Polymelia
Polymelia is a birth defect in which an affected individual has more than the usual number of limbs. It is a type of dysmelia. In humans and most land-dwelling vertebrates, this means having five or more limbs. The extra limb is most commonly shrunken and/or deformed. The term is from Greek πολυ- "many", μέλεα "limbs". Sometimes an embryo started as conjoined twins, but one twin degenerated completely except for one or more limbs, which end up attached to the other twin. Sometimes small extra legs between the normal legs are caused by the body axis forking in the dipygus condition. Notomelia (from Greek for "back-limb-condition") is polymelia where the extra limb is rooted along or near the midline of the back. Notomelia has been reported in Aberdeen Angus, Angus cattle often enough to be of concern to farmers. Cephalomelia (from Greek for "head-limb-condition") is polymelia where the extra limb is rooted on the head. Origin Tetrapod legs evolved in the Devonian or Ca ...

Birth Defect
A birth defect is an abnormal condition that is present at birth, regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many birth defects are believed to involve multiple factors. Birth defects may be visible at birth or dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysmelia
Dysmelia (from the Greek (), "bad" + (), "limb" + English suffix -ia) is a congenital disorder of a limb resulting from a disturbance in embryonic development. Types Dysmelia can refer to * missing ( aplasia) limbs: amelia (including tetraamelia), oligodactyly, congenital amputation e.g. tibial or radial aplasia * malformation of limbs: shortening (micromelia, rhizomelia or mesomelia), ectrodactyly, phocomelia, meromelia, syndactyly, brachydactyly, club foot * extra limbs: polymelia, polydactyly, polysyndactyly * others: hemimelia, symbrachydactyly Occurrence rate Birth defects involving limbs occur in 0.69 per 1000. Causes Dysmelia can be caused by * Inheritance of abnormal genes, e.g. polydactyly, ectrodactyly or brachydactyly, symptoms of deformed limbs then often occur in combination with other symptoms (syndromes) * external causes during pregnancy (thus not inherited), e.g. via amniotic band syndrome * teratogenic drugs (e.g. thalidomide, which cause ...

Aberdeen Angus
The Aberdeen Angus, sometimes simply Angus, is a Scotland, Scottish List of cattle breeds, breed of small beef cattle. It derives from cattle native to the Scottish counties, counties of Aberdeenshire (historic), Aberdeen, Banffshire, Banff, Kincardineshire, Kincardine and Angus, Scotland, Angus in north-eastern Scotland. In 2018 the breed accounted for over 17% of the beef production in the United Kingdom. The Angus is naturally Polled livestock, polled and solid black or red; the udder may be white. The cattle have been exported to many countries of the world; there are large populations in Australia, Canada, New Zealand, South America and the United States, where it has developed into two separate and distinct breeds, the American Angus and Red Angus. In some countries it has been selective breeding, bred to be taller than the native Scottish stock. Its conservation status worldwide is "not at risk"; in the United Kingdom the original Native Aberdeen Angus – cattle not i ...

Radiography
Radiography is an imaging technology, imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography. Similar techniques are used in airport security, (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and it is projected towards the object. A certain amount of the X-rays or other radiation are absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a X-ray detector, detector (either photographic film or a digital detector). The generation of flat two-dimensional images by this technique is called Projection radiography, projectional radiography. In computed tomography (C ...

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 conjoined 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 his aunt, the wife of his uncle Corrado 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 could not use it to 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 ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Monsters & Prodigies 14
A monster is a type of imaginary or fictional creature found in literature, folklore, mythology, fiction and religion. They are very often depicted as dangerous and aggressive, with a strange or grotesque appearance that causes terror and fear, often in humans. Monsters usually resemble bizarre, deformed, otherworldly and/or mutated animals or entirely unique creatures of varying sizes, but may also take a human form, such as mutants, ghosts, spirits, cannibals or zombies, among other things. They may or may not have supernatural powers, but are usually capable of killing or causing some form of destruction, threatening the social or moral order of the human world in the process. Animal monsters are outside the moral order, but sometimes have their origin in some human violation of the moral law (e.g. in the Greek myth, Minos does not sacrifice to Poseidon the white bull which the god sent him, so as punishment Poseidon makes Minos' wife, Pasiphaë, fall in love with the bul ...

Life The credit for detecting its value belongs to Gaston Paris, although his edition (1897) was partially anticipated by the editors of the ', who published some selections in the twenty-seventh volume of their Scriptores (1885). Ambroise followed Richard I as a noncombatant, and not improbably as a court-minstrel. He speaks as an eyewitness of the king's doings at Messina, in Cyprus, at the siege of Acre, and in the abortive campaign which followed the capture of that city. Commentary on his work Ambroise is surprisingly accurate in his chronology; though he did no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
