What's the difference between cirri and cirrous?

Cirri


Definition:

  • (n. pl.) See Cirrus.
  • (pl. ) of Cirrus

Example Sentences:

  • (1) Tyr-tubulin is principally at the bases of cirri and membranelles.
  • (2) These sets, however, are incomplete, with certain structures, most notably cirri of the right marginal type, missing near the line of symmetry.
  • (3) The laterofrontal (LF) cirri on isolated gill filaments of Mytilus edulis, prepared in natural seawater, are active and initially beat with an average frequency of about 8 Hz (with a range of 6-14 Hz).
  • (4) The cirri of the ciliate Euplotes all asslumne the "reversed" orientation whenever the cell is depolarized and the "forward" orientation whenever the cell is hyperpolarized.
  • (5) This results in the differentiation of maxillary structures like cirri and mouth hooks in places where they normally do not appear, and represents a phenomenon of autocatalysis of homeotic gene function that differs from the normal activation process.
  • (6) The member on the pair's left resorbs the collar membranelles and the frontal and right marginal cirri; the member on the pair's right resorbs the central and posterior membranelles (lapel) of the adoral zone of membranelles.
  • (7) Under these conditions, the threshold of the LF cirri arrest response is again found to occur as the L cilia attain a beat frequency of 12-14 Hz.
  • (8) When a mirror-image doublet is bisected longitudinally to separate the RH and LH components physically, each fragment undergoes a regeneration process that restores a complete set of cortical structures, including the previously missing cirri of the right marginal type.
  • (9) The orientation responses of thte cirri are appatently independent of intracellular "neuromotor" fibrils previously assigned a coordinating function, as they persist after the fibrils are transected.
  • (10) Consequently, a 4-5-hour-old pair contains slightly more than one complete set of anterior ventral organelles (viz., one extra set of undulating membranes) and two complete sets of ventral and anal cirri.
  • (11) A combination of 10(-7) M 5HT and 0.5 mM IBMX in ASW mimics high (greater than 10(-6) M) 5HT concentrations by arresting the LF cirri and increasing the beat frequency of the L cilia.
  • (12) Exposure to higher concentrations of 5HT (greater than 10(-7) M) elevates the beat frequency of the L cilia and simultaneously inhibits the activity of the LF cirri, leading to their arrest in a position at the end of the effective stroke.
  • (13) A concentration of 0.5 mM IBMX mimics low 5HT concentrations (about 10(-7) M) by stimulating the L cilia to beat without affecting the beat frequency of the LF cirri.
  • (14) We document a novel approach for quantitative assessment of ciliary activity, exemplified in rapid three-dimensional cyclic motion of the frontal cirri of Stylonychia.
  • (15) These results suggest that the mechanisms of LF cirri arrest and L cilia activation are mediated by 5HT-induced changes in intracellular cyclic AMP levels.
  • (16) The influence of 5HT on the L cilia and the LF cirri can be reversibly mimicked or enhanced by the phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (IBMX).
  • (17) The exposure of the gill to low levels of 5-hydroxytryptamine (5HT) (10(-8) less than 5HT less than 10(-7) M) has no effect on the activity of the LF cirri but stimulates the L cilia to beat.
  • (18) In the resulting LH cell, all ciliary structures are present in an arrangement that is globally reversed in relation to that found in RH cells; in particular, marginal cirri of the left-marginal type are formed at the cell's right margin, and marginal cirri of the right-marginal type are produced at the cell's left margin.
  • (19) Motor responses of the frontal cirri of the ciliate Stylonychia were recorded at the axial view of the ciliary base with high-speed cinematography.
  • (20) Perfusion of the filament with artificial seawater (ASW), with or without 1% ethanol, has little or no biological effect on the activity of the LF cirri, although a transitory decrease in frequency often accompanies the perfusion process.

Cirrous


Definition:

  • (a.) Cirrose.
