What's the difference between decapod and hexapod?

Decapod


Definition:

  • (n.) A crustacean with ten feet or legs, as a crab; one of the Decapoda. Also used adjectively.

Example Sentences:

  • (1) Clearance of foreign materials from the hemocoel of decapod crustaceans involves several distinct kinds of cells.
  • (2) Single actin control was found in the fast muscles of decapods, in mysidacea, in a single sipunculid species, and in vertebrate striated muscles.
  • (3) The luciferin of the bioluminescent decapod shrimp, Oplophorus gracilorostris, was purified and studied with respect to u.v.
  • (4) In the walking legs of decapod crustaceans, intersegmental reflex actions originate from various joint proprioceptors.
  • (5) This suggests that the mechanisms of cuticle secretion do not undergo marked changes in activity as they do in decapods; presumably this relative continunity is related to the much shorter molt cycle of cladocerans.
  • (6) Similar inclusions were not found in the leg axons of a variety of other decapod crustaceans.
  • (7) Accordingly, the function of this organ is probably the same in decapods and Armadillidium.
  • (8) Also, in decapod crustaceans a peptidic neurodepressing hormone (NDH) modulates neuroelectrical and behavioural rhythmicity.
  • (9) In Crustaceans, the free amino acid composition of the hemolymph thus appears, both quantitatively and qualitatively, to be a biochemical character of marine Isopods when compared to Oniscoids Isopods and to Decapods.
  • (10) Possible implications of these findings for phylogenetic relations of decapod crustaceans and for the evolution of neural circuits are discussed.
  • (11) The gross anatomy of the hepatopancreas of this species is simpler than that of decapods, but microscopically the cells are similar in both.
  • (12) While much less genically variable than other invertebrates, Homarus is not atypical when compared with eleven decapod species that average 5.8% heterozygosity.
  • (13) Neurotransmitters used by the STG motoneurons of stomatopods are compared to those of decapods.
  • (14) In comparison with the other trypsins from the Crustacean decapods, the shrimp enzymes have four pairs of disulfide bonds, intermediary between the crayfish trypsin (three pairs) and the crab trypsin (five pairs), and are immunochemically different from them.
  • (15) Myosin control is not found in striated vertebrate muscles and in the fast muscles of crustacean decapods, although regulatory light chains are present.
  • (16) An overview of studies on the decapod crustacean cardiac ganglion is given emphasizing contributions to questions of general interest in cellular neurophysiology.
  • (17) Analysis of data obtained from molecular hybridization of 3H-labeled repetitious DNA has been utilized to reconstruct the broad outlines of phylogenetic relationships among decapod Crustacea.
  • (18) In the crab Carcinus maenas, as in other decapod crustaceans, the extracellular pH varies with temperature so that the relative alkalinity remains approximately constant.
  • (19) These results confirmed earlier reports by Yonge (1924) and van Weel (1955) on the decapods, Nephrops norvegicus and Atya spinides, respectively.
  • (20) In particular, the inhibitory axons of the reptantian decapod leg have been reported, in various studies within four different infraorders, to innervate anywhere from one to all seven of the leg's distal muscles and to vary in number from two to four.

Hexapod


Definition:

  • (a.) Having six feet.
  • (n.) An animal having six feet; one of the Hexapoda.

Example Sentences:

  • (1) The cercal system, which may have evolved with the first terrestrial hexapods, reaches its zenith in the orthopteroid insects, but was replaced in holometabolan insects by visual startle mechanisms with descending giant interneurons.
  • (2) Maximum parsimony analyses and monophyly testing within arthropods indicate that myriapods (millipedes and centipedes) form a sister group to all other assemblages, whereas crustaceans (shrimps and lobsters) plus hexapods (insects and allied groups) form a well-supported monophyletic group.
  • (3) Recaptured migrants with infected ticks indicate that they transmit B. burgdorferi to hexapod larvae.
  • (4) Parsimony analysis further suggests that onychophorans form a sister group to chelicerates (spiders and scorpions) and crustaceans plus hexapods, but this relationship is not well supported by monophyly testing.
  • (5) The vectors are the hexapod larvae of Rhipicephalus sanguineus, R. turanicus and H. truncatum; the filarial infective stages appear during the larval-nymph moult of the vector (11 days at 26 degrees C).
  • (6) Histological and ultrastructural analysis of the development of C. roussilhoni--a filarial parasite of A. africanus with skin-dwelling microfilariae--in the hexapod, larva of R. sanguineus.
