History Of The Location Of The Soul
The search for a hypothetical soul and its location have been a subject of much speculation throughout history. In early medicine and anatomy, the location of the soul was hypothesized to be located within the body. Aristotle and Plato understood the soul as a corporeal form but closely related to the physical world. The Hippocratic Corpus chronicles the evolution of thought that the soul is located within the body and is manifested in diseased conditions. Later, Galen explicitly used Plato's description of the corporeal soul to physical locations in the body. The logical (λογιστικός) in the brain, the spirited (θυμοειδές) in the heart, and the appetitive (ἐπιθυμητικόν) in the liver. Da Vinci had a similar approach to Galen, locating the soul, or s''senso comune,'' as well as the ''imprensiva'' (intellect) and ''memoria'' (memory) in different ventricles of the brain. Today neuroscientists and other fields of science that deal with the body and the mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thymos
''Thumos'' (also commonly spelled 'thymos'; grc-gre, θυμός) is the Ancient Greek concept of "spiritedness" (as in "a spirited stallion" or "spirited debate"). The word indicates a physical association with breath or blood and is also used to express the human desire for recognition. It is not a somatic feeling, as nausea and giddiness are. History In Homer's works, ''thumos'' was used to denote emotions, desire, or an internal urge. ''Thumos'' was a permanent possession of living man, to which his thinking and feeling belonged. When a Homeric hero is under emotional stress, he may externalize his ''thumos'' and converse with or scold it.Long, A. A. Psychological Ideas in Antiquity. In: ''Dictionary of the History of Ideas''. 1973-74 003br>link Plato's '' Phaedrus'' and his later work '' The Republic'' discuss ''thumos'' as one of the three constituent parts of the human psyche.

Classical Element
Classical elements typically refer to earth, water, air, fire, and (later) aether which were proposed to explain the nature and complexity of all matter in terms of simpler substances. Ancient cultures in Greece, Tibet, and India had similar lists which sometimes referred, in local languages, to "air" as "wind" and the fifth element as "void". These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as cosmology. Sometimes these theories overlapped with mythology and were personified in deities. Some of these interpretations included atomism (the idea of very small, indivisible portions of matter), but other interpretations considered the elements to be divisible into infinitely small pieces without changing their nature. While the classification of the material world in ancient Indian, Hellenistic Egypt, and ancient Greece into Air, Earth, Fire and Water was ...

Vivisection
Vivisection () is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The word is, more broadly, used as a pejorative catch-all term for experimentation on live animalsTansey, E.MReview of ''Vivisection in Historical Perspective by Nicholaas A. Rupke, book reviews, National Center for Biotechnology Information, p. 226. by organizations opposed to animal experimentation,Yarri, Donna''The Ethics of Animal Experimentation: A Critical Analysis and Constructive Christian Proposal, Oxford University Press, 2005, p. 163. but the term is rarely used by practising scientists. Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture. Animal vivisection Research requiring vivisection techniques that cannot be met through other means is often subject to an external ethics review in conception and implementation, and in many jurisdictions use of anesthesia is ...

Choroid Plexus
The choroid plexus, or plica choroidea, is a plexus of cells that arises from the tela choroidea in each of the ventricles of the brain. Regions of the choroid plexus produce and secrete most of the cerebrospinal fluid (CSF) of the central nervous system. The choroid plexus consists of modified ependymal cells surrounding a core of capillaries and loose connective tissue. Multiple cilia on the ependymal cells move to circulate the cerebrospinal fluid. Structure Location There is a choroid plexus in each of the four ventricles. In the lateral ventricles it is found in the body, and continued in an enlarged amount in the atrium. There is no choroid plexus in the anterior horn. In the third ventricle there is a small amount in the roof that is continuous with that in the body, via the interventricular foramina, the channels that connect the lateral ventricles with the third ventricle. A choroid plexus is in part of the roof of the fourth ventricle. Microanatomy The chor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebellum
The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognition, cognitive functions such as attention and language as well as emotion, emotional control such as regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to Motor coordination, coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in Fine motor skill, fine movement, Equilibrioception, equilibrium, Human positions, posture, and motor learning in humans. Anatomica ...

Ventricular System
The ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, allowing for the flow of CSF to circulate. All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium connected by tight junctions that make up the blood–cerebrospinal fluid barrier. Structure The system comprises four ventricles: * lateral ventricles right and left (one for each hemisphere) * third ventricle * fourth ventricle There are several foramina, openings acting as channels, that connect the ventricles. The interventricular foramina (also called the foramina of Monro) connect the lateral ventricles to the third ventricle through which the cerebrospinal fluid can flow. Ventric ...

Library Of Alexandria
The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The Library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts.Murray, S. A., (2009). The library: An illustrated history. New York: Skyhorse Publishing, p.17 The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the Library, but the Library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The Library quickly acquired many papyrus scrolls, owing largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many such scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height. Alexandria came to be regarde ...

Dissection
Dissection (from Latin ' "to cut to pieces"; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine. Consequently, dissection is typically conducted in a morgue or in an anatomy lab. Dissection has been used for centuries to explore anatomy. Objections to the use of cadavers have led to the use of alternatives including virtual dissection of computer models. Overview Plant and animal b ...

Herophilos
Herophilos (; grc-gre, Ἡρόφιλος; 335–280 BC), sometimes Latinised Herophilus, was a Greek physician regarded as one of the earliest anatomists. Born in Chalcedon, he spent the majority of his life in Alexandria. He was the first scientist to systematically perform scientific dissections of human cadavers. He recorded his findings in over nine works, which are now all lost. The early Christian author Tertullian states that Herophilos vivisected at least 600 live prisoners; however, this account has been disputed by many historians.Scarboroug"Celsus on Human Vivisection at Ptolemaic Alexandria" ''Clio Medica. Acta Academiae Internationalis Historiae Medicinae. Vol. 11'', 1976 He is often seen as the father of anatomy. Life Herophilos was born in Chalcedon in Asia Minor (now Kadıköy, Turkey), c. 335 BC. Not much is known about his early life other than he moved to Alexandria at a fairly young age to begin his schooling. As an adult Herophilos was a teacher, and ...

Diagram Showing Where The Ventricles Are In The Brain CRUK 387
A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word ''graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term " illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links. In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, represen ...

Democritus
Democritus (; el, Δημόκριτος, ''Dēmókritos'', meaning "chosen of the people"; – ) was an Ancient Greek pre-Socratic philosopher from Abdera, primarily remembered today for his formulation of an atomic theory of the universe. None of his work has survived. Life Although many anecdotes about Democritus' life survive, their authenticity cannot be verified and modern scholars doubt their accuracy. Democritus was said to be born in the city of Abdera in Thrace, an Ionian colony of Teos,. Ancient accounts of his life have claimed that he lived to a very old age, with some writers claiming that he was over a hundred years old at the time of his death. Philosophy and science states that the relation between Democritus and his predecessor Leucippus is not clear; while earlier ancient sources such as Aristotle and Theophrastus credit Leucippus with the invention of atomism and credit its doctrines to both philosophers, later sources only credit Democritus, making defi ...
