Parasitic Twin
A parasitic twin, also known as an asymmetrical or unequal conjoined twin, is the result of the processes that also produce vanishing twins and conjoined twins, and may represent a continuum between the two. Parasitic twins occur when a twin embryo begins developing in utero, but the pair does not fully separate, and one embryo maintains dominant development at the expense of its twin. Unlike conjoined twins, one ceases development during gestation and is vestigial to a mostly fully formed, otherwise healthy individual twin. The undeveloped twin is defined as parasitic, rather than conjoined, because it is incompletely formed or wholly dependent on the body functions of the complete fetus. The independent twin is called the autosite. Variants * Conjoined parasitic twins joined at the head are described as craniopagus or cephalopagus, and occipitalis if joined in the occipital region or parietalis if joined in the parietal region. * ''Craniopagus parasiticus'' is a general ter ...

Conjoined Twin
Conjoined twins – sometimes popularly referred to as Siamese twins – are twins joined ''in utero''. A very rare phenomenon, the occurrence is estimated to range from 1 in 49,000 births to 1 in 189,000 births, with a somewhat higher incidence in Southwest Asia and Africa. Approximately half are stillborn, and an additional one-third die within 24 hours. Most live births are female, with a ratio of 3:1. Two theories exist to explain the origins of conjoined twins. The more generally accepted theory is ''fission'', in which the fertilized egg splits partially. The other theory, no longer believed to be the basis of conjoined twinning, is ''fusion'', in which a fertilized egg completely separates, but stem cells (which search for similar cells) find similar stem cells on the other twin and fuse the twins together. Conjoined twins share a single common chorion, placenta, and amniotic sac, although these characteristics are not exclusive to conjoined twins, as there are some monozyg ...

Naples
Naples (; it, Napoli ; nap, Napule ), from grc, Νεάπολις, Neápolis, lit=new city. is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 909,048 within the city's administrative limits as of 2022. Its province-level municipality is the third-most populous metropolitan city in Italy with a population of 3,115,320 residents, and its metropolitan area stretches beyond the boundaries of the city wall for approximately 20 miles. Founded by Greeks in the first millennium BC, Naples is one of the oldest continuously inhabited urban areas in the world. In the eighth century BC, a colony known as Parthenope ( grc, Παρθενόπη) was established on the Pizzofalcone hill. In the sixth century BC, it was refounded as Neápolis. The city was an important part of Magna Graecia, played a major role in the merging of Greek and Roman society, and was a significant cultural centre under the Romans. Naples ser ...

Vestigial Twin
A vestigial twin is a form of parasitic twinning, where the parasitic "twin" is so malformed and incomplete that it typically consists entirely of extra limbs or organs. It also can be a complete living being trapped inside the host person, however the parasitic twin is anencephalic and lacks consciousness. This phenomenon occurs when a fertilized ovum or partially formed embryo splits incompletely. The result can be anything from two whole people joined by a bit of skin (conjoined twins), to one person with extra body parts belonging to the vestigial twin. Most vestigial limbs are non-functional, and although they may have bones, muscles and nerve endings, they are not under the control of the host. The possession of six or more digits on the hands and feet (polydactyly) usually has a genetic or chromosomal A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packagi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudy Santos
Rudy Santos (born 1953), also known by his stage name Octoman, is a man from the Philippines who has a rare condition known as parasitic twin. He is the oldest person ever recorded with this condition. Remaining from his parasitic sibling are an extra leg and couple of arms, including shoulders and an extra pair of nipples, all of them attached to Santos's pelvis and protruding from his abdomen. Also, an undeveloped head is attached to his sternum, presenting an incipient ear and a patch of hair. Additionally, Santos's own right leg is severely deformed, ending on a stump at the height of the knee, preventing him from walking without the use of crutches. History Belonging to an extremely poor family, during the 1970s and 1980s, Santos earned a living by appearing in freak shows, but during the late 1980s, he retired himself into seclusion, plunging into ten years of extreme poverty. In 2008, he was examined by a Filipino expert in separation of conjoined twins Conjoined twins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lazarus And Joannes Baptista Colloredo
Lazarus Colloredo and Joannes Baptista Colloredo (1617 – after 1646) were Italian conjoined twins who toured freak shows in 17th-century Europe. They were born in Genoa, Italy. Physical condition The upper body and left leg of Joannes Baptista (named after John the Baptist) stuck out of his mobile brother, Lazarus. He did not speak, kept his eyes closed and mouth open all the time, and was a parasitic twin. According to a later account by Copenhagen anatomist Thomas Bartholinus, if someone pushed the breast of Joannes Baptista, he moved his hands, ears, and lips. Entertainment career To make a living, Lazarus toured around Europe and visited at least Basel, Switzerland, and Copenhagen, Denmark, before he arrived in Scotland in 1642 and later visited the court of Charles I of England. He also visited Danzig (Gdańsk), the Ottoman Empire, and toured Germany and Italy in 1646. Private life Contemporary accounts described Lazarus as courteous and handsome, but for his ...

