Vermiform Appendix
The appendix (: appendices or appendixes; also vermiform appendix; cecal (or caecal, cæcal) appendix; vermix; or vermiform process) is a finger-like, blind-ended tube connected to the cecum, from which it develops in the embryo. The cecum is a pouch-like structure of the large intestine, located at the junction of the small and the large intestines. The term " vermiform" comes from Latin and means "worm-shaped". The appendix was once considered a vestigial organ, but this view has changed since the early 2000s. Research suggests that the appendix may serve as a reservoir for beneficial gut bacteria. Structure The human appendix averages in length, ranging from . The diameter of the appendix is , and more than is considered a thickened or inflamed appendix. The longest appendix ever removed was long. The appendix is usually located in the lower right quadrant of the abdomen, near the right hip bone. The base of the appendix is located beneath the ileocecal valve tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Francisco Serrão
Francisco Serrão (died 1521) was a Portuguese explorer and a possible cousin of Ferdinand Magellan. His 1512 voyage was the first known European sailing east past Malacca through modern Indonesia and the East Indies. He became a confidant of Sultan Bayan Sirrullah, the ruler of Ternate, becoming his personal advisor. He remained in Ternate where he died around the same time Magellan died. Voyage to the Indies Serrão served as captain of one of three vessels (and second in overall command under António de Abreu) sent from Malacca by Afonso de Albuquerque to find the Spice Islands of Banda in Maluku in 1511. Banda was the world's only source of nutmeg and mace, spices used as flavourings, medicines and preserving agents that were at the time highly valued in European markets. The Portuguese sought to dominate the source, rather than relying on Arab traders who sold it to the Venetians for exorbitant prices. Malay pilots guided the expedition east via Java and along the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jorge Álvares
Jorge Álvares (died 8 July 1521) was a Portuguese explorer. He is credited as the first European to have reached China by sea during the Age of Discovery. His starting of settlements on an island in what is now Hong Kong is still considered a significant achievement, "for establishing commercial agreements with the Chinese nd formaintaining the peace". Exploration In May 1513, Álvares sailed under the Portuguese Malacca captain Rui de Brito Patalim in a junk from Pegu. The expedition was accompanied by five other junks. Álvares himself was accompanied by two other Portuguese mariners.Porter, Jonathan. 996(1996). Macau, the Imaginary City: Culture and Society, 1557 to the Present. Westview Press. Álvares made first contact on Chinese soil on an island near the historic city of Guangzhou in southern China in May 1513. The location of the island, which the Portuguese called Tamão, is not exactly known except that it is in the Pearl River Delta, and scholarship has suggested ...

List Of Explorers
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...
