Why do we get Hiccups?

why do we get hiccups

Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?

What are Hiccups?

Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.

Where did the Word Butterfly Come From?

Millie explained recently what etymology means, and fitting to this week’s theme of Jump! Into Biology, we are are asking ‘where did the word butterfly come from?’.
Who hasn’t seen a butterfly flitting by and  enjoyed seeing the flutter of its wings? But have you ever considered why it came to be called “butterfly”? Perhaps you have wondered whether there used to be a large number of yellow, butter-coloured butterflies who gave their name to the whole species?

Well, there is a nice little story attached to the name of the butterfly. In the past, there was a general belief that butterflies ate milk and butter. This probably came about because of the way that flies hover over any food at all that’s left out, and butterflies may have been seen hovering over uncovered pails of milk and butter. Not only that, but this belief developed to encompass the idea that butterflies were either sent out by witches to steal butter, or were in fact, witches themselves, disguised as butterflies. Quite why the witches were out to steal the butter, we don’t know!

Does Atlantis Exist, and Where Does the Name Originate?

Around 350 BC, the Greek philosopher Plato wrote about an island situated in front of the Pillars of Hercules, that disappeared under the sea in one day and one night. According to Plato, the capital of Atlantis was built on a hill and surrounded by rings of water, which were joined by tunnels large enough for a ship to sail through. A huge canal connected the outer rings of water to the ocean.
The possible existence of the island of  Atlantis has intrigued scholars and scientists over the centuries.

In 1800s a man called Ignatius Donnelly wrote a  bestselling book called Atlantis, the Antediluvian World. After studying flood history, Ignatius put forward the suggestion that Atlantis was not fiction, but the recording of a natural disaster.

Most modern academics insist that Plato created the story, and was perhaps inspired by events that happened during his lifetime, but that the island never existed.

The subject of dreams, of magical tales and many a search, Atlantis has long captured our imagination. But where did all of this spring from?
