Muscle architecture : ウィキペディア英語版 | Muscle architecture Muscle architecture is the physical arrangement of muscle fibers at the macroscopic level that determines a muscle’s mechanical function. There are several different muscle architecture types including: parallel, pennate and hydrostats. Force production and gearing vary depending on the different geometries of the muscle. Some parameters used in architectural analysis are muscle length (Lm), fiber length (Lf), pennation angle (θ), and physiological cross-sectional area (PCSA). ==Architecture types== Parallel and pennate (also known as pinnate) are two main types of muscle architecture. A third subcategory, muscular hydrostats, can also be considered. Architecture type is determined by the direction in which the muscle fibers are oriented relative to the force-generating axis. The force produced by a given muscle is proportional to the cross-sectional area, or the number of parallel sarcomeres present.
