Stereo view of 3D structure in fish M-band (Luther & Crowther, 1984). Bony fish are unique amongst vertebrate in that their myosin filaments (labelled M above) have the same orientation within each sarcomere. This enhanced order makes fish muscle ideal for structural analysis. Here the M-bridges (B) crosslink the myosin filaments in the lower half of the stereo depth, while the upper half shows myosin filaments with triangular shafts in the bare region.
