Human head in the context of "Oral surgeon"

The Olmec colossal heads are stone representations of human heads sculpted from large basalt boulders. They range in height from 1.17 to 3.4 metres (3.8 to 11.2 ft). The heads date from at least 900 BCE and are a distinctive feature of the Olmec civilization of ancient Mesoamerica. All portray mature individuals with fleshy cheeks, flat noses, and slightly-crossed eyes; their physical characteristics correspond to a type that is still common among the inhabitants of Tabasco and Veracruz. The backs of the monuments are often flat.

The boulders were brought from the Sierra de Los Tuxtlas mountains of Veracruz. Given that the extremely large slabs of stone used in their production were transported more than 150 kilometres (93 mi), requiring a great deal of human effort and resources, it is thought that the monuments represent portraits of powerful individual Olmec rulers. Each of the known examples has a distinctive headdress. The heads were variously arranged in lines or groups at major Olmec centres, but the method and logistics used to transport the stone to these sites remain unclear. The heads all display distinctive headgear and one theory is that these were worn as protective helmets, maybe worn for war or to take part in a ceremonial Mesoamerican ballgame.

The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems.

The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen), genitals, arms, hands, legs, and feet. The internal human body includes organs, teeth, bones, muscle, tendons, ligaments, blood vessels and blood, lymphatic vessels and lymph.

Headhunting is the practice of hunting a human and collecting the severed head after killing the victim. More portable body parts (such as ear, nose, or scalp) can be taken as trophies, instead. Headhunting was practiced in historic times across parts of Europe, East Asia, Oceania, Southeast Asia, South Asia, Mesoamerica, South America, West Africa, and Central Africa.

The headhunting practice has been the subject of intense study within the anthropological community, where scholars try to assess and interpret its social roles, functions, and motivations. Anthropological writings explore themes in headhunting that include mortification of the rival, ritual violence, cosmological balance, the display of manhood, cannibalism, dominance over the body and soul of his enemies in life and afterlife, as a trophy and proof of killing (achievement in hunting), show of greatness, prestige by taking on a rival's spirit and power, and as a means of securing the services of the victim as a slave in the afterlife.

Bowing (also called stooping) is the act of lowering the torso and head as a social gesture in direction to another person or symbol. It is most prominent in Asian cultures but it is also typical of nobility and aristocracy in many European countries. It is also used in religious contexts, as a form of worship or veneration. Sometimes the gesture may be limited to lowering the head such as in Indonesia, and in many cultures several degrees of the lowness of the bow are distinguished and regarded as appropriate for different circumstances. It is especially prominent in Nepal, India, Cambodia, Thailand, Laos, Vietnam, China, Korea, and Japan, where it may be executed standing or kneeling. Some bows are performed equally by two or more people while others are unequal – the person bowed to either does not bow in return or performs a less low bow in response. A nod of the head may be regarded as the minimal form of bow; forms of kneeling, genuflection, or prostration which involves the hands or whole body touching the ground, are the next levels of gesture.

A bust is a sculpted or cast representation of the upper part of the human body, depicting a person's head and neck, and a variable portion of the chest and shoulders. The piece is normally supported by a plinth. The bust is generally a portrait intended to record the appearance of an individual, but may sometimes represent a type. They may be of any medium used for sculpture, such as marble, bronze, terracotta, plaster, wax or wood.

As a format that allows the most distinctive characteristics of an individual to be depicted with much less work, and therefore expense, and occupying far less space than a full-length statue, the bust has been since ancient times a popular style of life-size portrait sculpture.

A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets (e.g., a policeman's helmet in the United Kingdom) without protective function are sometimes worn. Soldiers wear combat helmets, often made from Kevlar or other lightweight synthetic fibers.

The word helmet is derived from helm, an Old English word for a protective head covering.

An occupational injury is bodily damage resulting from working. The most common organs involved are the spine, hands, the head, lungs, eyes, skeleton, and skin. Occupational injuries can result from exposure to occupational hazards (physical, chemical, biological, or psychosocial), such as temperature, noise, insect or animal bites, blood-borne pathogens, aerosols, hazardous chemicals, radiation, and occupational burnout.

While many prevention methods are set in place, injuries may still occur due to poor ergonomics, manual handling of heavy loads, misuse or failure of equipment, exposure to general hazards, and inadequate safety training.

Headgear, headwear, or headdress is any element of clothing which is worn on one's head, including hats, helmets, turbans and many other types. Headgear is worn for many purposes, including protection against the elements, decoration, or for religious or cultural reasons, including social conventions.

Giuseppe Arcimboldo, also spelled Arcimboldi (Italian: [dʒuˈzɛppe artʃimˈbɔldo]; 5 April 1527 – 11 July 1593), was an Italian Mannerist painter best known for creating imaginative portrait heads made entirely of objects such as fruits, vegetables, flowers, fish and books.

These works form a distinct category from his other productions. He was a conventional court painter of portraits for three Holy Roman Emperors in Vienna and Prague; also producing religious subjects and, among other things, a series of coloured drawings of exotic animals in the imperial menagerie. He specialized in grotesque symbolical compositions of fruits, animals, landscapes, or various inanimate objects arranged into human forms.
