Otto Deiters
Otto Friedrich Karl Deiters (; 15 November 1834 – 5 December 1863) was a German neuroanatomist. He was born in Bonn, studied at the University of Bonn, and spent most of his professional career in Bonn. He is remembered for his microscopic research of the brain and spinal cord. His name is lent to the "nucleus of Deiters", also called the lateral vestibular nucleus, and to "Deiters' cells", structures that are associated with outer hair cells in the cochlea of the inner ear. Deiters died in 1863 from typhoid fever at the age of 29. Before he died, Deiters provided the most comprehensive description of a nerve cell that was known to exist at the time. He identified the cells' axon, which he called an "axis cylinder", and its dendrites, which he referred to as protoplasmic processes. He postulated that dendrites must fuse to form a continuous network. After his death, in 1865, his work pertaining to nerve cells of the spinal cord was edited and published by anatomist Max Sc ...

Axon
An axon (from Greek ἄξων ''áxōn'', axis) or nerve fiber (or nerve fibre: see American and British English spelling differences#-re, -er, spelling differences) is a long, slender cellular extensions, projection of a nerve cell, or neuron, in Vertebrate, vertebrates, that typically conducts electrical impulses known as action potentials away from the Soma (biology), nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the peripheral nervous system, periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon. Axon dysfunction can be the cause of many inherited and acquired neurological disorders that affect both the Peripheral nervous system, peripheral and Central nervous system, central ne ...

University Of Bonn Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in th ...

19th-century German Physicians
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 ...

Prussian Physicians
Prussia (; ; Old Prussian: ''Prūsija'') was a Germans, German state centred on the North European Plain that originated from the 1525 secularization of the Prussia (region), Prussian part of the State of the Teutonic Order. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, History of Berlin, Berlin, decisively shaped the history of Germany. Prussia formed the German Empire when it united the German states in 1871. It was ''de facto'' dissolved by 1932 Prussian coup d'état, an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and ''de jure'' by Abolition of Prussia, an Allied decree in 1947. The name ''Prussia'' derives from the Old Prussians who were conquered by the Teutonic Knightsan organized Catholic medieval Military order (religious society), military order of Pru ...

Max Schultze
Max Johann Sigismund Schultze (25 March 1825 – 16 January 1874) was a German microscopic anatomist noted for his work on cell theory. Biography Schultze was born in Freiburg im Breisgau (Baden), son of the anatomist Karl August Sigismund Schultze (1795–1877). He studied medicine at Greifswald and Berlin, and was appointed an associate professor of anatomy at the university of Halle in 1854. Five years later he became a full professor of anatomy and histology and director of the Anatomical Institute at the University of Bonn. He died in Bonn on 16 January 1874; his successor at the anatomical institute being Adolph von La Valette-St. George. He was the older brother of obstetrician Bernhard Sigmund Schultze (1827–1919). He founded, in 1865, and edited the important "''Archiv für mikroskopische Anatomie''", to which he contributed many papers, and he advanced the subject generally, by refining on its technical methods. His works included: *''Beiträge zur Naturgeschichte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomist
Anatomy () is the branch of morphology concerned with the study of the internal structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine, and is often studied alongside physiology. Anatomy is a complex and dynamic field that is constantly evolving as discoveries are made. In recent years, there has been a significant increase in the use of ...

Protoplasm
Protoplasm (; ) is the part of a cell that is surrounded by a plasma membrane. It is a mixture of small molecules such as ions, monosaccharides, amino acids, and macromolecules such as proteins, polysaccharides, lipids, etc. In some definitions, it is a general term for the cytoplasm (e.g., Mohl, 1846), but for others, it also includes the nucleoplasm (e.g., Strasburger, 1882). For Sharp (1921), "According to the older usage the extra-nuclear portion of the protoplast 'the entire cell, excluding the cell wall''was called "protoplasm," but the nucleus also is composed of protoplasm, or living substance in its broader sense. The current consensus is to avoid this ambiguity by employing Strasburger's (1882) terms cytoplasm Kölliker (1863), originally as synonym for protoplasm''and nucleoplasm van Beneden (1875), or karyoplasm, used by Walther Flemming">Flemming (1878)''">karyoplasm">'term coined by Edouard Van Beneden">van Beneden (1875), or karyoplasm, used by Walther Flemming ...

Dendrite
A dendrite (from Ancient Greek language, Greek δένδρον ''déndron'', "tree") or dendron is a branched cytoplasmic process that extends from a nerve cell that propagates the neurotransmission, electrochemical stimulation received from other neural cells to the cell body, or soma (biology), soma, of the neuron from which the dendrites project. Electrical stimulation is transmitted onto dendrites by upstream neurons (usually via their axons) via synapses which are located at various points throughout the dendritic tree. Dendrites play a critical role in integrating these synaptic inputs and in determining the extent to which action potentials are produced by the neuron. Structure and function Dendrites are one of two types of cytoplasmic processes that extrude from the cell body of a neuron, the other type being an axon. Axons can be distinguished from dendrites by several features including shape, length, and function. Dendrites often taper off in shape and are shorter, ...
