Carl-Herman Hjortsjö
Carl-Herman Hjortsjö (8 December 1914 – 3 July 1978), born Carl-Herman Hirschlaff, was a Swedish anatomist, physician, and physical anthropologist. His contributions to historical osteology were instrumental in establishing it as an academic field in Sweden. Hjortsjö was born in Malmö, Sweden, to Herold Hirschlaff, a practicing physician, and Ester Hirschlaff (née Sandstedt). He obtained his medical license in Lund, Sweden, in 1942. During his studies at Lund University's Department of Anatomy, Hjortsjö was taught by and Carl Magnus Fürst, two of Sweden's pioneering anatomists at the time. In 1945, Hjortsjö earned his Doctor of Medicine degree with a dissertation on the morphogenesis of epithelial pulmonary primordium—the development of the early lung tissue—in cats. In 1948, Hjortsjö made significant contributions to the study of human liver anatomy, becoming the first to demonstrate its segmental division. His findings later proved essential for advancements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Human Liver
The liver is a major metabolic organ exclusively found in vertebrates, which performs many essential biological functions such as detoxification of the organism, and the synthesis of various proteins and various other biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm and mostly shielded by the lower right rib cage. Its other metabolic roles include carbohydrate metabolism, the production of a number of hormones, conversion and storage of nutrients such as glucose and glycogen, and the decomposition of red blood cells. Anatomical and medical terminology often use the prefix ''hepat-'' from ἡπατο-, from the Greek word for liver, such as hepatology, and hepatitis The liver is also an accessory digestive organ that produces bile, an alkaline fluid containing cholesterol and bile acids, which emulsifies and aids the breakdown of dietary fat. The gallbladder, a small hollow pouch t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1914 Births
This year saw the beginning of what became known as the First World War, after Archduke Franz Ferdinand of Austria, heir to the Austrian throne was Assassination of Archduke Franz Ferdinand, assassinated by Serbian nationalist Gavrilo Princip. It also saw the first airline to provide scheduled regular commercial passenger services with heavier-than-air aircraft, with the St. Petersburg–Tampa Airboat Line. Events January * January 1 – The St. Petersburg–Tampa Airboat Line in the United States starts services between St. Petersburg, Florida, St. Petersburg and Tampa, Florida, becoming the first airline to provide scheduled regular commercial passenger services with heavier-than-air aircraft, with Tony Jannus (the first federally-licensed pilot) conveying passengers in a Benoist XIV flying boat. Abram C. Pheil, mayor of St. Petersburg, is the first airline passenger, and over 3,000 people witness the first departure. * January 11 **The Sakurajima volcano in Japan ...

Facial Action Coding System
The Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978. Ekman, Friesen, and Joseph C. Hager published a significant update to FACS in 2002. Movements of individual facial muscles are encoded by the FACS from slight different instant changes in facial appearance. It has proven useful to psychologists and to animators. Background In 2009, a study was conducted to study spontaneous facial expressions in sighted and blind judo athletes. They discovered that many facial expressions are innate and not visually learned. Method Using the FACS human coders can manually code nearly any anatomically possible facial expression, deconstructing it into the specific "action units" (AU) and their temporal segments that produced the expression. As AUs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paul Ekman
Paul Ekman (born February 15, 1934) is an American psychologist and professor emeritus at the University of California, San Francisco who is a pioneer in the study of emotions and their relation to facial expressions. He was ranked 59th out of the 100 most eminent psychologists of the twentieth century in 2002 by the ''Review of General Psychology''. His empirical and theoretical work helped to restart the study of emotion and non-verbal communication in the field of psychology, and introduced new quantitative frameworks which researchers could use to do so. He also carried out important early work on the physiology of emotions. Biography Childhood Paul Ekman was born in 1934 in Washington, D.C., and grew up in a Jewish family in New Jersey, Washington, Oregon, and California. His father was a pediatrician and his mother was an attorney. His sister, Joyce Steinhart, is a psychoanalytic psychologist who, before her retirement, practiced in New York City. Ekman originally wan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facial Expression
Facial expression is the motion and positioning of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers and are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species. Humans can adopt a facial expression voluntarily or involuntarily, and the neural mechanisms responsible for controlling the expression differ in each case. Voluntary facial expressions are often socially conditioned and follow a cortical route in the brain. Conversely, involuntary facial expressions are believed to be innate and follow a subcortical route in the brain. Facial recognition can be an emotional experience for the brain and the amygdala is highly involved in the recognition process. Beyond the accessory nature of facial expressions in spoken communication between people, they play a significant role in communication ...

Taxonomize
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolutionary relationships among organisms, both liv ...
