash of sunlight on the windshield of a car many miles away.
The windshield acts like a mirror and reflects the light.
You have probably shone a flashlight beam against a wall or ceiling and watched the spot of light.
Cover the mirror or flashlight with your hand, and the light disappears.

Put these two ideas together, and you have one of the oldest ways of communicating in the world—signalling by the light of the sun.
The ancient Greeks signaled to each other in this way.
They used an instrument called a heliograph. 
The name comes from the ancient Greek words for “sun” and “writing.”
A heliograph can be seen up to 30 miles (48 kilometers) away on a clear day without a telescope. The modern heliograph is mounted on a tripod, like a camera.
It can turn in any direction.
The mirror flashes when it is directed at the sun and can then be dipped away or covered with a shutter.
If the signaler wants to send a mess…

Semaphore Alphabet

Throughout history, armies and navies have sent messages across battlefields.
Simple orders like “Advance” or “Retreat” could be given by bugle calls or cannon-fire.
But sending reports of the battle back to headquarters needed a different system. During the 1790’s, a Frenchman called Claude Chappe invented a signaling system called semaphore. This was a system of sending signals by means of two jointed arms at the tops of tall posts. These arms could be moved to different positions to show different letters of the alphabet. Each semaphore station was built on a hill so that it could be seen, using a telescope, from the next station in any direction. In this way, messages could be relayed over long distances from one station to the next.
Semaphore stations on the coast would send messages to ships at sea. On the battlefield, there might not be a semaphore station, but messages could be sent by stationing signalers with large flags on nearby hills.
They used the same code as the semaph…