Lakshmi Tatma
Lakshmi Tatma is an Indian girl born in 2005 in a village in Araria district, Bihar, with "4 arms and 4 legs." She was actually one of a pair of ischiopagus conjoined twins, one of which was headless because its head had atrophied and chest had not fully developed in the womb, causing the appearance of one child with four arms and four legs. She has undergone surgery to remove these extra limbs. Background Lakshmi's father, Shambhu, and mother, Poonam, were day laborers who earned less than 40 rupees per day and were unable to afford a separation surgery for their daughter. The daughter was named after Lakshmi, the Hindu goddess of wealth (who is depicted as four-armed). The girl was sometimes an object of worship as an incarnation of the goddess; by the age of two, she was known all over India. At one point, a circus offered the couple money to buy Lakshmi as a sideshow, which forced the family into hiding. At the time of being found by Sharan Patil, the girl was suffering f ...

Frank Lentini
Francesco "Frank" Lentini (May 18, 1889 − September 21, 1966) was an Italian-American sideshow performer who toured with numerous circuses. Born with a parasitic twin, Lentini had three legs. Early life Lentini was born at 8 Gintoli Street, Rosolini, Sicily, on May 18, 1889. Delivered by midwife Maria Alberino, he was the fifth of 12 children (seven sisters and five brothers) in his family. Disgraced initially, his parents gave him into the care of the wife of his uncle Corrido Falco. At four months old he was sent to be examined by a specialist in Naples. By age five he was playing with other children and was able to straighten his third leg, but not walk. He became known for having three legs, four feet, and two sets of genitals. Lentini was born with a parasitic twin. The twin was attached to his body at the base of his spine and consisted of a pelvic bone, a rudimentary set of male genitalia, and a full-sized leg extending from the right side of his hip, with a small foot pr ...

Dipygus
Dipygus is a severe congenital deformity where the body axis forks left and right partway along the torso with the posterior end (pelvis and legs) duplicated. Myrtle Corbin was a dipygus; she married and had five children. In human cases, the inner two of the four hindquarters develop much smaller than normal. This is a type of "teras catadidymum" ("monster twinned below"). Another sort of deformity with extra legs can happen from a degenerated conjoined twin, as may have happened with Frank Lentini with his third leg. Signs Dipygus manifests as duplicated lower limbs and could include additional organs or bodily structures. Causes Dipygus is caused by genetic, environmental, or teratogenic Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology. The related ... factors. It occurs early in intraut ...

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus '' Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbidae
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated junglefowl species, with attributes of wild species such as the grey and the Ceylon junglefowl that are originally from Southeastern Asia. Rooster or cock is a term for an adult male bird, and a younger male may be called a cockerel. A male that has been castrated is a capon. An adult female bird is called a hen and a sexually immature female is called a pullet. Humans now keep chickens primarily as a source of food (consuming both their meat and eggs) and as pets. Traditionally they were also bred for cockfighting, which is still practiced in some places. Chickens are one of the most common and widespread domestic animals, with a total population of 23.7 billion , up from more than 19 billion in 2011. There are more chickens in the world than any other bird. There are numerous cultural references to chickens – in myth, folklore and religion, and in language and literature.
