Nerve injuryNerve injury is an injury to nervous tissue. There is no single classification system that can describe all the many variations of nerve injuries. In 1941, Seddon introduced a classification of nerve injuries based on three main types of nerve fiber injury and whether there is continuity of the nerve. Usually, however, peripheral nerve injuries are classified in five stages, based on the extent of damage to both the nerve and the surrounding connective tissue, since supporting glial cells may be involved.
Voltage clampThe voltage clamp is an experimental method used by electrophysiologists to measure the ion currents through the membranes of excitable cells, such as neurons, while holding the membrane voltage at a set level. A basic voltage clamp will iteratively measure the membrane potential, and then change the membrane potential (voltage) to a desired value by adding the necessary current. This "clamps" the cell membrane at a desired constant voltage, allowing the voltage clamp to record what currents are delivered.
SentimentLe sentiment est la composante de l'émotion qui implique les fonctions cognitives de l'organisme, la manière d'apprécier. Le sentiment est à l'origine d'une connaissance immédiate ou d'une simple impression. Il renvoie à la perception de l'état physiologique du moment. Le sens psychologique de sentiment qui comprend un état affectif est à distinguer du sens propre de la sensibilité. thumb|280px|Sensitive (M. Blay, 1910). Le sentiment est un élément très fort dans les modes de pensée, au point qu'il apparaît dominant dans certains raisonnements.
Nerve conduction studyA nerve conduction study (NCS) is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body. These tests may be performed by medical specialists such as clinical neurophysiologists, physical therapists, chiropractors, physiatrists (physical medicine and rehabilitation physicians), and neurologists who subspecialize in electrodiagnostic medicine.
RadiculopathyRadiculopathy, also commonly referred to as pinched nerve, refers to a set of conditions in which one or more nerves are affected and do not work properly (a neuropathy). Radiculopathy can result in pain (radicular pain), weakness, altered sensation (paresthesia) or difficulty controlling specific muscles. Pinched nerves arise when surrounding bone or tissue, such as cartilage, muscles or tendons, put pressure on the nerve and disrupt its function. In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord.
Psychological TypesPsychological Types (Psychologische Typen) is a book by Carl Jung that was originally published in German by Rascher Verlag in 1921, and translated into English in 1923, becoming volume 6 of The Collected Works of C. G. Jung. In the book, Jung proposes four main functions of consciousness: two perceiving or non-rational functions (Sensation and Intuition), and two judging or rational functions (Thinking and Feeling). These functions are modified by two main attitude types: extraversion and introversion.
Myers Briggs Type IndicatorLe Myers Briggs Type Indicator (MBTI) est un outil d'évaluation psychologique déterminant le type psychologique d'un sujet parmi seize types différents, suivant une méthode proposée en 1962 par Isabel Briggs Myers et Katherine Cook Briggs. Il sert comme outil dans les identifications des dominantes psychologiques des personnes dans des cadres liés au management ou aux problèmes dans le cadre des relations interpersonnelles.
Chirurgie de la mainIssue de la chirurgie de l'appareil locomoteur, c'est-à-dire de la chirurgie des os et des articulations, la chirurgie de la main est devenue une spécialité à part entière, car la main est un univers chirurgical qui nécessite des connaissances en orthopédie, en chirurgie plastique, et en micro chirurgie. Comme elle intervient dans toutes les actions humaines, elle est concernée au premier chef par les traumatismes de toutes sortes.
