Cheek
The cheeks ( la, buccae) constitute the area of the face below the eyes and between the nose and the left or right ear. "Buccal" means relating to the cheek. In humans, the region is innervated by the buccal nerve. The area between the inside of the cheek and the teeth and gums is called the vestibule or buccal pouch or buccal cavity and forms part of the mouth. In other animals the cheeks may also be referred to as jowls. Structure Humans Cheeks are fleshy in humans, the skin being suspended by the chin and the jaws, and forming the lateral wall of the human mouth, visibly touching the cheekbone below the eye. The inside of the cheek is lined with a mucous membrane (buccal mucosa, part of the oral mucosa). During mastication (chewing), the cheeks and tongue between them serve to keep the food between the teeth. Other animals The cheeks are covered externally by hairy skin, and internally by stratified squamous epithelium. This is mostly smooth, but may have caudally dir ...

Mesoamerica
Mesoamerica is a historical region and cultural area in southern North America and most of Central America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. Within this region pre-Columbian societies flourished for more than 3,000 years before the Spanish colonization of the Americas. Mesoamerica was the site of two of the most profound historical transformations in world history: primary urban generation, and the formation of New World cultures out of the long encounters among indigenous, European, African and Asian cultures. In the 16th century, Eurasian diseases such as smallpox and measles, which were endemic among the colonists but new to North America, caused the deaths of upwards of 90% of the indigenous people, resulting in great losses to their societies and cultures. Mesoamerica is one of the five areas in the world where ancient civilization arose independently (see cradle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aztec
The Aztecs () were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states ('' altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, city-state of the Mexica or Tenochca; Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahua polities or peoples of central Mexico in the prehispanic era, as well as the Spanish colonial era (1521–1821). The definitions of Aztec and Aztecs ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zapotec Civilization
The Zapotec civilization ( "The People"; 700 BC–1521 AD) was an indigenous pre-Columbian civilization that flourished in the Valley of Oaxaca in Mesoamerica. Archaeological evidence shows that their culture originated at least 2,500 years ago. The Zapotec archaeological site at the ancient city of Monte Albán has monumental buildings, ball courts, magnificent tombs and grave goods, including finely worked gold jewelry. Monte Albán was one of the first major cities in Mesoamerica. It was the center of a Zapotec state that dominated much of the territory which today is known as the Mexican state of Oaxaca. History Zapotec civilization originated in the Central Valleys of Oaxaca in the late 6th century BC. The three valleys were divided among three different-sized societies, separated by “no-man’s-land” in the middle. The city of Oaxaca much later developed in that area. Archaeological evidence, such as burned temples and sacrificed war captives, suggests that t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epi-Olmec Culture
The Epi-Olmec culture was a cultural area in the central region of the present-day Mexican state of Veracruz. Concentrated in the Papaloapan River basin, a culture that existed during the Late Formative period, from roughly 300 BCE to roughly 250 CE. Epi-Olmec was a successor culture to the Olmec, hence the prefix "epi-" or "post-". Although Epi-Olmec did not attain the far-reaching achievements of that earlier culture, it did realize, with its sophisticated calendrics and writing system, a level of cultural complexity unknown to the Olmecs. Tres Zapotes and eventually Cerro de las Mesas were the largest Epi-Olmec centers though neither would reach the size and importance of the great Olmec cities before them nor El Tajín after them. Other Epi-Olmec sites of note include El Mesón, Lerdo de Tejada, La Mojarra, Bezuapan, and Chuniapan de Abajo. Cultural context The rise of the Epi-Olmec culture on the western edge of the Olmec heartland coincides with the depopulation of ...
