Quadrant (abdomen)

The human abdomen is divided into regions by anatomists and physicians for purposes of study, diagnosis, and therapy. In the four-region scheme, four quadrants allow localisation of pain and tenderness, scars, lumps, and other items of interest, narrowing in on which organs and tissues may be involved. The quadrants are referred to as the left lower quadrant, left upper quadrant, right upper quadrant and right lower quadrant, as follows.

The left lower quadrant (LLQ) of the human abdomen is the area left of the midline and below the umbilicus. The LLQ includes the left iliac fossa and half of the left flank region.

The term is not used in comparative anatomy, since most other animals do not stand erect. The equivalent term for animals is left posterior quadrant.

The left upper quadrant (LUQ) extends from the median plane to the left of the patient, and from the umbilical plane to the left ribcage.

The equivalent term for animals is 'left anterior quadrant'.

The right upper quadrant (RUQ) extends from the median plane to the right of the patient, and from the umbilical plane to the right ribcage.

Quadrant (plane geometry)

The axes of a two-dimensional Cartesian system divide the plane into four infinite regions, called quadrants, each bounded by two half-axes.

These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the two coordinates are (+,+)), II (−,+), III (−,−), and IV (+,−). When the axes are drawn according to the mathematical custom, the numbering goes counter-clockwise starting from the upper right ("northeast") quadrant.

Quadrant Cycle Company

The Quadrant Cycle Company was a company in Birmingham, England that was established in 1890 as a bicycle manufacturer. They advanced to make motorcycles from 1899 until their demise in 1928. They also made a tricar called Carette in 1899 and a small number of cars for about two years around 1906.

The company exhibited a car chassis with a four-speed Lloyd gearbox of the style known as "crossed rollers"; this allowed direct drive at all speeds. The used 14/16 or 20/22 hp engines made by White and Poppe.

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.

Anatomy (film)

Anatomy (German: Anatomie) is a 2000 German horror film written and directed by Stefan Ruzowitzky that stars Franka Potente. A sequel, Anatomy 2 (Anatomie 2) was released in 2003. The film enjoyed a huge box office success in Germany, and Columbia Pictures released the film's English-dubbed version in the United States theatrically.

Synopsis

Medical student Paula Henning (Franka Potente) wins a place in a summer course at the prestigious University of Heidelberg Medical School. Her grandfather had a great name there before retiring, including being the discoverer of a useful drug, Promidal. They are tutored by Professor Grombek, who announces the hard work ahead. He also tells them that he will be using the elimination system, where the six lower grades will be periodically discarded. During one of their courses on anatomy, the body of David, a young man that Paula met and helped on the train trip, turns up on her dissection table. She is then humiliated by Professor Grombek, who dares her to cut and dissect the heart. She remarks that the body presents strange cuts, but this is dismissed as bad handling by the morgue caretaker. She decides to investigate the mysterious circumstances surrounding his death. When she goes to cut a sample for an independent test she is amazed to find a triple "A" mark near David's ankle. She is then startled by the medical school's mortuary preparetor, who wants to know if Professor Grombek is aware of her acts.
