What's the difference between mollusc and odontophore?
Mollusc
Definition:
(n.) Same as Mollusk.
Example Sentences:
(1) The four hosts (Mollusc -- Crustacean -- Odonat -- Amphibian) are obligatory in the life cycle for it is impossible to infect the Insects directly with the cecariae or the frog (tadpoles as well as adults) with the mesocercariae.
(2) A newly developed method of internal dialysis was applied together with the voltage clamp method to the isolated neurons of molluscs Helix pomatia and Limnea stagnalis.
(3) We have demonstrated that M. edulis, a marine bivalve mollusc, reacts to the vertebrate monokines interleukin-1, -6 and TNF.
(4) On the other hand, the major arsenic compound in fish, crustacea and molluscs has been identified as arsenobetaine, which is an arseno-analog of glycinebetaine, a very common osmo-regulator in living organisms.
(5) The microsporidia are a group of unusual, obligately parasitic protists that infect a great variety of other eukaryotes, including vertebrates, arthropods, molluscs, annelids, nematodes, cnidaria and even various ciliates, myxosporidia and gregarines.
(6) Natural crystals of ferritin occurring in the yolk platelets of a mollusc oocyte were studied.
(7) Sensory neurons of the photic pathway in the nudibranch mollusc Hermissenda crassicornis are cholinergic and the synaptic interactions between the photic and vestibular systems have been well characterized electrophysiologically.
(8) Whatever the type of TM-NTM association (lasting association, during prepatent period and production period, association only during the exposure of the molluscs to the miracidia), the presence of NTM involved a significant increase of S. mansoni cercarial production.
(9) It was demonstrated earlier that PAF-positive cells located in the gut epithelium of the same molluscs show immunostaining with mammalian anti-insulin serum which indicates the production of insulin or insulin-like substance.
(10) The fluorescent dye 5(6)-carboxyfluorescein (5-CF) travels quickly up the nerves of the gastropod mollusc, Lymnaea stagnalis into the buccal ganglia and fills the cell bodies in 1-3 h. 5-CF filled neurones can be located in the intact ganglia with low intensity blue light.
(11) Recently, such a developmental strategy has been used to investigate the functional assembly of different forms of non-associative learning (habituation, dishabituation and sensitization) in the marine mollusc Aplysia.
(12) Habituation, one of the simplest behavioral paradigms for studying memory, has recently been examined on the cellular level in the gill-withdrawal reflex in the mollusc Aplysia and in the escape response in cray-fish.
(13) The anti-G beta, gamma antibodies recognized a 35-36-kDa protein in brain of vertebrates such as mammals (rat), avians (pigeon), amphibians (frog), fish (trout), and reptiles (turtle) but not in the invertebrates such as molluscs (snail) and insects (locust).
(14) We have studied the effects of dopamine on the gill withdrawal reflex evoked by tactile siphon stimulation in the margine mollusc Aplysia.
(15) It seems that most mollusc infections occur in February-March and at the end of summer-beginning of autumn periods.
(16) The development of microparticulate food particles for marine suspension-feeders is discussed with respect to the difficulties of nutrient delivery in the aquatic environment and to feeding and digestion in crustacea and bivalve molluscs.
(17) The structure and function of the digestive gland of the gastropod mollusc, Bithynia tentaculata, was investigated using ultrastructural, histochemical, and cytochemical techniques.
(18) The bag cells of the marine mollusc Aplysia are well-characterized neuroendocrine cells that initiate egg laying, but the natural stimulus triggering bag-cell activity has not been determined.
(19) Immunochemically, the major common epitope expressed by the neutral fraction glycolipids of the 3 taeniid species is the same or very similar to the glycosphingolipid, neogalatriaosyl ceramide derived from the marine mollusc Turbo cornutus (Gal(beta 1-6) Gal(beta 1-6) Gal(beta 1-1)Cer).
(20) Pharmacologic activation of endogenous protein kinase C (PKC) together with elevation of the intracellular Ca2+ level was previously shown to cause reduction of two voltage-dependent K+ currents (IA and ICa2+-K+) across the soma membrane of the type B photoreceptor within the eye of the mollusc Hermissenda crassicornis.
Odontophore
Definition:
(n.) A special structure found in the mouth of most mollusks, except bivalves. It consists of several muscles and a cartilage which supports a chitinous radula, or lingual ribbon, armed with teeth. Also applied to the radula alone. See Radula.
Example Sentences:
(1) The odontophoral cells are variable in size; they contain glycogen-filled "cores" as well as bundles of peripherally located filaments resembling myofilaments; and they are innervated like muscle cells.
(2) The odontophore and connective tissue-filled portion of the radular sac (called the "collostyle") of the slug, Limax maximus, were examined by light and electron microscopy.
(3) The parenchyma of the odontophore consists of modified muscle cells which are organized into irregular groups by incomplete trabeculae composed of conventional muscle cells.
(4) The extracellular matrix of the odontophore is very sparse and contains glycogen and fibrillar material but no histochemically demonstrable acidic mucosubstances.
(5) Both the radular sac and odontophore retractor muscles of Buccinum undatum depend upon [Ca]0 to raise the [Ca]i concentration of the contractile system to activation level.
(6) The present study demonstrates that cranial cartilage of Loligo (squid) and odontophore cartilage of Busycon (marine snail) also mineralize in vitro in hydroxyapatite-metastable media, but not in carbonate-metastable media.
(7) Their activities were measured in the gill cartilage of the Atlantic horseshoe crab, Limulus polyphemus, and the odontophore cartilage of the marine whelk, Busycon canaliculatum.
(8) The roughly U-shaped odontophore possesses a thin capsule composed of connective tissue.
(9) Mineralization occurred more rapidly in Eusycon odontophore cartilage which has a significantly higher content of phosphatidyl serine than in Limulus gill or Loligo head cartilages.
