Martin Barry
Martin Barry (28 March 1802, Fratton, Portsmouth, Hampshire – 27 April 1855, Beccles, Suffolk), was a British physician who studied histology and embryology. Career He qualified as a doctor in Edinburgh in 1833, and then studied at the University of Heidelberg. He was elected a fellow of the Royal Society in 1840, and had the previous year, in 1839, been awarded the Society's Royal Medal for his work on embryology. He was the first to discover the segmentation of yolk in the mammalian ovum. He enunciated the doctrine that all cells were descended from an original mother cell by cleavage of the nucleus. One of his most fundamental discoveries, published in Philosophical Transactions in 1843, was that spermatozoa could sometimes be found inside the ovum. The note that Barry published was titled ''On the Penetration of Spermatozoa into the Interior of the Ovum''. This work, carried out with rabbits, influenced Theodor Ludwig Wilhelm Bischoff's theories concerning fertilisati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fratton
Fratton is a residential and formerly industrial area of Portsmouth in Hampshire, England. Victorian style terraced houses are dominant in the area, typical of most residential areas of Portsmouth. Fratton has many discount shops and "greasy spoon" cafes, as well as The Bridge Shopping Centre containing an Asda. History The name Fratton was once Froddington, a Saxon name which originally meant "Frodda's Farm" or "Frodda's village". A pub on Fratton Road is still named "The Froddington Arms". There is a commemorative plaque by the petrol station near Fratton Asda, marking where a bomb shelter was hit by a bomb on 10 January 1941, killing 80 people. Goldsmith's Farm and Fratton Common were part of the original small rural village originally called Froddington, the only visible evidence of this being the presence of a public house, "The Froddington Arms" on the western side of Fratton Road. Froddington was one of the three small settlements on Portsea Island mentioned in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Ludwig Wilhelm Bischoff
Theodor Ludwig Wilhelm von Bischoff (28 October 1807 in Hannover – 5 December 1882 in Munich) was a German physician and biologist. Biography He lectured on pathological anatomy at University of Heidelberg, Heidelberg (1835-1843) and held professorships in anatomy and physiology at University of Giessen, Giessen (1843-1855) and University of Munich, Munich, where he was appointed to the chair of anatomy and physiology in 1854. In 1843, Theodor von Bischoff was elected as member of the German Academy of Sciences. His most important contributions were made in embryology with a series of four exhaustive memoirs on the development of the mammalian ovum; published in 1842 (rabbit), 1845 (dog), 1852 (guinea pig), and 1854 (roe deer). His studies concerning animal metabolism by measuring urea were less successful, as was his research on the anatomy of skull and brain. He was elected a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1878. Selected works * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fellows Of The Royal Society Of Edinburgh
The Royal Society of Edinburgh (RSE) is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellowship of the Royal Society of Edinburgh, Fellows.

The Fellowship includes people from a wide range of disciplines: science and technology, arts, humanities, medicine, social science, business, and public service. History At the start of the 18th century, Edinburgh's intellectual climate fostered many clubs and societies (see Scottish Enlightenment). Though there were several that treated the arts, sciences and medicine, the most prestigious was the Society for the Improvement of Medical Knowledge, commonly referred to as the Medical Society of Edinburgh, co-founded by the mathematicia ...

19th-century English Medical Doctors
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm ce ...

Oscar Hertwig
Oscar Hertwig (21 April 1849 in Friedberg – 25 October 1922 in Berlin) was a German embryologist and zoologist known for his research in developmental biology and evolution. Hertwig is credited as the first person to observe sexual reproduction at the cellular level, by looking at the cells of sea urchins under the microscope. Biography Hertwig was the elder brother of zoologist-professor Richard Hertwig (1850–1937). The Hertwig brothers were the most eminent scholars of Ernst Haeckel (and Carl Gegenbaur) from the University of Jena. They were independent of Haeckel's philosophical speculations but took his ideas in a positive way to widen their concepts in zoology. Initially, between 1879 and 1883, they performed embryological studies, especially on the theory of the coelom (1881), the fluid-filled body cavity. These problems were based on the phylogenetic theorems of Haeckel, i.e. the biogenic theory (German = biogenetisches Grundgesetz), and the " gastraea theory" ...

Fertilisation
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a zygote and initiate its development into a new individual organism or offspring. While processes such as insemination or pollination, which happen before the fusion of gametes, are also sometimes informally referred to as fertilisation, these are technically separate processes. The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms, the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. History In antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic. In 1784, Spallanzani established the need of in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovum
The egg cell or ovum (: ova) is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non- motile). If the male gamete (sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized, the oosphere becomes the oospore. When egg and sperm fuse together during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism. History While the non-mammalian animal egg was obvious, the doctrine ''ex ovo omne vivum'' ("every living nimal comes froman egg"), associated with William Harvey (1578–1657), was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reproduced v ...
