Human Tooth Sharpening
Human tooth sharpening is the practice of manually sharpening the teeth, usually the front incisors. Filed teeth are customary in various cultures. Many remojadas figurines found in part of Mexico have filed teeth and it is believed to have been common practice in their culture. The Zappo Zap people of the Democratic Republic of Congo are believed to have filed their teeth. Historically it was done for spiritual purposes, with some exceptions, but in modern times it is usually aesthetic in nature as an form of body modification. History Many cultures have practiced this form of body modification. In Bali, in a ritual known as Potong gigi or cut teeth, teenagers have their canine teeth filed down because it is thought they represented negative emotions such as anger and jealousy. It is also seen as a way to spiritually separate them from their animalistic instincts and ancestors. After this tradition is completed the teens are now considered adults and are allowed to have se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Herero People
The Herero ( hz, Ovaherero) are a Bantu ethnic group inhabiting parts of Southern Africa. There were an estimated 250,000 Herero people in Namibia in 2013. They speak Otjiherero, a Bantu language. Though the Herero primarily reside in Namibia, there are also significant populations in Botswana and Angola. In Botswana, the Hereros or Ovaherero are mostly found in Maun and some villages surrounding Maun. These villages among others are Sepopa, Toromuja, Karee and Etsha. Some of them are at Mahalapye. In the South eastern part of Botswana they are at Pilane. There are also a few of them in the Kgalagadi South, that is Tsabong, Omawaneni, Draaihoek and Makopong Villages.

Chisel
A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it. Chiselling use involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight (' trip hammer') may be used to drive a chisel into the material. A gouge (one type of chisel) serves to carve small pieces from the material, particularly in woodworking, woodturning and sculpture. Gouges most frequently produce concave surfaces. A gouge typically has a 'U'-shaped cross-section. Etymology ''Chisel'' comes from the Old French ''cisel'', modern ''ciseau'', Late Latin ' ...

Mentawai People
Mentawai (also known as Mentawei and Mentawi) people are the native people of the Mentawai Islands (principally Siberut, Sipura, North Pagai and South Pagai) about 100 miles from West Sumatra province, Indonesia. They live a semi-nomadic hunter-gatherer lifestyle in the coastal and rainforest environments of the islands and are also one of the oldest tribes in Indonesia. The Mentawai population is estimated to be about 64,000. The Mentawai tribe is documented to have migrated from Nias – a northern island – to the Mentawai islands, living in an isolated life for centuries until they encountered the Dutch in 1621. The ancestors of the indigenous Mentawai people are believed to have first migrated to the region somewhere between 2000 to 500 BCE. The Mentawai language belongs to the Austronesian language family. They follow their own animist belief system called Arat Sabulungan, that links the supernatural powers of ancestral spirits to the ecology of the rainforest. When th ...

Mandibular Arch
The pharyngeal arches, also known as visceral arches'','' are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches. In the human embryo, the arches are first seen during the fourth week of development. They appear as a series of outpouchings of mesoderm on both sides of the developing pharynx. The vasculature of the pharyngeal arches is known as the aortic arches. In fish, the branchial arches support the gills. Structure In vertebrates, the pharyngeal arches are derived from all three germ layers (the primary layers of cells that form during embryogenesis). Neural crest cells enter these arches where they contribute to features of the skull and facial skeleton such as bone and cartilage. However, the existence of pharyngeal structures before neural crest cells evolved is indicated by the existence of neural crest-independent mechanisms of pharynge ...

Maxillary Central Incisor
The maxillary central incisor is a human tooth in the front upper jaw, or maxilla, and is usually the most visible of all teeth in the mouth. It is located mesial (closer to the midline of the face) to the maxillary lateral incisor. As with all incisors, their function is for shearing or cutting food during mastication (chewing). There is typically a single cusp on each tooth, called an incisal ridge or incisal edge. Formation of these teeth begins at 14 weeks in utero for the deciduous (baby) set and 3–4 months of age for the permanent set. There are some minor differences between the deciduous maxillary central incisor and that of the permanent maxillary central incisor. The deciduous tooth appears in the mouth at 8–12 months of age and shed at 6–7 years, and is replaced by the permanent tooth around 7–8 years of age. The permanent tooth is larger and is longer than it is wide. The maxillary central incisors contact each other at the midline of the face. The ma ...

Maxilla
The maxilla (plural: ''maxillae'' ) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw. Structure In humans, the maxilla consists of: * The body of the maxilla * Four processes ** the zygomatic process ** the frontal process of maxilla ** the alveolar process ** the palatine process * three surfaces – anterior, posterior, medial * the Infraorbital foramen * the maxillary sinus * the incisive foramen Articulations Each maxilla articulates with nine bones: * two of the cranium: the frontal and ethmoid * seven of the face: the nasal, zygomatic, lacrimal ...

Upoto
Upoto was a village on the right bank of the Congo River, now a district of Lisala in the Mongala province of the Democratic Republic of the Congo.

Anterior Teeth
In dentistry, the term anterior teeth usually refers as a group to the incisors and canine teeth as distinguished from the posterior teeth, which are the premolars and molars. The distinction is one of anterior (front of the body) versus posterior (rear of the body). The distinction holds in both the upper jaw (maxilla) and lower jaw (mandible In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone ...). As a rough guide, it can be said that the anterior teeth are tailored to biting (breaking the food into chewable chunks) whereas the posterior teeth are tailored to chewing ( comminuting the food into swallowable particles). Anterior teeth are inherently more accessible than are posterior teeth. Sometimes dental health and choice of dental treatment are influenced by this factor. Refe ...

History Of China
The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty (c. 1600–1046 BC), during the reign of king Wu Ding. Ancient historical texts such as the ''Book of Documents'' (early chapters, 11th century BC), the ''Bamboo Annals'' (c. 296 BC) and the ''Records of the Grand Historian'' (c. 91 BC) describe a Xia dynasty before the Shang, but no writing is known from the period, and Oracle Bone script, Shang writings do not indicate the existence of the Xia. The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze, Yangtze River. These Yellow river civilization, Yellow River and Yangtze civilizations arose millennia before the Shang. With thousands of years of continuous history, China is among the world's oldest civilizations and is regarded as one of the Cradle of ...
