When a girl reaches puberty, the hymen becomes stretchy. The hymen may be damaged by girls fall directly onto sharp objects .Sexual intercourse is another easy way to damage the hymen along with horseback riding and biking. A woman's hymen can also break while playing some sports
These animals all have a hymen:
There are many more animals which have hymens, but not all are listed here.
When a fetus is developing, there is no vaginal opening. The hymen comes from the skin covering the vagina at that time.
In young babies, the hymen is thick and pink. This is because the mother is giving the baby hormones through breast feeding which keeps it thick. In adolescent girls, the hymen becomes thin, smooth and delicate because she has stopped taking in hormones. The hymen becomes very sensitive and can easily cause pain if touched. From puberty, the hymen gets thicker again and becomes pale pink. This is because of the hormone estrogen.
Maidenhead
Maidenhead is a town in England in Berkshire. About 60,000 people live in the town. The town is about 25 miles (41 kilometres) from London. It is named after a wharf that was built there in 1297. It lies on the River Thames.
G-spot
The Gräfenberg spot (usually called G-spot) is defined as a highly sensitive area near the entrance inside of the human vagina. It is believed to be a part of the urethral sponge. Some people believe it is a bundle of nerves in the female human reproductive system. If the area is stimulated, this can cause pleasurable sensations, female ejaculation and a strong orgasm in some women. Some doctors and researchers who specialize in the anatomy of women say that there is no anatomical evidence for the spot.
The "G-spot" concept was named by Addiego and others in 1981 or by Beverly Whipple and others in 1982. It is named after the German gynaecologist, Ernst Gräfenberg. Gräfenberg wrote first about "The Role of Urethra in Female Orgasm" in 1950. A book was first published about the G-spot in 1982, called "The G Spot and Other Recent Discoveries About Human Sexuality", by three authors from the United States: Alice Kahn Ladas, a psychologist; Beverly Whipple, a registered nurse and sex counselor; and John D. Perry, a psychologist.
Although typically described as near the entrance inside of the vagina, reports of the G-spot's location vary and therefore it has no specific place to be found. However, there are two methods which are used to find it:
Some women say that they have "deeper" orgasms when the G-spot is stimulated. One research team experimented with the vagina by trying to touch the G-spot in certain places under experimental conditions; they found that in most cases, women had a sensitive area near the front of the vagina.
Some people, including doctors, do not believe that the G-spot exists. When the book "The G Spot and Other Recent Discoveries About Human Sexuality" was published in 1982, there was significant criticism. Some people who are not doctors simply say that it is a "highly sensitive area" in the vagina.
Scientists have carried out tests trying to find the G-spot and have not found any consistent or definitive evidence of it, and most of them believe that, if it does exist, it is an extension of the clitoris.
Skene's gland
Skene's glands (also called lesser vestibular glands or paraurethral glands) are glands in the upper wall of the vagina. They empty into the urethra. Their location is known as the Gräfenberg spot. In males, their homologue is the prostate gland.
The glands are named after the person who described them first, Alexander Skene. He was a physician.
Bartholin's gland
The Bartholin's glands are two glands found slightly below and to the left and right of the opening of the vagina in women.
They were first found in the 17th century, by the Danish anatomist, Caspar Bartholin the Younger (1655-1738).
The glands secrete mucus to make sexual intercourse easier. Bartholin's glands secrete relatively minute amounts (one or two drops) of fluid when a woman is sexually aroused.
Sometimes, the Bartholin's glands become infected and can be swollen or painful. This can be treated by a doctor with antibiotics.
Gland
A gland is a group of cells in the body which make substances such as hormones. They are in humans and other animals, and in plants.
Examples of glands in humans are:
Sevastopol
Sevastopol (, formerly called Sebastopol) is a large seaport and city. It is on the Crimean Peninsula, on the north side of the Black Sea. 380,000 people live in the city. It was started in 1783. The port was shared by naval forces of Ukraine and Russia until 2014 when Russia took control.
Aegukka
"Aegukka", Korean for "Patriotic Song", is North Korea's national anthem. To celebrate the country's independence from imperial Japan, it was written by Pak Se-yong and composed by Kim Won-gyun, then it was adopted in 1947 shortly after.
It should not be confused with South Korea's anthem, which has the same name but uses a different romanisation scheme. It is sometimes also known by the first bit of the song, "Achhimŭn pinnara" (아침은 빛나라), meaning "Let Morning Shine".
Aegukga
Aegukga (Aeguk-kka; 애국가 ; 愛國歌), meaning The Patriotic Song is the national anthem of the Republic of Korea (South Korea). It should not be confused with North Korea's anthem, which has the same name.
The song is sang in the order of 1, refrain, 2, refrain, 3, refrain, 4, refrain.
Conquest
The word conquest can refer to different things:
Sunni Islam
Sunni Islam () is the largest branch of Islam. They are the branch of Islam that came through the Rashidun Empire, which started with Abu Bakr and ended by Ali ibn Abi Talib. Sunni beliefs are based on the Qu'ran and the Kutub al-Sittah. Sunnis make up around 90% of all Muslims. With approximately 1.8 billion followers, it is the largest religious denomination of any religion in the world. Catholicism is the second-largest. There are four sub-groups within Sunni Islam; Malikis, Hanafis, Hanbalis and Shafi'is.
Adherents of Sunni Islam are Sunnis or Sunnites. The word "Sunni" comes from the word sunna (), which means the tradition of the prophet of Islam, Muhammad. Sunnis are also called "ahl as-sunnah wa l-jamāʻah" (), which means people of tradition and congregation; this means that the Sunnis are united.
Hunting
Hunting is going out to find and kill animals. Animals and some humans, hunt for food. People have hunted at least since the stone age. They used spears, and now people mostly use guns and bows. Some people kill the animals for fur, to make clothes and shelter, or to decorate their homes, or to sell. Fox hunting is sometimes a sport.
Many places have rules that limit hunting. Hunting can be good by keeping animal populations from getting too high. Hunting too much, though, can kill off species of animals, making them extinct. Hunting once made the dodo, a bird, become extinct.
Before they invented herding people got meat by hunting. Boar hunting and fox hunting became became popular in early modern times. Another form of hunting is not to use guns, bows and arrows or spears, but by animal trapping.
Tycho Brahe
Tycho Brahe (14 December 1546 — 24 October 1601) was an astronomer from Denmark. He observed the night sky before the invention of the telescope. He built a large observatory called Uraniborg on the island of Hven in Denmark.
He discovered that the universe outside the Solar System could change when he studied a supernova and a comet. Johannes Kepler was his assistant. Tycho made very careful observations of the planets. When Tycho died in 1601, Kepler continued Tycho's work.
Tycho was not a modern scientist. He believed in astrology, and his astronomy was a strange mixture of scientific observation and religious belief. Although he rejected the Ptolemaic system, he also rejected the Copernican system. He developed a geocentric theory that imagined the Sun and Moon orbited the Earth, but the other planets orbited the Sun.
