Definition that contains muscle fiber
- fiber any of several elongated, threadlike cells (especially a muscle fiber or a nerve fiber)
- relaxation (physiology) the gradual lengthening of inactive muscle or muscle fibers
- relaxation (physiology) the gradual lengthening of inactive muscle or muscle fibers
- contraction (physiology) a shortening or tensing of a part or organ (especially of a muscle or muscle fiber)
- fibre any of several elongated, threadlike cells (especially a muscle fiber or a nerve fiber)
- fibrillation muscular twitching involving individual muscle fibers acting without coordination
- actomyosin a protein complex in muscle fibers; composed of myosin and actin; shortens when stimulated and causes muscle contractions
- contractility the capability or quality of shrinking or contracting, especially by muscle fibers and even some other forms of living matter
- fasciculation muscular twitching of contiguous groups of muscle fibers
- myofibril one of many contractile filaments that make up a striated muscle fiber
