122Muscle contraction — See also: Twitch and Tremor Top down view of skeletal muscle Muscle fiber generates tension through the action of actin and myosin cross bridge cycling. While under tension, the muscle may lengthen, shorten, or …
123Tensor contraction — In multilinear algebra, a tensor contraction is an operation on one or more tensors that arises from the natural pairing of a finite dimensional vector space and its dual. In components, it is expressed as a sum of products of scalar components… …
124Length contraction — Length contraction, according to Hendrik Lorentz, is the physical phenomenon of a decrease in length detected by an observer in objects that travel at any non zero velocity relative to that observer. This contraction (more formally called Lorentz …

126Edge contraction — In graph theory, an edge contraction is an operation which removes an edge from a graph while simultaneously merging together the two vertices it previously connected. Edge contraction is a fundamental operation in the theory of graph minors.… …
127Excitation-contraction coupling — Excitation contraction (EC) coupling is a term coined in 1952 to describe the physiological process of converting an electrical stimulus to a mechanical response [1]. This process is fundamental to muscle physiology, whereby the electrical… …
