What's the difference between leaflet and pinnate?

Leaflet


Definition:

  • (n.) A little leaf; also, a little printed leaf or a tract.
  • (n.) One of the divisions of a compound leaf; a foliole.
  • (n.) A leaflike organ or part; as, a leaflet of the gills of fishes.

  • (17) Angiographic features felt to indicate valve tearing were present following 17 of 25 procedures and included increased excursion or straightening of leaflets, localized change in leaflet motion (flail leaflet), and the presence of an additional contrast jet through the valve.
  • (18) Furthermore, the long axis of the right and left atria was measured from the center of the apposed atrioventricular valve leaflets to the posterior atrial wall, and the sizes of the atrial chambers were defined using their widths at the prospective broadest points through the area of foramen ovale.
  • (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.
  • (14) The medial head contains fewer type I fibers and is composed of relatively longer myofibers (15-20 mm long), also arranged in a pinnate fashion but less heavily invested with connective tissue.
  • (15) Therefore, if twisting has been minimized in New World monkeys as suggested by their thin corpora, other changes in the craniofacial musculoskeletal complex, such as different muscle recruitment or pinnation patterns, may be responsible.
  • (16) This region is largely composed of short fibers (5-7 mm long) arranged in a pinnate fashion and heavily invested with connective tissue.
  • (17) Three architectural patterns that deserve discussion are the classical arrangement of fibers in pinnate patterns, the more recent assumption of sarcomere equivalence, and the issue of compartmentation.

  • (19) Postnatal development of the masticatory musculature takes place on the basis of the pinnation existing prior to birth and consists in secondary pinnation.
  • (20) The PCSA of each muscle was calculated as muscle volume times the cosine of the angle of fiber pinnation divided by fiber length, where published fiber length:muscle length ratios were used to estimate fiber lengths.
