The Filament Lattice of Striated Muscle
TL;DR: The effects of lattice change on muscle contraction in vertebrate skeletal and cardiac muscle and in invertebrate striated muscle are reviewed and the force developed, the speed of shortening, and stiffness are compared with structural changes occurring within the lattice.

Changes in thick filament structure during compression of the filament lattice in relaxed frog sartorius muscle.
TL;DR: Equatorial X-ray diffraction patterns from relaxed, chemically-skinned frog sartorius muscles under a range of external osmotic pressures from 0 to 290 torr have been analysed and compared to the pattern from the relaxed intact muscle, showing that in relaxed muscle the thick filament projections are concentrated in regions between adjacent thick filaments, as far as possible from the thin filaments.

Orientation of α-helical peptides in a lipid bilayer
TL;DR: In this paper, X-ray reflections from the bilayer and alpha-helices of pure lipid and lipid containing short alpha-helical peptides were examined by diffraction, together with unoriented samples of pure peptide.

Z-line/I-band and A-band lattices of intact frog sartorius muscle at altered interfilament spacing.
TL;DR: Investigation of the variation in spacing of the square lattice of thin filaments within and near the Z-line in intact frog sartorius muscle over a wide range of osmolarities compared with the corresponding changes in the A-band lattice found an equatorial reflection observed in intact muscle.

Z/I and A-band lattice spacings in frog skeletal muscle: effects of contraction and osmolarity.
TL;DR: Lattice areas calculated for the Z/I and A-band lattices indicate a barrel-shaped sarcomere in the resting state, which may provide a partial explanation for how longitudinal forces produced in the A- band can prod uce a radial expansive force in the Z-line during contraction.
