Catastrophic Injury
A catastrophic injury is a severe injury to the spine, spinal cord, or brain. It may also include skull or spinal fractures. This is a subset of the definition for the legal term ''catastrophic injury'', which is based on the definition used by the American Medical Association. The National Center for Catastrophic Sport Injury Research in the United States classifies catastrophic injuries based on the three outcomes associated with them: fatality, those causing permanent severe functional disability, and those causing severe head or neck trauma with no permanent disability. A fatal injury may be a direct result of trauma sustained during an activity or may occur indirectly. The indirect nonfatal catastrophic injury may occur as a result of systemic failure from exertion during an activity, such as from cardiovascular conditions, heat illness, exertional hyponatremia, or dehydration, or a complication to a nonfatal injury. Indirect fatalities are usually caused by cardiovascular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injury
Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects, by heat or cold, or by venoms and biotoxins. Injury prompts an inflammatory response in many taxa of animals; this prompts wound healing. In both plants and animals, substances are often released to help to occlude the wound, limiting loss of fluids and the entry of pathogens such as bacteria. Many organisms secrete antimicrobial chemicals which limit wound infection; in addition, animals have a variety of immune responses for the same purpose. Both plants and animals have regrowth mechanisms which may result in complete or partial healing over the injury. Cells too can repair damage to a certain degree. Taxonomic range Animals Injury in animals is sometimes defined as mechanical damage to anatomical struct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlanto-occipital Joint
The atlanto-occipital joint (''Articulatio atlantooccipitalis'') is an articulation between the atlas bone and the occipital bone. It consists of a pair of condyloid joints. It is a synovial joint. Structure The atlanto-occipital joint is an articulation between the atlas bone and the occipital bone. It consists of a pair of condyloid joints. It is a synovial joint. Ligaments The ligaments connecting the bones are: * Two articular capsules * Posterior atlanto-occipital membrane * Anterior atlanto-occipital membrane Capsule The capsules of the atlantooccipital articulation surround the condyles of the occipital bone, and connect them with the articular processes of the atlas: they are thin and loose. Variation Atlantooccipital fusion, also known as occipitalization of the atlas, is a congenital or acquired anomaly characterized by the partial or complete fusion of the atlas to the base of the occipital bone. It is found in 0.12% to 0.72% of the population. This fusio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces And Territories Of Canada
Canada has ten provinces and three territories that are sub-national administrative divisions under the jurisdiction of the Constitution of Canada, Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully Independence, independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the List of countries and dependencies by area, world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Acts, British North America Act, 1867''), whereas territories are federal territories whose governments a ...

Spinal Cord Injury
A spinal cord injury (SCI) is damage to the spinal cord that causes temporary or permanent changes in its function. It is a destructive neurological and pathological state that causes major motor, sensory and autonomic dysfunctions. Symptoms of spinal cord injury may include loss of muscle function, sensation, or autonomic function in the parts of the body served by the spinal cord below the level of the injury. Injury can occur at any level of the spinal cord and can be ''complete'', with a total loss of sensation and muscle function at lower sacral segments, or ''incomplete'', meaning some nervous signals are able to travel past the injured area of the cord up to the Sacral S4-5 spinal cord segments. Depending on the location and severity of damage, the symptoms vary, from numbness to paralysis, including bowel or bladder incontinence. Long term outcomes also range widely, from full recovery to permanent tetraplegia (also called quadriplegia) or paraplegia. Complications c ...

Diving is an internationally recognised sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a recreational pastime. Competitors possess many of the same characteristics as gymnastics, gymnasts and dancers, including strength, flexibility, kinaesthetic judgement and air awareness. Some professional divers were originally gymnasts or dancers as both the sports have similar characteristics to diving. Dmitri Sautin holds the record for most Olympic diving medals won, by winning eight medals in total between 1992 and 2008.

Skiing
Skiing is the use of skis to glide on snow for basic transport, a recreational activity, or a competitive winter sport. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski and Snowboard Federation (FIS). History Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced more than 100 centuries ago in the Altai Mountains, according to an interpretation of ancient paintings. However, this continues to be debated. The word "ski" comes from the Old Norse word "skíð" which means to "split piece of wood or firewood". Asymmetrical skis were used in northern Finland and Sweden until at least the late 19th century. On one foot, the skier wore a long straight non-arching ski for sliding, and a shorter ski was worn on the other foot for kicking. The underside of the short ski was either plain or covered with animal skin to aid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
