Eye Development
Eye formation in the human embryo begins at approximately three weeks into embryonic development and continues through the tenth week.Ort, D., David, H."Development of the Eye" Retrieved 22 April 2015. Cells from both the mesodermal and the ectodermal tissues contribute to the formation of the eye. Specifically, the eye is derived from the neuroepithelium, surface ectoderm, and the extracellular mesenchyme which consists of both the neural crest and mesoderm. Neuroepithelium forms the retina, ciliary body, iris, and optic nerves. Surface ectoderm forms the lens, corneal epithelium and eyelid. The extracellular mesenchyme forms the sclera, the corneal endothelium and stroma, blood vessels, muscles, and vitreous. The eye begins to develop as a pair of optic vesicles on each side of the forebrain at the end of the 4th week of pregnancy. Optic vesicles are outgrowings of the brain which make contact with the surface ectoderm and this contact induces changes necessary for further de ...

Moscow ( , US chiefly ; rus, links=no, Москва, r=Moskva, p=mɐskˈva, a=Москва.ogg) is the capital and largest city of Russia. The city stands on the Moskva River in Central Russia, with a population estimated at 13.0 million residents within the city limits, over 17 million residents in the urban area, and over 21.5 million residents in the metropolitan area. The city covers an area of , while the urban area covers , and the metropolitan area covers over . Moscow is among the world's largest cities; being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its name. When the Grand Duchy of Moscow evolved into the Tsardom of Russia, Moscow remained the political and economic center for most of the Tsardom's history. When th ...

In religious belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and consequently a public cult of veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. While the English word ''saint'' originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", referring to the Jewish tzadik, the Islamic walī, the Hindu rishi or Sikh g ...

Nikolai Koltsov
Nikolai Konstantinovich Koltsov (russian: Николай Константинович Кольцов; July 14, 1872 – December 2, 1940) was a Russian biologist and a pioneer of modern genetics. Among his students were Nikolay Timofeeff-Ressovsky, Vladimir Pavlovich Efroimson, A.S. Serebrovsky, and Nikolay Dubinin. Along with his students, he demonstrated the fine structure of genes, and examined the structure of the cell and pioneered the idea of a cytoskeleton. His career was cut short in Stalinist Russia due to the entanglement of Marxist ideology and interpretations that genetics was a science that supported racism, fascism and eugenics. He died unexpectedly following government persecution and there are allegations that he was executed. Biography Koltsov was born in a well-to do family and graduated from Moscow University in 1894 and was a professor there (1895–1911). He established and directed the Institute of Experimental Biology in the middle of 1917, just before the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petr Sushkin
Petr Petrovich Sushkin (russian: Петр Петрович Сушкин; 27 January 1868 – 17 September 1928) was a Russian ornithologist who specialised on comparative anatomy, and evolution of birds, particularly of the birds of prey. Sushkin was born in Tula, Russia, in a merchant family. He studied at the Tula Classical Gymnasium (1877-1885) graduating with a silver medal before going on to Moscow University in 1885. He graduated in 1890 and joined the staff of the Leningrad Zoological Museum in 1898. He studied ornithology under Mikhail Menzbier and his dissertation in 1897 was on the morphology of the skeleton of birds, specifically of the kestrel. He conducted surveys in the Ufa province in 1891 and Kazakhstan in 1898. His studies on the birds of southeastern Russia, Siberia and the Altai Mountains were published in several monographs. Sushkin visited European museums from 1899 to 1900 and worked on his doctoral dissertation on the birds of prey. He became a professor at M ...

Limb Bud
The limb bud is a structure formed early in vertebrate limb development. As a result of interactions between the ectoderm and underlying mesoderm, formation occurs roughly around the fourth week of development. In the development of the human embryo the upper limb bud appears in the third week and the lower limb bud appears four days later. The limb bud consists of undifferentiated mesoderm cells that are sheathed in ectoderm. As a result of cell signaling interactions between the ectoderm and underlying mesoderm cells, formation of the developing limb bud occurs as mesenchymal cells from the lateral plate mesoderm and somites begin to proliferate to the point where they create a bulge under the ectodermal cells above. The mesoderm cells in the limb bud that come from the lateral plate mesoderm will eventually differentiate into the developing limb’s connective tissues, such as cartilage, bone, and tendon. Moreover, the mesoderm cells that come from the somites will eventually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limb Development
Limb development in vertebrates is an area of active research in both developmental and evolutionary biology, with much of the latter work focused on the transition from fin to limb. Limb formation begins in the morphogenetic limb field, as mesenchymal cells from the lateral plate mesoderm proliferate to the point that they cause the ectoderm above to bulge out, forming a limb bud. Fibroblast growth factor (FGF) induces the formation of an organizer at the end of the limb bud, called the apical ectodermal ridge (AER), which guides further development and controls cell death. Programmed cell death is necessary to eliminate webbing between digits. The limb field is a region specified by expression of certain Hox genes, a subset of homeotic genes, and T-box transcription factors – Tbx5 for forelimb or wing development, and Tbx4 for leg or hindlimb development. Establishment of the forelimb field (but not hindlimb field) requires retinoic acid signaling in the developing trunk of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otic Vesicle
Otic vesicle, or auditory vesicle, consists of either of the two sac-like invaginations formed and subsequently closed off during embryonic development. It is part of the neural ectoderm, which will develop into the membranous labyrinth of the inner ear. This labyrinth is a continuous epithelium, giving rise to the vestibular system and auditory components of the inner ear. During the earlier stages of embryogenesis, the otic placode invaginates to produce the otic cup. Thereafter, the otic cup closes off, creating the otic vesicle. Once formed, the otic vesicle will reside next to the neural tube medially, and on the lateral side will be paraxial mesoderm. Neural crest cells will migrate rostral and caudal to the placode. The general sequence in formation of the otic vesicle is relatively conserved across vertebrates, although there is much variation in timing and stages. Patterning during morphogenesis into the distinctive inner ear structures is determined by homeobox trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
