(19) One valve displayed a fixed outward eversion of the free margin of two leaflets.
(20) To date, 3-dimensional studies have demonstrated that the mitral valve is saddle-shaped in systole, so that apparent superior leaflet displacement in the mediolateral 4-chamber view, often seen in otherwise normal individuals, lies entirely within the bounds defined by the mitral annulus and occurs without leaflet distortion or actual displacement above the entire mitral valve.
Pinnate
Definition:
(a.) Alt. of Pinnated
Example Sentences:
(1) The pinnate structure of the temporal muscle results from the internal tendons, which attach to the coronoid process.
(2) The lengths and pinnation angles of muscle fibers in the medial gastrocnemius (MG) muscle have recently been measured in freely moving cats [Hoffer et al., Progr.
(3) This region appeared to be composed of extrafusal fibers that were shorter and of more oblique pinnation than those in other regions.
(4) The loss of fiber force due to (pinnate, not equivalent) angulation is compensated for by the reduced shortening of fibers in multipinnate arrays.
(5) They are important in those groups of muscles which pass over major joints with changed courses or manifest pronounced pinnation with different courses of their septa.
(6) Conversely, the hamstrings, with small pinnation angles, appeared to be designed to permit large excursions.
(7) The suggestion may also apply to the development of the pinnate structure of muscles of higher vertebrates.
(8) Fiber length and angulation in the complex M. adductor mandibulae externus 2 of a lizard were measured stereotactically; these values correlate well with the hypothesis that the muscle shows equivalence and demonstrate that angulation for pinnation is less constant.
(9) Classical pinnate muscles contain many relatively short fibers positioned in parallel but at an angle to the whole muscle, reducing the per fiber force contribution.
(10) The medial pterygoid muscle with its 7 Sehnenspiegel has the most complex pinnate structure.
(11) The differences in angulation and length observed for the fibers of anatomical muscles may reflect two distinct mechanical requirements: arrangement for pinnation, reflecting an increase in physiological cross-section and arrangement for equivalent placement of sarcomeres, possibly associated with coordination.
(12) The understanding of intermediate architecture, including issues of compartmentation, pinnation, and concatenation, remains more elusive, as some morphologically distinct muscles may be functionally equivalent.
(13) The basic pinnate structures caused by Sehnenspiegel in the jaw muscles are already present in newborn animals.
