Definition of sarcolemma in English: sarcolemmanoun ˈsɑːkəʊˌlɛməˌsɑrkəˈlɛmə Physiology The fine transparent tubular sheath which envelops the fibres of skeletal muscles. Example sentencesExamples - The newborn larvae migrate from the host's blood vessels through the sarcolemma of striated muscle tissue, where they penetrate and encyst inside an individual muscle cell.
- The usual position of skeletal muscle nuclei and the discovery of the sarcolemma is credited to Bowman.
- EC coupling occurs at specialized regions where the intracellular sarcoplasmic reticulum forms junctions with the sarcolemma or, more frequently, with tubular invaginations of the sarcolemma known as transverse tubules.
- Structural abnormalities included loss of lateral alignment of myofibrils, perturbation of myofibril anchorage to the sarcolemma, abnormal mitochondrial number and organization, and loss of nuclear shape and positioning.
- Desmin and vinculin are functionally related proteins that are present in the membrane-associated dense bodies in the sarcolemma of the smooth muscle cells.
Synonyms covering, cover, case, casing, envelope, sleeve, wrapper
Derivatives adjective Physiology Diffuse fluorescent uptake of procion orange in the cytoplasm of diaphragm muscle fibers identifies sarcolemmal rupture of those individual fibers. Example sentencesExamples - Early mechanical ventilation decreases the sarcolemmal injury and associated diaphragmatic dysfunction.
- Endotoxemia and sepsis also induce mitochondrial dysfunction, sarcolemmal injury, and weakness and fatigability of the diaphragm.
- In the present study, no significant sarcolemmal rupture was noted in EMP-sham animals.
- Additional evidence for ongoing denervation of UA muscle in OSA is provided by the significant increase in sarcolemmal N-CAM staining.
Origin Mid 19th century: from Greek sarx, sark- 'flesh' + lemma 'husk'.
