  • The Human Body is a 7-part BBC documentary series first shown on 20 May 1998, BBC1. Presented by Robert Winston, a medical scientist and leading commentator on medical matters, The Human Body takes the viewer into one of the most alien worlds imaginable.
  • alternative names for the body of a human being; “Leonardo studied the human body”; “he has a strong physique”; “the spirit is willing but the flesh is weak”
  • The human body is the entire structure of a human organism, and consists of a head, neck, torso, two arms and two legs. By the time the human reaches adulthood, the body consists of close to 50 trillion cells, the basic unit of life.


  • Of considerable or relatively great size, extent, or capacity
  • Of greater size than the ordinary, esp. with reference to a size of clothing or to the size of a packaged commodity
  • Jupiter is not only the most massive planet in the solar system, but it may be one of the most influential as well. in LARGEST, NASA takes a close look at Jupiter, and considers its scientific and poetic place in the solar system.
  • Pursuing an occupation or commercial activity on a significant scale


  • A secreting cell or group of cells on or within a plant structure
  • A gland is an organ in an animal’s body that synthesizes a substance for release such as hormones or breast milk, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland).
  • any of various organs that synthesize substances needed by the body and release it through ducts or directly into the bloodstream
  • An organ in the human or animal body that secretes particular chemical substances for use in the body or for discharge into the surroundings
  • A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid. The most common example is in the head of a tap (faucet) where the gland is usually packed with string which has been soaked in tallow or similar grease.
  • A structure resembling this, esp. a lymph node

Le Jour ni l'Heure P7260003 : buste, 1910, d'Olof (Olaus) Rudbeck, 1630-1702, auteur de l'"Alantica sive Manhem", par Carl Eldh, 1873-1954, Uppsala, Uppland, Suède, lundi 26 juillet 2010, 13:59:21
Olof Rudbeck, Sr. (1630-1702), is one of Uppsala University’s most outstanding figures throughout the centuries. He was the son of a bishop from Västerås and entered the University at a tender age. Medical education was not especially advanced at Uppsala at the time, but the young Rudbeck made what has been called ‘the first scientific discovery by a Swede,’ the lymphatic gland and its diffusion in the human body.

A Danish scientist had made roughly the same discoveries at the same time, and the two gentlemen naturally wound up at odds with each other about which one of them had been first. At any rate, Rudbeck had performed a scientific feat and as a young man made a name for himself among the learned in Europe.

After a period abroad Rudbeck returned to Uppsala, and in 1660 he was appointed to one of the chairs at the Faculty of Medicine (at that time there were only two). He held the post until 1692, when he was succeeded by his son, Olof Rudbeck, Jr. On several occasions he was rector magnificus of the University.

As an expression of his ambitions in medicine, in the early 1660s he had a Theatrum anatomicum built, for dissections of human cadavers. It is easy to imagine what a bold move this was, to build something so large right on top of the university’s main building, that is, the Gustavianum. This cupola with its sundial still today lends the building its special character.

Otherwise Rudbeck became best known for his book Atlantica, an extremely patriotic account of ancient history, today largely regarded as learned fantasies. But many other aspects of Rudbeck’s work have been of lasting value. Together with the Chancellor, Magnus Gabriel De la Gardie, he introduced the so-called ‘exercitia.’ They meant that young students from the nobility received training in useful pursuits such as riding, dancing, fencing, modern languages, etc. The riding academy that Rudbeck had built stood where University Hall now stands, and academic training in riding is still provided. He also arranged to have a botanical garden established (the present-day Linnæan Garden), set up boat connections with Stockholm, built bridges and aqueducts, etc. He was also a composer and had a fantastic singing voice, and he sometimes performed in the cathedral.

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms.
Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel. Unlike insects, spiders do not have antennae. In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure.
Their abdomens bear appendages that have been modified into spinnerets that extrude silk from up to six types of silk glands within their abdomen. Spider webs vary widely in size, shape and the amount of sticky thread used. It now appears that the spiral orb web may be one of the earliest forms, and spiders that produce tangled cobwebs are more abundant and diverse than orb-web spiders.
Spiders’ guts are too narrow to take solids, and they liquidize their food by flooding it with digestive enzymes and grinding it with the bases of their pedipalps, as they do not have true jaws.
Male spiders identify themselves by a variety of complex courtship rituals to avoid being eaten by the females. Males of most species survive a few matings, limited mainly by their short life spans.
Although most spiders live for at most two years, tarantulas and other mygalomorph spiders can live up to 25 years in captivity.
While the venom of a few species is dangerous to humans.scientists are now researching the use of spider venom in medicine and as non-polluting pesticides. Spider silk provides a combination of lightness, strength and elasticity that is superior to that of synthetic materials, and spider silk genes have been inserted into mammals and plants to see if these can be used as silk factories. As a result of their wide range of behaviors, spiders have become common symbols in art and mythology symbolizing various combinations of patience, cruelty and creative powers.
