Cephalopod Obliquely striated muscle Operating length range Length–force relationship Transmural gradient of strain Hollow, cylindrical muscular organs and bodies are common in animals, especially soft-bodied invertebrates. Such body plans are effective in providing mechanical support for many...

... obliquely striated muscles. The cells approximate each other closely with minimal intervening intercellular connective tissue. Our physiological experiments, conducted at 17°C, showed that the longitudinal muscle fibers of the funnel retractor were activated rapidly (8 ms latent period following stimulation...

..., the SMR and CMP fibers of both paralarvae and adults exhibited the myofilament arrangements typical of obliquely striated muscle cells but the angle of obliquity of the dense bodies was 22.8±2.4 deg. and 4.6±0.87 deg. for paralarvae and adults, respectively. There were also differences in the distribution...

...Joseph T. Thompson; John A. Szczepanski; Joshua Brody SUMMARY The centrally located, mitochondria-poor (CMP) and superficially located,mitochondria-rich (SMR) circular muscle fibres in the mantles of some squids provide one of the few known examples of specialization in an obliquely striated muscle...

...Brian J. Milligan; N. A. Curtin; Quentin Bone ABSTRACT The mechanical properties of obliquely striated muscle fibres were investigated using thin slices of mantle from squid Alloteuthis subulata and cuttlefish Sepia officinalis . Brief tetani or twitch stimuli were used as this pattern is likely...

..., differing in their ultrastructural and behavioural properties. The transverse muscle of the tentacles consists of specialized muscle fibres that exhibit cross-striation and unusually short sarcomeres and thick filaments. The transverse muscle of the arms consists of obliquely striated muscle fibres...
