Webb26 nov. 2024 · Altogether, the fibers and the motor neuron make up the motor unit. Since each bundle contains only one type of fiber, a bundle of slow-twitch fibers and a bundle of fast-twitch fibers will receive information from the brain via separate motor units. If one motor neuron is activated, a weak muscle contraction occurs. Broadly there are two types of muscle fiber: Type I, which is slow, and Type II which are fast. Type II has two divisions of type IIA (oxidative), and type IIX (glycolytic), giving three main fiber types. These fibers have relatively distinct metabolic, contractile, and motor unit properties. The table below differentiates these types of properties. These types of properties—while they are partly dependent on the properties of individual fibers—tend to be relevant and measured at the level o… lithography in electronicsWebb24 aug. 2024 · Your Type I fibers are slow-twitch while both Type II fibers are classed under the term of fast-twitch.
