Bird Penis
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation, and through which male placental mammals and marsupials also urinate. The term ''penis'' applies to many intromittent organs of vertebrates and invertebrates, but not to all. As an example, the intromittent organ of most Cephalopoda is the hectocotylus, a specialized arm, and male spiders use their pedipalps. Even within the Vertebrata, there are morphological variants with specific terminology, such as hemipenes. Etymology The word "penis" is taken from the Latin word for "tail". Some derive that from Indo-European ''*pesnis'', and the Greek word πέος = "penis" from Indo-European ''*pesos''. Prior to the adoption of the Latin word in English, the penis was referred to as a "yard". The Oxford English Dictionary cites an example of the word ''yard'' used in this sense from 1379, and notes that in his ''Physical Dictionary'' of 1684, Steven Blanka ...

Asian Elephant
The Asian elephant (''Elephas maximus''), also known as the Asiatic elephant, is the only living ''Elephas'' species. It is the largest living land animal in Asia and the second largest living Elephantidae, elephantid in the world. It is characterised by its long Elephant trunk, trunk with a single finger-like processing; large tusks in males; laterally folded large ears and wrinkled grey skin that is partly depigmented on the trunk, ears or neck. Adult males average in weight and females . It has a large and well developed neocortex of the brain, is highly intelligent and self-aware being able to display behaviours associated with grief, learning and greeting. Three subspecies are recognised—''Sri Lankan elephant, E. m. maximus'', Indian elephant, ''E. m. indicus'' and ''Sumatran elephant, E. m. sumatranus''. The Asian elephant is distributed in the Indian subcontinent and Southeast Asia, from India in the west to Borneo in the east, and Nepal in the north to Sumatra in th ...

Vertebrata
Vertebrates () are animals with a vertebral column (backbone or spine), and a cranium, or skull. The vertebral column surrounds and protects the spinal cord, while the cranium protects the brain. The vertebrates make up the subphylum Vertebrata with some 65,000 species, by far the largest ranked grouping in the phylum Chordata. The vertebrates include mammals, birds, amphibians, and various classes of fish and reptiles. The fish include the jawless Agnatha, and the jawed Gnathostomata. The jawed fish include both the cartilaginous fish and the bony fish. Bony fish include the lobe-finned fish, which gave rise to the tetrapods, the animals with four limbs. Despite their success, vertebrates still only make up less than five percent of all described animal species. The first vertebrates appeared in the Cambrian explosion some 518 million years ago. Jawed vertebrates evolved in the Ordovician, followed by bony fishes in the Devonian. The first amphibians appeared on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek (, ; , ) is an Indo-European languages, Indo-European language, constituting an independent Hellenic languages, Hellenic branch within the Indo-European language family. It is native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the list of languages by first written accounts, longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts ...

Phallus
A phallus (: phalli or phalluses) is a penis (especially when erect), an object that resembles a penis, or a mimetic image of an erect penis. In art history, a figure with an erect penis is described as ''ithyphallic''. Any object that symbolically—or, more precisely, iconically—resembles a penis may also be referred to as a phallus; however, such objects are more often referred to as being phallic (as in "phallic symbol"). Such symbols often represent fertility and cultural implications that are associated with the male sexual organ, as well as the male orgasm. Etymology The term is a loanword from Latin ''phallus'', itself borrowed from Greek (''phallos''), which is ultimately a derivation from the Proto-Indo-European root *''bʰel''- "to inflate, swell". Compare with Old Norse (and modern Icelandic) ''boli'', "bull", Old English ''bulluc'', "bullock", Greek , "whale". Archaeology The Hohle phallus, a 28,000-year-old siltstone phallus discovered in the Hohle Fels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euphemism
A euphemism ( ) is when an expression that could offend or imply something unpleasant is replaced with one that is agreeable or inoffensive.

Slang
A slang is a vocabulary (words, phrases, and linguistic usages) of an informal register, common in everyday conversation but avoided in formal writing and speech. It also often refers to the language exclusively used by the members of particular in-groups in order to establish group identity, exclude outsiders, or both. The word itself came about in the 18th century and has been defined in multiple ways since its conception, with no single technical usage in linguistics. Etymology of the word ''slang'' In its earliest attested use (1756), the word ''slang'' referred to the vocabulary of "low" or "disreputable" people. By the early nineteenth century, it was no longer exclusively associated with disreputable people, but continued to be applied to usages below the level of standard educated speech. In Scots dialect it meant "talk, chat, gossip", as used by Aberdeen poet William Scott in 1832: "The slang gaed on aboot their war'ly care." In northern English dialect it me ...

Excretory
Excretion is elimination of metabolic waste, which is an essential process in all organisms. In vertebrates, this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. For example, placental mammals expel urine from the bladder through the urethra, which is part of the excretory system. Unicellular organisms discharge waste products directly through the surface of the cell. During life activities such as cellular respiration, several chemical reactions take place in the body. These are known as metabolism. These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion. Processes across various types of life Plants Green pl ...

Steven Blankaart
Steven Blankaart Latinized as Stephanus Blancardus (24 October 1650, Middelburg, Zeeland, Middelburg – 23 February 1704, Amsterdam) was a Dutch physician, iatrochemist, and Entomology, entomologist, who worked on the same field as Jan Swammerdam. Blankaart proved the existence of a capillary system, as had been suggested by Leonardo da Vinci, by spouting up blood vessels, though he failed to realize the true significance of his findings. He is known for his development of injection techniques for this study and for writing the first Dutch book on child medicine. Blankaart translated works of John Mayow. Life Blankaart was the son of Nicolaas Blankaart, a professor in Greek and History in Steinfurt (1645–1650) and Middelburg, Zeeland, Middelburg (1650–1666), who moved to Heerenveen to become the physician of Countess Albertine Agnes of Nassau; he was appointed in Franeker in 1669.

Proto-Indo-European Language
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age. The majority of linguistic work during the 19th century was devoted to the reconstruction of PIE and its daughter languages, and many of the modern techniques of linguistic reconstruction (such as the comparative method) were developed as a result. PIE is hypothesized to have been spoken as a single language from approximately 4500 BCE to 2500 BCE during the Late Neolithic to Early Bronze Age, though estimates vary by more than a thousand years. According to the prevailing Kurgan hypothesis, the original homeland of the Proto-Indo-Europeans may have been in the Pon ...
