sarcomere
noun[ C ]
anatomy specializeduk /ˈsɑː.kəʊ.mɪər/ us /ˈsɑːr.koʊ.mɪr/
any of the smaller parts that form a myofibril(= a thread-like structure inside a muscle cell that makes the muscle move):
Each fibre contains several bundles of myofibrils, with filaments arranged longitudinally in repeating units known as sarcomeres.
Sustained sarcomere contraction results in increased metabolism and generates a localized energy crisis.
During contraction, the myosin grabs onto the actin and pulls the filaments past it, shortening the sarcomere.
Hypertrophic cardiomyopathy is a heterogeneous condition affecting the sarcomere.
Muscle tension and median sarcomere length were displayed on screen during the experiments.
