Aelius Galenus or Claudius Galenus, often anglicized as Galen or Galen of Pergamon, was a Roman and Greek physician, surgeon, and philosopher. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic.
Physiology is the scientific study of functions and mechanisms in a living system. As a subdiscipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology.
In psychology, temperament broadly refers to consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes.
The Canon of Medicine is an encyclopedia of medicine in five books compiled by Muslim Persian physician-philosopher Avicenna and completed in 1025. It is among the most influential works of its time. It presents an overview of the contemporary medical knowledge of the Islamic world, which had been influenced by earlier traditions including Greco-Roman medicine, Persian medicine, Chinese medicine and Indian medicine. Its translation from Arabic to Latin in 12th century Toledo greatly influenced the development of medieval medicine. It became the standard textbook for teaching in European universities into the early modern period.
Phlegm is mucus produced by the respiratory system, excluding that produced by the throat nasal passages. It often refers to respiratory mucus expelled by coughing, otherwise known as sputum. Phlegm, and mucus as a whole, is in essence a water-based gel consisting of glycoproteins, immunoglobulins, lipids and other substances. Its composition varies depending on climate, genetics, and state of the immune system. Its color can vary from transparent to pale or dark yellow and green, from light to dark brown, and even to dark grey depending on the contents. The body naturally produces about 1 quart of phlegm every day to capture and clear substances in the air and bacteria from the nose and throat.
Humorism, the humoral theory, or humoralism, was a system of medicine detailing a supposed makeup and workings of the human body, adopted by Ancient Greek and Roman physicians and philosophers.
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and reactivity.
In medicine, both ancient and modern, a dyscrasia is any of various disorders. The word has ancient Greek roots meaning "bad mixture". The concept of dyscrasia was developed by the Greek physician Galen, who elaborated a model of health and disease as a structure of elements, qualities, humors, organs, and temperaments. Health was understood in this perspective to be a condition of harmony or balance among these basic components, called eucrasia. Disease was interpreted as the disproportion of bodily fluids or four humours: phlegm, blood, yellow bile, and black bile. The imbalance was called dyscrasia. In modern medicine, the term is still occasionally used in medical context for an unspecified disorder of the blood, such as a plasma cell dyscrasia.
The Keirsey Temperament Sorter (KTS) is a self-assessed personality questionnaire. It was first introduced in the book Please Understand Me. The KTS is closely associated with the Myers–Briggs Type Indicator (MBTI); however, there are significant practical and theoretical differences between the two personality questionnaires and their associated different descriptions.
Dosha is a central term in ayurveda originating from Sanskrit, which can be translated as "that which can cause problems", and which refers to three categories or types of substances that are believed to be present conceptually in a person's body and mind. These Dosha are assigned specific qualities and functions. These qualities and functions are affected by external and internal stimuli received by the body. Beginning with twentieth-century ayurvedic literature, the "three-dosha theory" has described how the quantities and qualities of three fundamental types of substances called wind, bile, and phlegm fluctuate in the body according to the seasons, time of day, process of digestion, and several other factors and thereby determine changing conditions of growth, aging, health, and disease.
David West Keirsey was an American psychologist, a professor emeritus at California State University, Fullerton, and the author of several books. In his most popular publications, Please Understand Me and the revised and expanded second volume Please Understand Me II (1998), he laid out a self-assessed personality questionnaire, known as the Keirsey Temperament Sorter, which links human behavioral patterns to four temperaments and sixteen character types. Both volumes of Please Understand Me contain the questionnaire for type evaluation with detailed portraits and a systematic treatment of descriptions of temperament traits and personality characteristics. With a focus on conflict management and cooperation, Keirsey specialized in family and partnership counseling and the coaching of children and adults.
Complexion in humans is the natural color, texture, and appearance of the skin, especially on the face.
Praxagoras was a figure of medicine in ancient Greece. He was born on the Greek island of Kos in about 340 BC. Both his father, Nicarchus, and his grandfather were physicians. Very little is known of Praxagoras' personal life, and none of his writings have survived.
Ancient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials. The Greek term for medicine was iatrikē. Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical. Specifically, the ancient Greeks believed health was affected by the humors, geographic location, social class, diet, trauma, beliefs, and mindset. Early on the ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods". As trials continued wherein theories were tested against symptoms and results, the pure spiritual beliefs regarding "punishments" and "gifts" were replaced with a foundation based in the physical, i.e., cause and effect.
In psychology, personality type refers to the psychological classification of individuals. In contrast to personality traits, the existence of personality types remains extremely controversial. Types are sometimes said to involve qualitative differences between people, whereas traits might be construed as quantitative differences. According to type theories, for example, introverts and extraverts are two fundamentally different categories of people. According to trait theories, introversion and extraversion are part of a continuous dimension, with many people in the middle.
The two-factor model of personality is a widely used psychological factor analysis measurement of personality, behavior and temperament. It most often consists of a matrix measuring the factor of introversion and extroversion with some form of people versus task orientation.
The Phlegmatics are a power pop band from Houston, Texas. They are distinguished by their songs about video games, sexual angst, ancient history, social ineptitude and other viewpoints of the societal outsider, set to a powerful, melodic and quirky sound. Sara Cress of The Houston Chronicle described The Phlegmatics music as "…a sound that's smarter than blink-182 and less slick than Weezer, but within the same family of rock."
On the Nature of Man is a work in the Hippocratic Corpus. On the Nature of Man is attributed to Polybus, the son in law and disciple of Hippocrates, through a testimony from Aristotle's History of Animals. However, as with the many other works of the Hippocratic Corpus, the authorship is regarded as dubious in origin.
Iranian traditional medicine (ITM), also known as Persian traditional medicine, is one of the most ancient forms of traditional medicine.
Modern understanding of disease is very different from the way it was understood in ancient Greece and Rome. The way modern physicians approach healing of the sick differs greatly from the methods used by early general healers or elite physicians like Hippocrates or Galen. In modern medicine, the understanding of disease stems from the "germ theory of disease", a concept that emerged in the second half of the 19th century, such that a disease is the result of an invasion of a micro-organism into a living host. Therefore, when a person becomes ill, modern treatments "target" the specific pathogen or bacterium in order to "beat" or "kill" the disease.
