Penis
A penis (; : penises or penes) is a sex organ through which male and hermaphrodite animals expel semen during copulation (zoology), copulation, and through which male placental mammals and marsupials also Urination, 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 Hemipenis, hemipenes. Etymology The word "penis" is taken from the Latin word for "Latin profanity#Synonyms and metaphors, tail". Some derive that from Proto-Indo-European language, 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 w ...

Tiger Penis
In traditional Chinese medicine, a tiger penis (Vietnamese language, Vietnamese: ''Pín hổ''; ) is said to have important therapeutic properties. However, there is no scientific proof that tiger penis (or any other animal phallus) can be used to treat any medical disorder. The demand for tiger parts exacerbates the endangered status of the tiger by providing a market for poachers. While tiger penis is consumed in parts of China and Southeast Asia, the consumption of tiger penis is often condemned by most global environmentalism, environmental groups. Genuine tiger genitals are unlikely to be found for sale in public markets; what is usually sold is a fraudulent product made from beef cattle.(An example image is provided below) Health The penis of a tiger, when consumed, is said to be a potent aphrodisiac and an effective treatment for erectile dysfunction.

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".

Intromittent Organ
An intromittent organ is any external organ of a male organism that is specialized to deliver sperm during copulation. Intromittent organs are found most often in terrestrial species, as most non-mammalian aquatic species fertilize their eggs externally, although there are exceptions. For many species in the animal kingdom, the male intromittent organ is a hallmark characteristic of internal fertilization. Species with intromittent organs Invertebrates Molluscs Male cephalopods have a specialized arm, the hectocotylus, which is inserted into the female's mantle cavity to deliver a spermatophore during copulation. In some species, the hectocotylus breaks off inside the female's mantle cavity; in others, it can be used repeatedly to copulate with different females. Arachnids In spiders, the intromittent organs are the male pedipalps, even though these are not primarily sexual organs, but serve as indirect mating organs; in the male the pedipalps have hollow, clubbed tips, o ...

Sex Organ
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes, as well as facilitating fertilization and supporting the development and birth of offspring. Sex organs are found in many species of animals and plants, with their features varying depending on the species. Sex organs are typically differentiated into male and female types. In animals (including humans), the male sex organs include the testicles, epididymis, epididymides, and penis; the female sex organs include the clitoris, Ovary, ovaries, oviducts, and vagina. The testicle in the male and the ovary in the female are called the ''primary sex organs''. All other sex-related organs are known as ''secondary sex organs''. The outer parts are known as the genitals or external genitalia, visible at birth in both sexes, while the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semen
Semen, also known as seminal fluid, is a bodily fluid that contains spermatozoon, spermatozoa which is secreted by the male gonads (sexual glands) and other sexual organs of male or hermaphrodite, hermaphroditic animals. In humans and placental mammals, seminal fluid is ejaculation, ejaculated through the penis and contains Proteolytic enzyme, proteolytic and other enzymes as well as fructose, which promote the survival of spermatozoa and provide a medium through which they can move or "swim" from the vagina into the uterus to fertilization, fertilize the female ovum and form a zygote. semen collection, Semen is collected from animals for artificial insemination or cryoconservation of genetic material. Cryoconservation of animal genetic resources is a practice that calls for the collection of semen in efforts for conservation of a particular breed. Physiology Fertilization Depending on the species, spermatozoa can fertilize ova externally or internally. In external fertiliz ...

Latin Profanity
Latin obscenity is the profane, indecent, or impolite vocabulary of Latin, and its uses. Words deemed obscene were described as (obscene, lewd, unfit for public use), or (improper, in poor taste, undignified). Documented obscenities occurred rarely in classical Latin literature, limited to certain types of writing such as epigrams, but they are commonly used in the graffiti written on the walls of Pompeii and Herculaneum. Among the documents of interest in this area is a letter written by Cicero in 45 BC (''ad Fam.'' 9.22) to a friend called Paetus, in which he alludes to a number of obscene words without actually naming them. Apart from graffiti, the writers who used obscene words most were Catullus and Martial in their shorter poems. Another source is the anonymous '' Priapeia'' (see External links below), a collection of 95 epigrams supposedly written to adorn statues of the fertility god Priapus, whose wooden image was customarily set up to protect orchards against thieves ...

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 ...

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the principal historical dictionary of the English language, published by Oxford University Press (OUP), a University of Oxford publishing house. The dictionary, which published its first edition in 1884, traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, and provides ongoing descriptions of English language usage in its variations around the world. In 1857, work first began on the dictionary, though the first edition was not published until 1884. It began to be published in unbound Serial (literature), fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 b ...

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. His son started as an apprentice of an apothecary. In 1674 he moved to Amsterdam after bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford University Press
Oxford University Press (OUP) is the publishing house of the University of Oxford. It is the largest university press in the world. Its first book was printed in Oxford in 1478, with the Press officially granted the legal right to print books by decree in 1586. It is the second-oldest university press after Cambridge University Press, which was founded in 1534. It is a department of the University of Oxford. It is governed by a group of 15 academics, the Delegates of the Press, appointed by the Vice Chancellor, vice-chancellor of the University of Oxford.

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 ...
