Keel (bird anatomy)

A keel or carina (plural carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight. Keels do not exist on all birds; in particular, some flightless birds lack a keel structure.

Historically, the presence or absence of a pronounced keel structure was used as a broad classification of birds into two orders: Carinatae (from carina, "keel"), having a pronounced keel; and ratites (from ratis, "raft" — referring to the flatness of the sternum), having a subtle keel structure or lacking one entirely. However, this classification has fallen into disuse as evolutionary studies have shown that many flightless birds have evolved from flighted birds. The current definition of Carinatae now includes all extant birds.

Anatomy 2

Anatomy 2 (German: Anatomie 2) is a 2003 German thriller film written and directed by Stefan Ruzowitzky. It's the sequel to the 2000 film Anatomy, that starred Franka Potente. The story moves to Berlin for this film.

Plot

The Heidelberg chapter of the Anti-Hippocratic Society for unrestricted medical research has been shut down, but at a prestigious Berlin hospital the society still thrives. The young neurosurgeon Jo from Duisburg gets caught up in a research group led by doctor Mueller LaRousse, who urges his students to test their progress on themselves. Jo participates in the trials to eventually help his brother, who has Muscular Dystrophy. When Jo and some of his fellow students show some reluctance, Mueller LaRousse uses alternative means to punish them before they can give up the society to Paula Henning, who is now investigating the society for the police.

Cast

Bird

Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.

The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.

The finger

In Western culture, the finger or the middle finger (as in giving someone the (middle) finger or the bird or flipping someone off,) is an obscene hand gesture. It communicates moderate to extreme contempt, and is roughly equivalent in meaning to "fuck off", "fuck you", "shove it up your ass", "up yours" or "go fuck yourself". It is performed by showing the back of a closed fist that has only the middle finger extended upwards, though in some locales the thumb is extended. Extending the finger is considered a symbol of contempt in several cultures, especially Western ones. Many cultures use similar gestures to display their disrespect, although others use it to express pointing without intentional disrespect toward other cultures.

The gesture dates back to Ancient Greece and it was also used in Ancient Rome. Historically, it represented the phallus. In some modern cultures, it has gained increasing recognition as a sign of disrespect, and has been used by music artists (notably more common among hardcore punk bands and rappers), actors, celebrities, athletes, and politicians. Most still view the gesture as obscene. The index finger and ring finger besides the middle finger in more contemporary periods has been likened to represent the testicles.
