Role of Ca(2+) in excitation-contraction coupling in echinoderm muscle: comparison with role in other tissues.
The longitudinal muscle of the body wall of Isostichopus badionotus may be considered a model for excitation-contraction coupling in echinoderm muscle. Other echinoderm muscles are reviewed by comparison with the model. Echinoderm muscle is also of interest as a model for 'mutable collagenous tissue'; however, in that tissue, Ca(2+) has been proposed to function both in living control systems and in regulation of non-living interstitial substance.
