  Organ functions
  Definition : Function of an organ in organ systems.
  Organ systems
  The notion of system (or apparatus) relies upon the concept of vital or organic function / organ functions : organ systems are a set of organs with a definite function.
  The enumeration of the principal functions - and consequently of the systems - remained almost the same since Antiquity, but the classification of them has been very various, e.g., compare Aristotle, Bichat, Cuvier.
  The notion of (...)

• signaling theory
  27 January

  |WKP|
  Definition: Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is when organisms with conflicting interests, such as in sexual selection, should be expected to provide honest signals (no presumption being made of conscious intention) rather than cheating. Mathematical models describe how signalling can contribute to an evolutionarily stable strategy. (...)

• noise
  27 January

  Signals
  The formal study of the information content of signals is the field of information theory.
  The information in a signal is usually accompanied by noise.
  The term noise usually means an undesirable random disturbance, but is often extended to include unwanted signals conflicting with the desired signal (such as crosstalk). The prevention of noise is covered in part under the heading of signal integrity. The separation of desired signals from a background is the field of signal (...)

• signal

  WKP
  Definition : A signal as referred to in communication systems , signal processing , and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon ".
  In the physical world, any quantity exhibiting variation in time or variation in space (such as an image) is potentially a signal that might provide information on the status of a physical system, or convey a message between observers, among other possibilities. It can be defined (...)

• parameters
  27 January

  parameter WKP
  Definition: A parameter (from the Ancient Greek παρά, para: "beside", "subsidiary"; and μέτρον, metron: "measure"), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its performance, status, condition, etc.
  In computing, a parameter is defined as "a reference or (...)

• vital functions
  27 January, by admin

  Definition: Vital functions are organ functions necessary to the life of a organism, as the human body or Homo sapiens.
  It can be for examples :
  respiration or oxygenation of tissues
  digestion or nutrients supply
  maintain of vital physiological parameters

• organ system functions
  27 January

  The notion of system (or apparatus) relies upon the concept of vital or organic function: a system is a set of organs with a definite function. This idea was already present in Antiquity (Galen, Aristotle), but the application of the term "system" is more recent.
  For example, the nervous system was named by Monro (1783), but Rufus of Ephesus (c. 90-120), clearly viewed for the first time the brain, spinal cord, and craniospinal nerves as an anatomical unit, although he wrote little about (...)
