.... This prolonged state of contraction is called catch, and the maintenance of catch force is at least 10 times more economical than the contraction that precedes catch. This mechanism has been extensively studied in the anterior byssus retractor muscle (ABRM) of Mytilus edulis ( Rüegg, 1971 , 1986 ). 31 8...

...J. Zange; H. O. Pörtner; A. W. H. Jans; M. K. Grieshaber ABSTRACT The intracellular pH (pHi) of the anterior byssus retractor muscle (ABRM) of Mytilus edulis L. was estimated during rest and during a contraction-catch-relaxation cycle by the distribution of [ 14 C]DMO and by 31 P-NMR spectroscopy...

...Mohammad Diab; WM. F. Gilly ABSTRACT Catch was induced in the spine ligaments of Strongylocentrotus franciscanus (Agassiz) (surrounding muscle and nervous tissue removed) by mechanical agitation. When the catch mechanism is set, the tensile stiffness of urchin ligament can change by nearly an order...
