Grey's Anatomy

Grey's Anatomy is an American medical drama television series that premiered on American Broadcasting Company (ABC) as a mid-season replacement on March 27, 2005, and is currently in its 12th season. The series focuses on the fictional lives of surgical interns and residents as they gradually evolve into seasoned doctors, while trying to maintain personal lives and relationships. The title is a play on the name Gray's Anatomy, an English-language human anatomy textbook originally written by Henry Gray. The show's premise originated with Shonda Rhimes, who serves as an executive producer, along with Betsy Beers, Mark Gordon, Krista Vernoff, Rob Corn, Mark Wilding, and Allan Heinberg. The series was created to be racially diverse, utilizing a color-blind casting technique. While the show is set in Seattle, it is primarily filmed in Los Angeles, California.

The series' protagonist is Dr. Meredith Grey (Ellen Pompeo), who originally is accepted into the residency program at the fictional Seattle Grace Hospital. Meredith is assigned to work under Dr. Miranda Bailey (Chandra Wilson), along with Dr. Cristina Yang (Sandra Oh), Dr. George O'Malley (T. R. Knight), Dr. Izzie Stevens (Katherine Heigl), and Dr. Alex Karev (Justin Chambers). Following O'Malley's death and Stevens' departure, the hospital's merger with Mercy West brings in Dr. Jackson Avery (Jesse Williams) and Dr. April Kepner (Sarah Drew), in the sixth season.

Grey alien

Grey aliens, also referred to as "Alien Greys", "Greys", "Grays", "Roswell Greys", and "Zeta Reticulans", are alleged extraterrestrial beings whose existence is promoted in ufological, paranormal, and New Age communities, and who are named for their unique skin color. Forty-three percent of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect including their nature (ETs, extradimensionals, demons, or machines), origins, moral dispositions, intentions, and physical appearances (even varying in their eponymous skin color). A composite description derived from overlap in claims would have Greys as small-bodied sexless beings with smooth grey-colored skin, enlarged head and large black eyes.

The origin of the idea of the Grey is commonly associated with the Betty and Barney Hill abduction claim which took place in 1961, although skeptics see precursors in science fiction and earlier paranormal claims. The Grey aliens are also famous from earlier depictions of the Roswell UFO incident from 1947.

In Europe and the United States, surveys show that grey is the color most commonly associated with neutrality, conformity, boredom, uncertainty, old age, indifference, and modesty. Only one percent of respondents chose it as their favorite color.

Etymology

Grey comes from the Middle English grai or grei, from the Anglo-Saxon graeg, and is related to the German grau. The first recorded use of grey as a color name in the English language was in AD 700.

Anatomy

Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. In some of its facets, anatomy is related to embryology and comparative anatomy, which itself is closely related to evolutionary biology and phylogeny.Human anatomy is one of the basic essential sciences of medicine.

The discipline of anatomy is divided into macroscopic and microscopic anatomy. Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells.

The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcasses and cadavers (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging.
