Krista And Tatiana Hogan
Krista and Tatiana Hogan (born October 25, 2006) are Canadians who are conjoined craniopagus twins. They are joined at the head and share a brain. They were born in Vancouver, British Columbia, and are the only unseparated conjoined twins of that type currently alive in Canada. They live with their mother, Felicia Simms, in Vernon, British Columbia, have two sisters and a brother and often travel to Vancouver for care at BC Children's Hospital and Sunny Hill Health Centre for Children. Birth The twins were given a 20 percent chance of survival at birth. At birth at B.C. Women's Hospital & Health Centre, they were described as "wriggly, vigorous and very vocal". They weighed 12 and a half pounds when they were born by Caesarean section. Early infant life Tatiana is smaller and less robust than Krista. Tests on them in April 2007 showed that Tatiana's heart was working harder than Krista's and that she had high blood pressure because of it—Tatiana's heart was supplying part of ...

Thalami
The thalamus (from Greek θάλαμος, "chamber") is a large mass of gray matter located in the dorsal part of the diencephalon (a division of the forebrain). Nerve fibers project out of the thalamus to the cerebral cortex in all directions, allowing hub-like exchanges of information. It has several functions, such as the relaying of sensory signals, including motor signals to the cerebral cortex and the regulation of consciousness, sleep, and alertness. Anatomically, it is a paramedian symmetrical structure of two halves (left and right), within the vertebrate brain, situated between the cerebral cortex and the midbrain. It forms during embryonic development as the main product of the diencephalon, as first recognized by the Swiss embryologist and anatomist Wilhelm His Sr. in 1893. Anatomy The thalamus is a paired structure of gray matter located in the forebrain which is superior to the midbrain, near the center of the brain, with nerve fibers projecting out to the ...

Sibling Duos
A sibling is a relative that shares at least one parent with the subject. A male sibling is a brother and a female sibling is a sister. A person with no siblings is an only child. While some circumstances can cause siblings to be raised separately (such as foster care), most societies have siblings grow up together. This causes the development of strong emotional bonds, with siblinghood considered a unique type of relationship unto itself. The emotional bond between siblings is often complicated and is influenced by factors such as parental treatment, birth order, personality, and personal experiences outside the family. Medically, a full sibling is a first-degree relative and a half sibling is a second-degree relative as they are related by 50% and 25% respectively. Definitions The word ''sibling'' was reintroduced in 1903 in an article in '' Biometrika'', as a translation for the German ''Geschwister'', having not been used since 1425. Siblings or full siblings ( 'full'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Vernon, British Columbia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Conjoined Twins
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 ...

Ladan And Laleh Bijani
Ladan and Laleh Bijani (Persian: ; 17 January 1974 – 8 July 2003) were Iranian conjoined twin sisters. They were joined at the head and died soon after their complicated surgical separation. Coincidentally, the twins were born a century to the day after the deaths of Chang and Eng Bunker, also conjoined twins, famously known as the "original" Siamese twins. Biography They were born in Firuzabad, a city in southwest Iran, to Dadollah Bijani and Maryam Safari, members of a farming family from the nearby Lohrasb village. The Bijani sisters were lost in a hospital in 1979 after the doctors responsible for them had to suddenly leave for the United States during the revolution in Iran. The Bijanis' parents did not find the sisters again until several years later in the city of Karaj near Tehran, where Alireza Safaian had adopted them. While in his custody, Safaian attempted to protect them by sequestering them from the world as best as he could. In 1996, after years of search ...

Polycephaly
Polycephaly is the condition of having more than one head. The term is derived from the Greek stems ''poly'' (Greek: "πολύ") meaning "many" and ''kephalē'' (Greek: "κεφαλή") meaning "head". A polycephalic organism may be thought of as one being with a supernumerary body part, or as two or more beings with a shared body. Two-headed animals (called bicephalic or dicephalic) and three-headed (tricephalic) animals are the only type of multi-headed creatures seen in the real world, and form by the same process as conjoined twins from monozygotic twin embryos. In humans, there are two forms of twinning that can lead to two heads being supported by a single torso. In dicephalus parapagus dipus, the two heads are side by side. In craniopagus parasiticus, the two heads are joined directly to each other, but only one head has a functional torso. Survival to adulthood is rare, but does occur in some forms of dicephalus parapagus dipus. There are many occurrences of multi-h ...

Sleep Apnea
Sleep apnea, also spelled sleep apnoea, is a sleep disorder in which pauses in breathing or periods of shallow breathing during sleep occur more often than normal. Each pause can last for a few seconds to a few minutes and they happen many times a night. In the most common form, this follows loud snoring. There may be a choking or snorting sound as breathing resumes. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired during the day. In children, it may cause hyperactivity or problems in school. Sleep apnea may be either obstructive sleep apnea (OSA), in which breathing is interrupted by a blockage of air flow, central sleep apnea (CSA), in which regular unconscious breath simply stops, or a combination of the two. OSA is the most common form. OSA has four key contributors; these include a narrow, crowded, or collapsible upper airway, an ineffective pharyngeal dilator muscle function during sleep, airway narrowing during sleep and ...

Brainstem
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the diencephalon is included in the brainstem. The brainstem is very small, making up around only 2.6 percent of the brain's total weight. It has the critical roles of regulating cardiac, and respiratory function, helping to control heart rate and breathing rate. It also provides the main motor and sensory nerve supply to the face and neck via the cranial nerves. Ten pairs of cranial nerves come from the brainstem. Other roles include the regulation of the central nervous system and the body's sleep cycle. It is also of prime importance in the conveyance of motor and sensory pathways from the rest of the brain to the body, and from the body back to t ...

Lori And George Schappell
Lori and George Schappell (born as Lori and Dori Schappell; September 18, 1961) are conjoined twins. George has performed as a country singer. Careers George has designed support equipment for people with physical disabilities, including a specialized wheelchair and a mobility aid for dogs. As country singer Reba, George has performed widely in the United States and visited Germany and Japan and in 1997, won an L.A. Music Award for Best New Country Artist. He sang "Fear of Being Alone" over the credits of '' Stuck on You'', a comedy film about a pair of fictitious conjoined twins. Lori acts as George's facilitator. She works in a laundry, arranging her workload around his singing commitments. She says that, as a fan of his, she pays to attend concerts, just like all the other fans, simply making herself quiet and "invisible" while he is performing.
