What's the difference between pinnule and pinule?

Pinnule


Definition:

  • (n.) One of the small divisions of a decompound frond or leaf. See Illust. of Bipinnate leaf, under Bipinnate.
  • (n.) Any one of a series of small, slender organs, or parts, when arranged in rows so as to have a plumelike appearance; as, a pinnule of a gorgonia; the pinnules of a crinoid.

Example Sentences:

  • (1) Aminergic elements were revealed by glyoxylic acid-induced fluorescence in the branchial nerve, branchial ganglion, branchial vessels, and pinnules in both species.
  • (2) It was noted in the pinnules that there was a much higher concentration of dopamine than serotonin.
  • (3) The younger pinnules or tips of A. fiordensis are less than 3% diphenol by weight.
  • (4) Tactile stimulation of the pinnule evoked a two-component contractile reflex contraction due to activation of the peripheral nerve plexus.
  • (5) In semi-intact preparations, pinnule contractions and junctional transmissions were then measured during 3-s depolarized pulses to L7 (frequency range = 1-44 per 3-s interval).
  • (6) Isolated pinnules of the gill of Aplysia contract when dopamine (DA) is perfused through the bath.
  • (7) As Aplysia age, motor neuronal (L7) elicited gill-pinnule contractions are significantly decreased, as is transmission at pinnule junctions.
  • (8) A weak or moderate tactile stimulus to the mantle elicits gill contraction (gill-withdrawal reflex) as a component of a more extensive withdrawal response; a stimulus applied directly to the gill elicits a localized response of the gill pinnule (pinnule response).
  • (9) Peripheral pathways are necessary and sufficient for the pinnule response.
  • (10) The pinnule often shows irregular, spontaneous contractions which are blocked by high-Mg2+ seawater and 30 mM CoCl2.
  • (11) The trained animals had (a) significantly higher pinnule contractions, (b) a significantly greater increase in pinnule contractions elicited by increasing L7 spike rates, (c) significantly higher double-spike facilitation, and (d) significantly higher facilitation per spike across the four spike trains below or at pinnule contraction threshold.

Pinule


Definition:

  • (n.) One of the sights of an astrolabe.

Example Sentences:

  • (1) Thus, the genetic defect in Pinull is not a complete or partial deletion of the structural gene.
  • (2) Heterozygotes for Pinull and the common normal allele PiM1 have half-normal serum concentrations of A-1-AT.
  • (3) A family in which a Pinull allele for alpha-1-antitrypsin (A-1-AT) segregates has been studied in detail.
  • (4) There are two common deficiency alleles in the European population, proteinase inhibitor (Pi) Z and S. In addition, there are rare Pinull or QO variants which can be difficult to diagnose.
